Value of MRI in the cervical spine imaging series of trauma patients: A state-of-the-art review.

INTRODUCTION: Clinical decision protocols for evaluation and assessment of traumatic cervical spine injuries (TCSI) lean more towards the use of CT imaging. Investigation with MRI is therefore considered unnecessary following negative CT findings according to some local protocols. This review aims to explore what benefits MRI may offer in the clinical management of TCSI patients. METHODS: A systematic search of the literature was conducted in the following databases: AMED, CINAHL, EMBASE and MEDLINE using defined key terms and synonyms optimised for each database. The eligible articles were subjected to data extraction and thematic synthesis. RESULTS: The initial electronic search yielded 2527 articles. Of these, 15 articles remained following the application of a pre-defined inclusion criteria and full-text assessment. Four themes (mechanism of injury, type of patient, injuries detected on MRI, significance of injuries detected on MRI) were developed relating to the usage and value of MRI in the management of CSI. DISCUSSION: Our findings indicate that MRI may be very valuable in some situations for the evaluation of TCSI, however, its usage must be cautiously considered on a case-by-case basis in light of additional clinical benefit, patient safety and resource availability following a normal CT scan or in conjunction with CT or projection radiography where appropriate. IMPLICATIONS FOR PRACTICE: MRI may serve as a confirmatory test in the management pathway of TCSI based on individual clinical needs. Consideration for key limitations (e.g., patients' cooperation) and accessibility challenges (e.g., cost) against the clinical benefit to the patient must be noted. Development of centre-specific policies from standard trauma imaging protocols may be essential for the timely management of TCSI.

Assessment of diagnostic radiographers' knowledge of work-related health problems and associated effects: A multicentre study in Ghana.

INTRODUCTION: Work-related health problems (WRHPs) are health conditions peculiar to a group of people or occupations including radiography in a specific work setting. These WRHPs occur as a result of prevailing work conditions which predispose workers to risks of physical or psychological distress. AIM: This study assessed the knowledge of WRHPs among practicing radiographers in Ghana and evaluated the sources, causes, effects and preventive measures of WRHPs. METHODS: A prospective cross-sectional design incorporating a quantitative data collection approach was used. A questionnaire was used to assess the knowledge and evaluate the effects of WRHPs among two cohorts of 31 practicing radiographers at a regional hospital (RH) and a teaching hospital (TH). RESULTS: An average score of 4.2 (SD = 0.4) out of 5 (84.8%) obtained on the knowledge scale indicated very good knowledge of WRHPs among the radiographers. Physical work demands, ergonomic issues, increased workload and stress levels on on-duty radiographers due to sick absence by colleagues, large numbers of daily cases, and extra work without incentives were reported as WRHPs effects mostly experienced by the radiographers. The study also showed no significant difference between gender groups (p = 0.313), years of professional practice experience level (p = 0.319), and academic qualifications (p = 0.287) on knowledge of WRHPs. CONCLUSION: Radiographers working in some referral and teaching hospitals in Ghana demonstrated very good knowledge of WRHPs and identified several effects of WRHPs on professional practice. IMPLICATION FOR PRACTICE: The study concludes that WRHPs predispose radiographers to adverse health conditions, and administrative protocols are required to prevent or mitigate the burden.

COVID-19 vaccine hesitancy concerns: Findings from a Ghana clinical radiography workforce survey.

INTRODUCTION: Vaccination is a key global strategy to mitigate the clinical impact of the COVID-19 virus. As part of local efforts to manage the outbreak, the government of Ghana announced its intention to vaccinate its population starting with essential and high-risk workers including radiographers. However, there were reports of hesitance to receiving the vaccine among the radiography workforce. This study was undertaken prior to the intended vaccination exercise to assess the willingness and concerns of radiographers to undergo the COVID-19 vaccination and to suggest recommendations to improve the vaccine uptake. METHODS: An ethically-approved online survey strategy was employed for this cross-sectional study conducted between 24th-28th February 2021. The survey employed quantitative questions and open text response options. Quantitative and open text responses were analysed using statistical and thematic analyses, respectively. RESULTS: There were 108 responses (response rate of 46.3%). The majority (n = 64, 59.3%) were willing to have the vaccine, however, some (n = 44, 40.7%) were not. The main reason behind their willingness to have the vaccine was its ability to reduce the spread of infections and lower mortality (n = 35, 54.7%). However, doubts about the vaccine's efficacy and side effects (n = 26, 56.8%), conspiracy theory concerns about its effects on the Ghanaian race (n = 4, 9.1%), and fertility concerns (n = 2, 4.5%) were some reasons for their hesitance to receive the vaccine. The open text commentary further revealed that the vaccine was thought of as a lifesaving medication, however, clinical safety concerns, lack of education/information and religious beliefs were affecting peoples' willingness to be vaccinated. CONCLUSION: Our findings demonstrate the need for an urgent public health educational intervention to address the COVID-19 vaccine hesitancy concerns raised by radiographers to help increase the vaccine uptake. IMPLICATION FOR PRACTICE: The study provides pertinent information to improve COVID-19 vaccine uptake among radiographers to limit the spread of infections.

Impact of artificial intelligence on clinical radiography practice: Futuristic prospects in a low resource setting.

OBJECTIVES: Current trends in clinical radiography practice include the integration of artificial intelligence (AI) and related applications to improve patient care and enhance research. However, in low resource countries there are unique barriers to the process of AI integration. Using Ghana as a case study, this paper seeks to discuss the potential impact of AI on future radiographic practice in low-resource settings. The opportunities, challenges and the way forward to optimise the potential benefits of AI in future practice within these settings have been explored. KEY FINDINGS: Some of the barriers to AI integration into radiographic practice relate to lack of regulatory and legal policy frameworks and limited resource availability including unreliable internet connectivity and low expert skillset. CONCLUSION: These barriers notwithstanding, AI presents a great potential to the growth of medical imaging and subsequently improving quality of healthcare delivery in the near future. For example, AI-enabled radiographer reporting has a potential to improving quality of healthcare, especially in low-resource settings like Ghana with an acute shortage of radiologists. In addition, futuristic AI-enabled advancements such as synthetic cross-modality transfer where images from one modality are used as a baseline to generate a corresponding image of another modality without the need for additional scanning will be of particular benefit in low-resource settings. IMPLICATIONS FOR PRACTICE: The urgent need for inclusion of AI modules for the training of the radiographer of the future has been suggested. Recommendations for development of AI strategies by national societies and regulatory bodies will harmonise the implementation efforts. Finally, there is need for collaboration between clinical practitioners and academia to ensure that the future radiography workforce is well prepared for the AI-enabled clinical environment.

PATIENT DOSE ASSESSMENT AND OPTIMISATION OF PELVIC RADIOGRAPHY WITH COMPUTED RADIOGRAPHY SYSTEMS.

Digital radiography systems can reduce radiation dose, this capability was harnessed to explore dose and image quality (IQ) optimisation strategies. Entrance surface dose (ESD), effective dose (ED) and organ doses were determined by the indirect method for patients undergoing pelvic anteroposterior X-ray examinations with computed radiography systems. The IQ of patients' radiographs was assessed in terms of signal-to-noise ratio (SNR). An anthropomorphic phantom was exposed with varying tube potential (kVp), tube current-time product (mAs), and focus-to-detector distance (FDD) to determine phantom-entrance dose for the optimisation studies. SNR of each phantom radiograph was determined. Patients' mean ESD of 2.38 ± 0.60 mGy, ED of 0.25 ± 0.07 mSv and SNR of 8.5 ± 2.2 were obtained. After optimisation, entrance dose was reduced by 29.2% with 5 cm increment in FDD, and 5 kVp reduction in tube potential. kVp and/or mAs reduction with an increment in FDD reduced entrance dose without adversely compromising radiographic-IQ.

The global impact of the COVID-19 pandemic on clinical radiography practice: A systematic literature review and recommendations for future services planning.

INTRODUCTION: Worldwide, reports and experiences indicate that there has been extensive re-organisation within diagnostic imaging and radiotherapy departments in response to the COVID-19 pandemic. This was necessary due to changes in workload and working practice guidelines that have evolved during the pandemic. This review provides a comprehensive summary of the global impact of the COVID-19 pandemic on radiography practice, service delivery and workforce wellbeing. METHODS: A systematic review methodology was adopted to obtain data from primary studies of qualitative, quantitative, and mixed methods designs from databases (PubMed, Science Direct, Cumulative Index of Nursing and Allied Health Literature [CINAHL], and SCOPUS: all 2020 to present). The included articles were subjected to information extraction and results-based convergent synthesis. RESULTS: The electronic database search yielded 10,420 articles after removal of duplicates. Of these, 31 articles met the final inclusion criteria with some (n = 8) fully focussed on radiotherapy workforce and service delivery. The pandemic impact on radiography practice is broadly themed around: training, communication, and information dissemination; infrastructure, technology, and clinical workflow; and workforce mental health and well-being. CONCLUSION: Globally, most radiographers received inadequate training for managing COVID-19 patients during the initial acute phase of the pandemic. Additionally, there were significant changes to clinical practice, working patterns and perceived increase in workload due to surges in COVID-19 patients and the consequent strict adherence to new infection protocols. These changes, coupled with fear emanating from the increased risk of the workforce to contracting the infection, contributed to anxiety and workplace-related stress during the pandemic. IMPLICATIONS FOR PRACTICE: Local pandemic response strategies must be appropriately developed from standard protocols in readiness for safe clinical practice and well-being management training of practitioners.

The integration of artificial intelligence in medical imaging practice: Perspectives of African radiographers.

INTRODUCTION: The current technological developments in medical imaging are centred largely on the increasing integration of artificial intelligence (AI) into all equipment modalities. This survey assessed the perspectives of African radiographers on the integration of AI in medical imaging in order to offer unique recommendations to support the training of the radiography workforce. METHODS: An exploratory cross-sectional online survey of radiographers working within Africa was conducted from March to August 2020. The survey obtained data about their demographics and perspectives on AI implementation and usage. Data obtained were analysed using both descriptive and inferential statistics. RESULTS: A total of 1020 valid responses were obtained. Majority of the respondents (n = 883,86.6%) were working in general X-ray departments. Of the respondents, 84.9% (n = 866) indicated that AI technology would improve radiography practice and quality assurance for efficient diagnosis and improved clinical care. Fear of job losses following the implementation of AI was a key concern of most radiographers (n = 625,61.3%). CONCLUSION: Generally, radiographers were delighted about the integration of AI into medical imaging, however; there were concerns about job security and lack of knowledge. There is an urgent need for stakeholders in medical imaging infrastructure development and practices in Africa to start empowering radiographers through training programmes, funding, motivational support, and create clear roadmaps to guide the adoption and integration of AI in medical imaging in Africa. IMPLICATION FOR PRACTICE: The current study offers unique suggestions and recommendations to support the training of the African radiography workforce and others in similar resource-limited settings to provide quality care using AI-integrated imaging modalities.

Cognisance of magnetic resonance imaging-induced vertigo and supported care: A study among a cohort of MRI radiographers in a country in West Africa.

INTRODUCTION: Magnetic resonance imaging (MRI) can induce vertigo in patients undergoing such examinations. The severity of the vertigo is thought to increase with higher magnetic field strengths and could cause a patient to fall. The study assessed the awareness levels on MRI-induced vertigo among a cohort of MRI radiographers and their perspectives on the care that should be administered to patients post MRI examinations. METHODS: The study utilized a quantitative cross-sectional research design and a questionnaire. Out of a total of 40 MRI-radiographers identified nationwide, 31 participated in the study. Statistical Package for Social Sciences v.21.0 was used to analyse the data. RESULTS: Most participants (n = 21, 67.7%) were aware of MRI-induced vertigo. Many knew that patients (able and weaker) need to be assisted off the couch (n = 28, 90.3%) and escorted to the changing rooms post MRI examinations (n = 31,100%). There were statistically significant associations between the size of magnetic field strength used by the participants and their level of awareness about MRI-induced vertigo (r = 0.691, p = 0.003), appreciation of the needed support for patients post MRI examinations (r = 0.530, p = 0.041) and the frequency of occurrence of MRI-induced vertigo among their patients (r = 0.530, p = 0.001). CONCLUSION: The radiographers were mostly cognisant of MRI-induced vertigo and the supported care they were supposed to administer to their patients. The size of magnetic field strength used by the participants correlated with their level of awareness about MRI-induced vertigo and their appreciation of the needed support for patients post MRI examinations. IMPLICATION FOR PRACTICE: The study highlights the need for a refresher training to expand the knowledge-base of a few of the radiographers who were not very cognisant about MRI-induced vertigo.

Impact of the COVID-19 pandemic on clinical radiography practice in low resource settings: The Ghanaian radiographers' perspective.

INTRODUCTION: The COVID-19 pandemic has altered the professional practice of all healthcare workers, including radiographers. In the pandemic, clinical practice of radiographers was centred mostly on chest imaging of COVID-19 patients and radiotherapy treatment care delivery to those with cancer. This study aimed to assess the radiographers' perspective on the impact of the pandemic on their wellbeing and imaging service delivery in Ghana. METHODS: A cross-sectional survey of practising radiographers in Ghana was conducted online from March 26th to May 6th, 2020. A previously validated questionnaire that sought information regarding demographics, general perspectives on personal and professional impact of the pandemic was used as the research instrument. Data obtained was analysed using Microsoft Excel® 2016. RESULTS: A response rate of 57.3% (134/234) was obtained. Of the respondents, 75.4% (n = 101) reported to have started experiencing high levels of workplace-related stress after the outbreak. Three-quarters (n = 98, 73.1%) of respondents reported limited access to any form of psychosocial support systems at work during the study period. Half (n = 67, 50%) of the respondents reported a decline in general workload during the study period while only a minority (n = 18, 13.4%) reported an increase in workload due to COVID-19 cases. CONCLUSION: This national survey indicated that majority of the workforce started experiencing coronavirus-specific workplace-related stress after the outbreak. Albeit speculative, low patient confidence and fear of contracting the COVID-19 infection on hospital attendance contributed to the decline in general workload during the study period. IMPLICATIONS FOR PRACTICE: In order to mitigate the burden of workplace-related stress on frontline workers, including radiographers, and in keeping to standard practices for staff mental wellbeing and patient safety, institutional support structures are necessary in similar future pandemics.

PRELIMINARY STAFF DOSE ASSESSMENT FOR COMMON FLUOROSCOPY GUIDED PROCEDURES AT KORLE-BU TEACHING HOSPITAL, ACCRA, GHANA.

Preliminary studies on effective and eye lens doses of six Radiologists, four Cardiologists have been conducted for a period of 3 months. Electronic dosemeters positioned under and over lead apron of staff were used for the dosimetry. The estimated effective dose per month to Cardiologist and Radiologist were 0.01-0.07 mSv and 0.03-0.14 mSv, respectively. The estimated eye lens doses per month to Cardiologists and Radiologists were also 0.15-0.30 mSv and 0.53-3.39 mSv, respectively. The effective doses per month to staff were below the ICRP acceptable limit of 1.67 mSv/month but the upper limit of the range of estimated eye lens dose exceeded the ICRP acceptable limit by a factor of 2. Regular use of protective goggles and consistent eye lens dose monitoring is encouraged at the hospital for dose optimization.

Running water sound technique in contrast-based voiding cystourethrogram: A case-control study.

BACKGROUND: An intervention that can reduce the patient void time during a voiding cystourethrogram (VCUG) procedure can reduce the total radiation dose to the patient. This is because a delay in voiding leads to a high number of intermittent screenings to monitor if voiding occurs. This study assessed the impact of running-water sound (RWS) upon patients' voiding parameters and fluoroscopy screening times during VCUG examinations among children and adults. MATERIALS AND METHODS: A case-control study involving 252 patients was undertaken which consisted two groups (control and test) of adults and children. The test groups underwent VCUG with RWS technique while the control groups underwent the procedure normally. T-test was used to compare the study parameters between the two groups and a p-value less than 0.05 was interpreted as significant. RESULTS: The mean screening times (s) for children who underwent VCUG with and without RWS were 17.15 ± 2.5s and 30.61 ± 5.1s respectively (p = 0.0024). For adults, the RWS technique recorded a mean screening time of 37.36 ± 4.4s while the non-RWS procedures recorded 49.80 ± 5.2s (p = 0.001). The participants who received RWS intervention also felt the urge to void earlier than those who received no RWS intervention. The differences were also statistically significant for both children and adults. CONCLUSION: The study being one of the first in this subject area indicates that the application of RWS technique induces early urge of iodinated-contrast voiding, and reduces voiding and fluoroscopy screening times during VCUG among children and adults. This simple technique can potentially enhance current practice.
