Mind the gap: Gender disparities in authorship in the Journal of Medical Imaging and Radiation Sciences.

INTRODUCTION: Research studies tracking gender and academic publication productivity in healthcare find gender disparities in research activity, publication, and authorship. Article authorship is one of the important metrics to track when seeking to understand gender inequality in academic career advancement. Research on gender disparities in publication productivity in the field of Medical Radiation Science (MRS) is very limited thus this study analyses and explains potential gender differences in article authorship and acceptance for publication in the Journal of Medical Imaging and Radiation Sciences (JMIRS) for a 5-year period (2017-2021). METHODS: Gender was inferred based on the author's first name or title (e.g., Mr, Mrs or Ms). For those who left the title blank or reported as 'Dr' or 'Prof,' a series of steps were taken to identify their gender. Where gender was impossible to ascribe, these authors were excluded. Descriptive and inferential statistics are reported for the study population. Descriptive and inferential statistics are used. Percentages of females are reported, and males constitute the other portion. Chi-square, slope analysis and z-tests were used to test hypotheses. RESULTS: Results show that female authorship overall and in all categories of authorship placement (i.e., first, last and corresponding) increased over the timeframe reviewed. The percentage gain in the increase was higher than that for male authorship. However, male authorship started from a higher baseline in 2017 and has also increased year on year and overall, as well as in each placement category examined. More female authors were in the MRS sub-specialism Radiation Therapy (RT) than in the other MRS sub-specialisms. Analysis of the acceptance rate of articles with female authors shows a weak downward trend, and this may be related to higher submission and acceptance rates of articles by male authors during the same period. CONCLUSION: Male authors are overrepresented in all categories, which raises questions about the persistence of gender disparities in JMIRS authorship and article acceptance. Positive trends in female authorship indicate progress, yet there is the persistence of the significant under-representation of women in the Medical Radiation Sciences workforce in academic publishing. Recruiting more males to address the gender imbalance in the profession should not be at the expense of females' career progression.

An investigation into the knowledge, attitudes, and practice of radiation protection in interventional radiology and cardiac catheter-laboratories.

BACKGROUND: According to current literature, there is a lack of information regarding the radiation protection (RP) practices of interventional radiology (IR) and cardiology catheter laboratory (CCL) staff. This study aims to determine the RP practices of staff within IR and CCLs internationally and to suggest areas for improvement. METHODS: A cross-sectional study in the form of an online questionnaire was developed. Participation was advertised via online platforms and through email. Participants were included if they were healthcare professionals currently working in IR and CCLs internationally. Questionnaire design included Section 1 demographic data, Section 2 assessed RP training and protocols, Section 3 surveyed the use of different types of RP lead shields, both personal and co-worker use and Section 4 assessed other methods of minimising radiation dose within practice. Questions were a mix of open and closed ended, descriptive statistics were used for closed questions and thematic analysis was employed for open ended responses. RESULTS: A total of 178 responses to the questionnaire were recorded with 130 (73 %) suitable for analysis. Most respondents were female (n = 94, 72 %) and were radiographers (n = 97, 75 %). Only 68 (53 %) had received training, the majority receiving this in-house (n = 54, 79 %). 118 (98 %) of respondents had departmental protocols in place for RP. Radiology managers (n = 106, 82 %) were most likely to contribute to such protocols. Multiple methods of dose minimisation exist, these include low-dose fluoroscopy, staff rotation, radiation dose audits and minimal time in the controlled areas. Respondents reported that lead apron shields were wore personally by 99 % of respondents and by co-workers in 95 % of cases. CONCLUSION: The practices of RP by IR and CCL staff in this survey was variable and can be improved. The unavailability of basic radiation protection tools and RP specific training courses/modules were some of the reasons for sub-optimal self-protection against ionising radiation reported by respondents.

An investigation into the current perceptions of Irish Radiographers regarding patient-practitioner communication.

INTRODUCTION: Many of the tasks performed by radiographers rely on effective communication with patients. This study aims to evaluate radiographers' experiences communicating with patients to determine what communication skills they believe they have, challenges they encounter and any familiarity with communication tools. It also assesses their willingness to accept further training and utilise recognised scripted communication tools, such as AIDET (Acknowledge, Introduce, Duration, Explanation and Thank you). METHODS: Data were collected using an online survey deployed using the MS Forms platform. The survey consisted of 42 questions: 12 qualitative 'open-ended' questions and 30 'close-ended' quantitative questions. The survey remained open between March and May 2022. Quantitative data were analysed using descriptive statistics and qualitative responses using thematic content analysis. Cross distribution analysis, basic percentages, and graphic bar charts were used for quantitative data analysis. RESULTS: One hundred and nine radiographers completed the questionnaire. Quantitative analysis found that 84 % (n = 87) of radiographers had not received additional post-qualification training in patient communication. Five communication themes emerged from the thematic analysis; (1) Expectations, (2) Education, (3) Improvements, (4) Errors, and (5) Communication Tools. The scripted communication tool AIDET, according to 86 % (n = 89) of respondents, was perceived to be potential helpful in improving radiographer-patient interactions. CONCLUSION: Radiographers do not believe they have received adequate training for communicating with patients and would like to receive additional training and education. AIDET could be a useful communication tool as a starting guide for less experienced radiographers. There is a need for further studies that explore the use and effectiveness of scripted communication tools in radiographers' communications skills. In addition, additional post-registration training opportunities need to be available for radiographers in patient communication.

Evolving radiographic practice: Identifying possible skill requirements for future radiographers practicing in the United Arab Emirates (UAE).

AIM: This study aims to identify the prospective skill requirements for future radiographers practising in the United Arab Emirates (UAE). Such information will inform educational institutions, healthcare organisations, and policymakers in developing effective strategies. METHODS: A cross-sectional study was conducted involving currently practising radiographers, nuclear medicine technologists, sonographers, and radiation therapists in the UAE (n =74). A comprehensive survey questionnaire was developed and validated through piloting and expert consultations. Ethical approval was obtained, and data were collected through purposive sampling. Descriptive statistics, reliability analysis, Chi-square tests, and factor analysis were employed in the data analysis. RESULTS: The results showed that 73%, 47.3%, 43.2%, 40.5%, 39.2%, 33.8% interested in radiology safety, image interpretation, interprofessional and interpersonal skills, research and managerial skills, Picture Archiving and Communication System (PACS) administration and AI (Artificial Intelligence) and, clinical supervision and assessment, respectively. The factor analysis showed four factors factor considered for CPD training are training settings (15.12), training topics (1.88), CPD credits (1.72) and, presenter and expenses (1.49). CONCLUSION: This study sheds light on the CPD requirements and aspirations of radiographers in the UAE, offering insights into their preferences and challenges. These findings can inform strategies for improving CPD opportunities and ensuring that radiographers are equipped to meet the evolving healthcare demands in the UAE, including performing enhanced practice. IMPLICATIONS FOR PRACTICE: Development of flexible and comprehensive CPD programmes tailored to radiographers' career interests is required. Employers should provide financial support and flexibility in training options. Regulatory bodies should continue to mandate CPD, fostering a culture of lifelong learning. Supportive work environments, interdisciplinary collaboration, and technological fluency are crucial. Emphasising patient-centred care, research opportunities, and continuous assessment further enhances radiography practice.

Expansion of Typical Values for Paediatric Patients in Ireland and Comparison with Published DRLs - Experiences of a Single Institution.

INTRODUCTION: To reduce the risks involved with ionising radiation exposure, typical values (TVs) and diagnostic reference levels (DRLs) have been established to help keep radiation doses 'as low as reasonably practicable. TVs/DRLs provide standardised radiation dose metrics that can be used for comparative purposes. However, for paediatrics, such values should consider the size of the child instead of their age. This study aimed to establish and compare paediatric TVs for chest, abdomen and pelvis radiography. METHODS: Study methods followed processes for establishing paediatric DRLs as outlined by the Health Information and Quality Authority (HIQA). Kerma-area product (KAP) values, excluding rejected images, were retrospectively acquired from the study institution's Picture Archiving and Communications System (PACS). Paediatric patients were categorised into the following weight-based groupings (5 to <15 kg, 15 to <30 kg, 30 to <50 kg, 50 to 80 kg) and stratified based on the examination that was performed (chest, abdomen, and pelvis), and where it was performed (the different X-ray rooms). Anonymised data were inputted into Microsoft Excel for analysis. Median and 3rd quartile KAP values were reported together with graphical illustrations. RESULTS: Data from 407 X-ray examinations were analysed. For the previously identified weight categories (5 to <15 kg, 15 to <30 kg, 30 to <50 kg, 50 to 80 kg), TVs for the chest were 0.10, 0.19, 0.37 and 0.53 dGy.cm2, respectively. For the abdomen 0.39, 1.04, 3.51 and 4.05 dGy.cm2 and for the pelvis 0.43, 0.87, 3.50 and 7.58 dGy.cm2. Between X-ray rooms TVs varied against the institutional TVs by -60 to 119 % (chest), -50 to 103 % (abdomen) and -14 and 24 %% (pelvis). CONCLUSION: TVs in this study follow established trends with patient weight and examination type and are comparable with published literature. Variations do exist between individual examination rooms and reasons are multifactorial. Given that age and size do not perfectly correlate further work should be undertaken around weight-based TVs/DRLs in the paediatric setting.

Risk factors associated with the development of osteoradionecrosis (ORN) in Head and Neck cancer patients in Ireland: A 10-year retrospective review.

BACKGROUND AND PURPOSES: To assess osteoradionecrosis (ORN) incidence in a population of Irish Head and Neck cancer (HNC) patients, and assess precipitating factors that may contribute to ORN development to aid prevention. MATERIALS AND METHODS: Review of 1050 HNC patients attending the Dental Oncology Clinic, CUDSH between 2010 and 2021 identified 47 cases of ORN. Medical, dental and radiotherapy records of these forty-seven patients were retrospectively reviewed. Patient-, tumour-, and treatment-related variables were investigated in association with osteoradionecrosis development. Analysis conducted using SPSS, Pearson's Chi-square test (p < 0.05), and ordinal regression model. RESULTS: ORN incidence was 4.4 %. Median time from radiotherapy (RT) to ORN development was 9.5 months (range 1-98.5 months). ORN development within the mandibular surgical site was significant (p <.001), presenting at a higher Notani grade (p =.002), in mid-mandibular body region (p =.028), at radiation doses ≥ 60 Gy (p =.035), due to induced causes (p =.029), and without resolution (p =.019). CONCLUSION: This is the first retrospective study of ORN in HNC patients in Ireland over 10-year period. ORN incidence was extremely low (4.4%). As patients reported high smoking/alcohol use and poor dental attendance pre-diagnosis, this suggests intensive dental intervention pre/post-diagnosis contributed to low ORN rates. Mandibular surgery pre-RT increased risk of developing ORN at the surgical site. Therefore, we recommend future treatment planning should contour the surgical site, designating it an organ at risk (OAR), assigning a dose constraint, where oncologically possible, with emphasis on reducing the hot-spot to this region; findings reinforce importance of life-long expert dental care to reduce ORN incidence.

Black box no more: A cross-sectional multi-disciplinary survey for exploring governance and guiding adoption of AI in medical imaging and radiotherapy in the UK.

BACKGROUND: Medical Imaging and radiotherapy (MIRT) are at the forefront of artificial intelligence applications. The exponential increase of these applications has made governance frameworks necessary to uphold safe and effective clinical adoption. There is little information about how healthcare practitioners in MIRT in the UK use AI tools, their governance and associated challenges, opportunities and priorities for the future. METHODS: This cross-sectional survey was open from November to December 2022 to MIRT professionals who had knowledge or made use of AI tools, as an attempt to map out current policy and practice and to identify future needs. The survey was electronically distributed to the participants. Statistical analysis included descriptive statistics and inferential statistics on the SPSS statistical software. Content analysis was employed for the open-ended questions. RESULTS: Among the 245 responses, the following were emphasised as central to AI adoption: governance frameworks, practitioner training, leadership, and teamwork within the AI ecosystem. Prior training was strongly correlated with increased knowledge about AI tools and frameworks. However, knowledge of related frameworks remained low, with different professionals showing different affinity to certain frameworks related to their respective roles. Common challenges and opportunities of AI adoption were also highlighted, with recommendations for future practice.

Radiographers' perceptions of the experiences of patients with dementia attending the radiology department.

BACKGROUND: Patients with dementia frequently present to the Radiology Department. However, stigmas have been recorded amongst radiographers surrounding imaging persons with dementia (PwD). This study aimed to investigate the impact of PwD attending the Radiology Department for imaging and the resultant effects to all patients, radiographers, and the Department from the perspectives of the examining radiographer. METHODS: A paper-based questionnaire of radiographers' perceptions and experiences of individual examinations 'termed an interaction form' was created and made available in a public hospital in Ireland for a period of eight weeks. Radiographers completed the interaction form collecting data regarding individual imaging examinations of PwD. The form comprised sixteen closed and one open-ended question on the radiographers' individual perspectives of PwDs' abilities and distress levels, carers and comforters and their role in the examination, what the radiographer found helpful in the interaction, and any adverse events. Data were analysed using a combination of descriptive analysis and thematic content analysis. RESULTS: Thirty-three interaction forms were completed by the participating radiographers. The modality most commonly represented in the survey was general X-ray (58%). Radiographers reported 84% of examinations for PwD required extra time, with 27% of examinations required repeat imaging and 69% of patients appeared distressed. A carer helped facilitate the completion of 77% of examinations. Qualitative data indicated that distractive and communicative techniques were used by radiographers to make the patient feel more comfortable and help with examination success. CONCLUSION: PwD often require more time for radiological examinations, they often need repeat imaging and re-scheduling of an examination at a more appropriate time. These factors need to be considered when scheduling and performing radiological examinations. Patient distress was frequently encountered, this area may benefit from further research and dedicated practitioner training which could help drive improvements in patient experience.

Diagnostic reference levels in spinal CT: Jordanian assessments and global benchmarks.

BACKGROUND: To reduce radiation dose and subsequent risks, several legislative documents in different countries describe the need for Diagnostic Reference Levels (DRLs). Spinal radiography is a common and high-dose examination. Therefore, the aim of this work was to establish the DRL for Computed Tomography (CT) examinations of the spine in healthcare institutions across Jordan. METHODS: Data was retrieved from the picture archiving and communications system (PACS), which included the CT Dose Index (CTDI (vol) ) and Dose Length Product (DLP). The median radiation dose values of the dosimetric indices were calculated for each site. DRL values were defined as the 75th percentile distribution of the median CTDI (vol)  and DLP values. RESULTS: Data was collected from 659 CT examinations (316 cervical spine and 343 lumbar-sacral spine). Of the participants, 68% were males, and the patients' mean weight was 69.7 kg (minimum = 60; maximum = 80, SD = 8.9). The 75th percentile for the DLP of cervical and LS-spine CT scans in Jordan were 565.2 and 967.7 mGy.cm, respectively. CONCLUSIONS: This research demonstrates a wide range of variability in CTDI (vol)  and DLP values for spinal CT examinations; these variations were associated with the acquisition protocol and highlight the need to optimize radiation dose in spinal CT examinations.

The prevalence of harassment of diagnostic radiography and radiation therapy students whilst on clinical placement in the Republic of Ireland.

Objective: To determine if student radiographers and radiation therapists experience harassment (verbal, physical or sexual) while on clinical placement and their awareness of policies in place to report such incidents.Methods: An online questionnaire developed from the World Health Organisation's questionnaire on workplace violence in healthcare and the higher education authority (HEA) national survey of student experiences of sexual violence and harassment in Irish HEIs was used. Undergraduate and postgraduate diagnostic radiography and radiation therapy students in the Republic of Ireland to be included and have completed a minimum of four weeks of clinical placement. Our of 256 students, 98 filled out the survey.Results: Forty-one per cent (n = 40) of students reported experiencing at least one incident of harassment. Thirteen per cent reported experiencing two forms of harassment, and 2 students reported experiencing verbal, physical and sexual harassment. Verbal harassment (n = 33) and sexual (n = 16) were the most common form of harassment while physical harassment was experienced 7 participants. Ninety-one per cent (n = 88) of participants reported they don't believe they have received sufficient training in dealing with incidents of physical, verbal or sexual harassment.Conclusion: Harassment of student radiographers and radiation therapists is occurring while on placement. Male patients are the modal perpetrator, and most incidents go unreported. Students are not empowered to report an incident of harassment and are sometimes unaware of how to report harassment.

Ultrasound assessment of testicular volume - An interobserver variability study.

BACKGROUND: Ultrasonography measurement of the testicles and subsequent calculation of the testicular volume is recommended as a part of a standard scrotal ultrasound examination. The interobserver variability of testicular volume measurement has implications for surgical recommendations. Therefore, this study aimed to investigate the interobserver variability in the measurement of testicular volume. METHODS: Interobserver variability was established by comparing testicular measurements performed by two observers on the same patient during the same clinical appointment. The observers were blinded to each other's measurements. Testicular volume was calculated using the Lambert formula: length x width x height x 0.71. A total of three observers, A, B and C, participated in the study. The observers had between 4 to 20 years' experience with scrotal ultrasound examinations. RESULTS: In total, 24 patients' were included (48 testicles). The patient´s mean age was 43 years (range 19-75 years). The overall mean right testicular volume was 19.8 ml (range 7.3-31.6 ml), and the left was 20.1 ml (range 7.1-36.1 ml). The interclass correlation coefficient (ICC) between observer A and B was excellent (ICC= 0.98, CI:0.92-0.99), between observer A and C, was excellent (ICC=0.91, CI: 0.77-0.97) and between B and C good (ICC=0.82, CI:0.51-0.93). CONCLUSION: Variability in estimating testicular volume is low, with interobserver agreement ranging from good to excellent. Ultrasound provides a highly reproducible tool to determine testicular volume.

Black box no more: a scoping review of AI governance frameworks to guide procurement and adoption of AI in medical imaging and radiotherapy in the UK.

Technological advancements in computer science have started to bring artificial intelligence (AI) from the bench closer to the bedside. While there is still lots to do and improve, AI models in medical imaging and radiotherapy are rapidly being developed and increasingly deployed in clinical practice. At the same time, AI governance frameworks are still under development. Clinical practitioners involved with procuring, deploying, and adopting AI tools in the UK should be well-informed about these AI governance frameworks. This scoping review aimed to map out available literature on AI governance in the UK, focusing on medical imaging and radiotherapy. Searches were performed on Google Scholar, Pubmed, and the Cochrane Library, between June and July 2022. Of 4225 initially identified sources, 35 were finally included in this review. A comprehensive conceptual AI governance framework was proposed, guided by the need for rigorous AI validation and evaluation procedures, the accreditation rules and standards, and the fundamental ethical principles of AI. Fairness, transparency, trustworthiness, and explainability should be drivers of all AI models deployed in clinical practice. Appropriate staff education is also mandatory to ensure AI's safe and responsible use. Multidisciplinary teams under robust leadership will facilitate AI adoption, and it is crucial to involve patients, the public, and practitioners in decision-making. Collaborative research should be encouraged to enhance and promote innovation, while caution should be paid to the ongoing auditing of AI tools to ensure safety and clinical effectiveness.

The effect of contact radiation shielding on breast dose during CT abdomen-pelvis: a phantom study.

This study aims to investigate if contact shielding reduces breast radiation dose during computed tomography (CT) abdomen-pelvis examinations using automatic tube current modulation to protect one of the four most radiosensitive organs during CT examinations. Dose measurements were taken with and without contact shielding across the anterior and lateral aspects of the breasts and with and without organ dose modulation (ODM) to quantify achievable dose reductions. Although there are no statistically significant findings, when comparing with and without shielding, the mean breast surface dose was reduced by 0.01 µSv without ODM (1.92-1.91 µSv, p = 0.49) and increased by 0.03 µSv with ODM (1.53-1.56 µSv, p = 0.44). Comparing with and without ODM, the mean breast surface dose was reduced by 0.35 µSv with shielding (1.91-1.56 µSv, p = 0.24) and by 0.39 µSv without shielding (1.92-1.53 µSv, p = 0.17). The addition of contact shielding does not provide significant breast surface radiation dose reduction during CT abdomen-pelvis.

Exploring radiographers' perceptions and knowledge about patient lead shielding: a cross-sectional study in Greece and Cyprus.

The present study aimed to explore radiographers' knowledge, clinical practice and perceptions regarding the use of patient lead shielding in Greece and Cyprus. Qualitative data were analyzed using conceptual content analysis and through the classification of findings into themes and categories. A total of 216 valid responses were received. Most respondents reported not being aware of the patient shielding recommendations issued by the American Association of Physicists in Medicine (67%) or the guidance issued by the British Institute of Radiology (69%). Shielding-related training was generally not provided by radiography departments (74%). Most of them (85%) reported that they need specific guidance on lead shielding practices. Also, 82% of the respondents said that lead shielding should continue to be used outside the pelvic area when imaging pregnant patients. Pediatric patients are the most common patient category to which lead shielding was applied. Significant gaps in relevant training have been identified among radiographers in Greece and Cyprus, highlighting the need for new protocols and provision of adequate training on lead shielding practices. Radiography departments should invest in appropriate shielding equipment and adequately train their staff.

Radiographers' attitudes toward the use of lead contact shielding.

INTRODUCTION: Lead contact shielding has been a crucial component of patient radiation protection since it was first introduced in the early 1900s. Concerns surrounding the hereditary effects of ionising radiation were a driver for using lead shielding. Recently the American Association of Physics in Medicine (AAPM) and the British Institute of Radiology (BIR) have published position papers that suggest that lead contact shielding is no longer needed due to reduced radiation doses for x-ray examinations. This work examines radiographers' opinions on these position papers. METHODS: An online survey with quantitative and qualitative elements was designed to explore knowledge and attitudes toward the BIR and AAPM position papers. The population for this survey was all qualified radiographers. RESULTS: The majority (59%) of participants are aware of the AAPM guidance, and 76% are aware of the BIR guidance. Given the changes in the gonad tissue weighting factor, 66% believed additional emphasis should be placed on protecting organs and tissues with higher tissue weighting factors. The vast majority (87%) believed lead shielding is not the primary dose reduction strategy, with 82% agreeing that lead shielding may interfere with the AEC. CONCLUSION: This study identifies a perception that lead protection may still play a role in patient protection, particularly for children and pregnant patients. However, it is not considered the primary mechanism of protection. More specific guidance and information are needed to incorporate the guidance for radiographers into working practice, improving patient care. IMPLICATIONS FOR PRACTICE: Lead shielding remains a tool for radiation protection in particular examinations, however, its role has diminished in clinical practice. RECOMMENDATIONS: Additional research is required into the number of repeat x-rays associated with the use of lead shielding and the actual dose saving for shielding outside the field of view. Additional education and specific clarification on when to use and not use lead contact shielding is required.

The effect of breast shielding outside the field of view on breast entrance surface dose in axial X-ray examinations: a phantom study.

PURPOSE: The purpose of this study was to evaluate the effect of outside-field-of-view (FOV) lead shielding on the entrance surface dose (ESD) of the breast on an anthropomorphic X-ray phantom for a variety of axial skeleton X-ray examinations. METHODS: Using an anthropomorphic phantom and radiation dosimeter, the ESD of the breast was measured with and without outside-FOV shielding in anterior-posterior (AP) abdomen, AP cervical spine, occipitomental 30° (OM30) facial bones, AP lumbar spine, and lateral lumbar spine radiography. The effect of several exposure parameters, including a low milliampere-seconds technique, grid use, automatic exposure control use, wraparound lead (WAL) use, trolley use, and X-ray table use, on the ESD of the breast with and without outside-FOV shielding was investigated. The mean ESD (µSv) and standard deviation for each radiographic protocol were calculated. A one-tailed Student's t-test was carried out to evaluate whether ESD to the breast was reduced with the use of outside-FOV shielding. RESULTS: A total of 920 breast ESD measurements were recorded across the different protocol parameters. The largest decrease in mean ESD of the breast with outside-FOV shielding was 0.002 µSv (P = 0.084), recorded in the AP abdomen on the table with a grid, OM30 on the table with a grid, OM30 standard protocol on the trolley, and OM30 on the trolley with WAL protocols. This decrease was found to be statistically non-significant. CONCLUSION: This study found no significant decrease in the ESD of the breast with the use of outside-FOV shielding for the AP abdomen, AP cervical spine, OM30 facial bones, AP lumbar spine, or lateral lumbar spine radiography across a range of protocols.

Cumulative Radiation Dose from Medical Imaging in Children with Congenital Heart Disease: A Systematic Review.

Children with congenital heart disease are exposed to repeated medical imaging throughout their lifetime. Although the imaging contributes to their care and treatment, exposure to ionising radiation is known to increase one's lifetime attributable risk of malignancy. A systematic search of multiple databases was performed. Inclusion and exclusion criteria were applied to all relevant papers and seven were deemed acceptable for quality assessment and risk of bias assessment. The cumulative effective dose (CED) varied widely across the patient cohorts, ranging from 0.96 mSv to 53.5 mSv. However, it was evident across many of the included studies that a significant number of patients were exposed to a CED >20 mSv, the current annual occupational exposure limit. Many factors affected the dose which patients received, including age and clinical demographics. The imaging modality which contributed the most radiation dose to patients was cardiology interventional procedures. Paediatric patients with congenital heart disease are at an increased risk of receiving an elevated cumulative radiation dose across their lifetime. Further research should focus on identifying risk factors for receiving higher radiation doses, keeping track of doses, and dose optimisation where possible.

Efficacy of Artificial Intelligence in the Categorisation of Paediatric Pneumonia on Chest Radiographs: A Systematic Review.

This study aimed to systematically review the literature to synthesise and summarise the evidence surrounding the efficacy of artificial intelligence (AI) in classifying paediatric pneumonia on chest radiographs (CXRs). Following the initial search of studies that matched the pre-set criteria, their data were extracted using a data extraction tool, and the included studies were assessed via critical appraisal tools and risk of bias. Results were accumulated, and outcome measures analysed included sensitivity, specificity, accuracy, and area under the curve (AUC). Five studies met the inclusion criteria. The highest sensitivity was by an ensemble AI algorithm (96.3%). DenseNet201 obtained the highest level of specificity and accuracy (94%, 95%). The most outstanding AUC value was achieved by the VGG16 algorithm (96.2%). Some of the AI models achieved close to 100% diagnostic accuracy. To assess the efficacy of AI in a clinical setting, these AI models should be compared to that of radiologists. The included and evaluated AI algorithms showed promising results. These algorithms can potentially ease and speed up diagnosis once the studies are replicated and their performances are assessed in clinical settings, potentially saving millions of lives.
