Knowledge, attitudes, and practices related to breast cancer screening among female Jordanian university employees: A cross-sectional study.

INTRODUCTION: To improve participation in breast screening programs, the level of knowledge about BC, attitudes, and practices of women in different sections of society must be understood. This study aimed to measure the level of knowledge of BC risk factors, signs and symptoms and determine current mammography practices among female employees at Jordanian universities. METHODS: A cross-sectional descriptive study was conducted on female employees at Jordanian government universities. Data was collected using a structured questionnaire that included: sociodemographic characteristics, knowledge of BC risk factors, knowledge of BC symptoms and knowledge, attitude and practice of mammography as an early detection method. RESULTS: A total of 362 participants completed the questionnaire. Overall, 174 scored ≥50% correct answers regarding BC risk factors, while 231 scored ≥50% correct answers regarding BC signs and symptoms. Half of the participants (n = 184, 50.8%) understood mammography to be an early BC detection method. Among those participants, 95 (51.6%) were eligible for screening and 39 (21.2%) had had a previous mammogram. The main reason for not engaging in mammography was the absence of BC signs and symptoms (37.2%). Profession, educational level and family history of BC were associated with increased knowledge of BC risk factors, signs and symptoms (p = 0.01). Lecturers in medical faculties exhibited the highest level of knowledge about mammography compared to participants in other professions (p = 0.02). CONCLUSION: Only 79 participants had good to excellent knowledge about BC. Participants' profession was the major indicator for awareness of BC and mammography as an early detection method. IMPLICATIONS FOR PRACTICE: The findings of this study reinforce the importance of providing BC educational programs for university employees in Jordan to increase awareness of BC and mammography.

Australian radiographers' awareness of cardiac implantable electronic devices (CIEDs) in mammographic imaging.

INTRODUCTION: Women presenting for mammography occasionally have pacemakers or other cardiac-implantable electronic devices (CIEDs) in situ. This research investigates Australian radiographers' awareness of CIEDs in the diagnostic and screening settings. METHODS: A survey of radiographers with mammography experience in Australia was conducted using SurveyMonkey™. Respondents were asked if they could confidently identify images of devices and whether they had imaged them mammographically. A Chi-squared test of independence was used to compare the association between demographics and CIED awareness. A value of p < 0.05 was deemed statistically significant. RESULTS: There were 220 valid responses. All CIED types had been imaged. Most respondents had imaged a pacemaker (94.5%) and implantable cardioverter-defibrillator (ICD) (85.6%), compared to the three different implantable loop recorders (ILRs) (ILR-1: 63.4%; ILR-2: 14.1%; and IRL-3: 26.9% and the emerging subcutaneous ICDs (S-ICDs) (11.9%). Most respondents felt confident identifying the pacemaker (95%) and the ICD (86.1%). Only 19.4% of respondents could confidently identify the emerging S-ICD. CONCLUSION: A lack of awareness of new and emerging devices may impact approaches to imaging and present significant risk to patients. The lack of studies comprehensively describing devices and their mammographic appearance to support radiographers' knowledge and awareness highlights an urgent need to progress research in this area. IMPLICATIONS FOR PRACTICE: As a part of continuing professional development, radiographers performing mammography must ensure they remain up to date with current and emerging technology, including CIEDs. This study has identified a lack of awareness of the different types of CIEDs currently being implanted and imaged, which may translate to unsafe imaging practices. There is an urgent need for further education to bridge this knowledge gap and ensure the safety of practice in imaging women with CIEDs. FOOTLINE: Mammography: CIED Imaging.

ChatGPT in medical imaging higher education.

INTRODUCTION: Academic integrity among radiographers and nuclear medicine technologists/scientists in both higher education and scientific writing has been challenged by advances in artificial intelligence (AI). The recent release of ChatGPT, a chatbot powered by GPT-3.5 capable of producing accurate and human-like responses to questions in real-time, has redefined the boundaries of academic and scientific writing. These boundaries require objective evaluation. METHOD: ChatGPT was tested against six subjects across the first three years of the medical radiation science undergraduate course for both exams (n = 6) and written assignment tasks (n = 3). ChatGPT submissions were marked against standardised rubrics and results compared to student cohorts. Submissions were also evaluated by Turnitin for similarity and AI scores. RESULTS: ChatGPT powered by GPT-3.5 performed below the average student performance in all written tasks with an increasing disparity as subjects advanced. ChatGPT performed better than the average student in foundation or general subject examinations where shallow responses meet learning outcomes. For discipline specific subjects, ChatGPT lacked the depth, breadth, and currency of insight to provide pass level answers. CONCLUSION: ChatGPT simultaneously poses a risk to academic integrity in writing and assessment while affording a tool for enhanced learning environments. These risks and benefits are likely to be restricted to learning outcomes of lower taxonomies. Both risks and benefits are likely to be constrained by higher order taxonomies. IMPLICATIONS FOR PRACTICE: ChatGPT powered by GPT3.5 has limited capacity to support student cheating, introduces errors and fabricated information, and is readily identified by software as AI generated. Lack of depth of insight and appropriateness for professional communication also limits capacity as a learning enhancement tool.

Knowledge, attitude, understanding and implementation of evidence-based practice among Jordanian radiographers.

INTRODUCTION: Evidence-based practice (EBP) has gained attention globally from healthcare professionals and researchers. The aim of this study was to assess Jordanian diagnostic radiographers' knowledge, attitude, education/knowledge, and skills related to EBP; and identify specific terms related to EBP. METHODS: A paper-based, self-administered questionnaire with two sections was used. The first section included 11 socio-demographic questions and the second section contained 56 questions regarding EBP categorized under seven distinct subscales. The data were imported into SPSS for analysis. RESULTS: Responses were received from 203 radiographers, most of them 135 (66.5%) aged 21-30 years. The majority of radiographers agreed or strongly agreed that the application of EBP is necessary for radiography practice, and 129 (63.6%) of radiographers learned the foundations of EBP as part of their academic preparation. Less than half of the participants stated that they completely understood the research terminology listed in the survey. Most participants had access to the internet and research databases, 79.3% (n = 161). The majority of participants, 63.1% (n = 128) stated that they always used their personal experience, as a source to make a clinical decision in radiography practice. The most common barrier to the implementation of EBP was insufficient time (63.5%, n = 129). CONCLUSION: This study showed that despite the positive attitude, and beliefs of radiographers toward EBP, and access to information resources, radiographers still need a higher level of confidence in their ability to engage in and implement EBP; including increased education to support the research skills needs to search and interpret publications. IMPLICATIONS FOR PRACTICE: The findings of this study may help inform restructure of the undergraduate radiography curriculum, training programs or other interventions required to promote or facilitate the adoption of EBP in Jordan.

The impacts of vertical off-centring, tube voltage, and phantom size on computed tomography numbers: An experimental study.

INTRODUCTION: This experimental study explored the effect of vertical off-centring on computed tomography (CT) numbers in combination with various tube voltages and phantom sizes for two CT units. METHODS: CIRS Model 062 Electron Density and system performance phantoms were imaged on Siemens Emotion 16-slice CT and GEMINI-GXL scanners, respectively. Uniformity and accuracy were evaluated as a function of vertical off-centring (20, 40, 60, and 80 mm above the gantry isocentre) using different water phantom sizes (18, 20, and 30 cm) and tube voltages (80, 90, 110, 120, 130 and 140 kVp). RESULTS: Vertical off-centring and phantom size accounted for 92% of the recorded variance and the resultant change in CT numbers. The uniformity test recorded maximum changes of 14 and 27.2 HU for peripheral ROIs across the X- and Y-axes for an 80 mm phantom shift above the gantry isocentre on the GEMINI GXL and Siemens scanners, respectively. The absolute CT number differences between the superior and inferior ROIs were 13.7 HU for the 30 cm phantom and 4.8 HU for the 20 cm phantom for 80 mm vertical off-centring. The largest differences were observed at lower tube voltages. CONCLUSIONS: It is essential to highlight the significance of CT number variation in clinical decision-making. Phantom off-centring affected the uniformity of these numbers, which were further impacted by the ROI position in this experimental study. CT number variation was more evident in peripheral phantom areas, lower tube voltages and larger phantom sizes. IMPLICATIONS FOR PRACTICE: CT number is observed to be a variable under certain common conditions. This significantly impacts several applications where clinical decisions depend on CT number accuracy for tissue lesion characterisation.

A review of mammographic lesion localisation and work up imaging in Australia in the digital era.

OBJECTIVES: To investigate the use of coned compression with and without magnification in contemporary Australian digital imaging. To describe lesion localisation techniques used for mammographic work up. KEY FINDINGS: As digital breast tomosynthesis becomes mainstream, the need for coned compression imaging has reduced, however the need for coned compression with fine focus magnification for assessment of microcalcification remains. Adapting film screen lesion localisation techniques to the digital setting is limited by the need for "true size" 1:1 ratio images for ease of measurement. Both the digital ruler and a grid technique can be used as an alternate. CONCLUSION: Advances in image acquisition has evidenced a change in imaging protocols for suspicions lesions within the breast with breast tomosynthesis superseding the need for non-magnified coned compression views of the breast. Adaptation of the approaches to localising these lesions in the digital setting has also been necessary.

Exploring correlations between the breast density of the women of Papua New Guinea and breast cancer risk factors.

INTRODUCTION: Papua New Guinea (PNG), has experienced an increase in breast cancer incidence correlating to the westernisation of the country. Increased breast density is known to increase breast cancer risk. This study investigates if there are any factors unique to the women of PNG that may impact breast density and breast cancer risk. METHOD: A survey was undertaken of 1,161 women who had undergone mammographic imaging at the Pacific International Hospital (PIH). Results were correlated with the five Tabár mammographic parenchymal patterns (TP), recorded for each woman and geographical location, parity, breast size, occupation, marital and menstrual status, smoking and alcohol consumption, hormone replacement therapy (HRT), and exercise. Statistical analysis was undertaken using chi-square test, Fisher's exact test and Odds Ratio (OR). RESULTS: Relationships were identified between TP and parity (p < 0.001), marital status (p < 0.001), smoking (p < 0.001), alcohol intake (p = 0.029) and HRT (p = 0.029). There was no evidence of a relationship between pattern type and geographical location (p = 0.290), breast size (p = 0.592), occupation (p = 0.724), menstruation (p = 0.866) or exercise (p = 0.290). Married women, OR = 0.4004, CI 95% (0.2873-0.5579) and those with higher parity, OR 0.5034, CI 95% (0.3693-0.6862) were half as likely to have increased breast density reducing risk. CONCLUSION: There was no clear relationship across almost all data. Factors associated with increased breast density in PNG included parity, marital status, smoking, alcohol, and HRT use were evidenced in this snapshot of PNG women. Breast cancer risk was shown to be reduced for married women and those with increased parity.

Undergraduate use of medical radiation science mobile applications.

INTRODUCTION: Despite the technologically intense nature of the medical radiation science (MRS) profession, literature specifically supporting the adoption of mobile learning in MRS education is scarce. To this aim, we explored student utilization of and influences for choosing MRS applications (apps, a specific type of mobile learning) within the Bachelor of Medical Radiation Science course at Charles Sturt University (CSU), Australia. Secondary objectives briefly investigated content reliability within selected chosen apps and overall student willingness to embrace this methodology prior to mainstream integration. METHODS: A mixed-method census survey was delivered to 415 enrolled students using the software Survey Monkey to compile responses to 28 questions. Inclusion criteria included students who owned a smartphone or tablet and who used any apps listed on the survey. RESULTS: Among the 97 students who completed the survey, 37% (36/97) freely use MRS apps at least weekly (70%, 21/30), of which anatomy atlases were reported as most popular. Peer recommendation influenced 67% (20/30) of students to choose the MRS apps used. Thirty-seven percent (11/30) of students integrated only one method to check the accuracy of app content prior to download. Students who do not use MRS apps (78%, 76/97) stated they were unaware of this resource; however, 91% (80/88) of the respondents indicated they would use MRS apps if incorporated into the curriculum. CONCLUSION: The majority of CSU students agreed that apps offer a convenient way to engage in a variety of interactive content both in the classroom and on-the-go, using apps most pertinent to their specific curriculum and/or for revision. Students preferred to use MRS apps if integrated as supplemental study tools vetted by the lecturer.

Mammographic parenchymal pattern and breast cancer risk profile of Papua New Guinean women - A baseline study of the screening population.

INTRODUCTION: The aim of this research is to evidence for the first time the breast density of Papua New Guinean (PNG) women as described by mammographic parenchymal patterns (MPPs) and profile breast cancer risk; to examine the relationship of age and MPPs. METHODS: A retrospective analysis of 1161 screening mammograms of women who had undergone imaging at the Pacific International Hospital (PIH) was undertaken. Mammograms were classified into one of five Tabár MPPs; age was recorded in years. Descriptive analysis of the data for pattern distribution and a chi-square test, to test for relationships between age and pattern type were undertaken. RESULTS: The majority (51.42%) of women had Pattern I breasts; Pattern II (30.58%), Pattern III (4.31%), Pattern IV (7.24%), and Pattern V (6.46%). The mean age was 38.8 with a range of 30-80 years; there were no obvious differences in mean age across the categories of patterns. A chi-square test reported no evidence of a relationship between age and pattern type (p-value = 0.504). Pattern V differed from other patterns, with proportionally more women aged over 50 and less aged in their 40s. CONCLUSION: This study sets a baseline for future studies of the MPPs of PNG women, and demonstrated that in this snapshot of PNG women, there is no unique distribution of MPPs and no increased risk of breast cancer based on breast density profile. This result does not help to explain the high incidence of breast cancer in PNG. A more comprehensive study of the PNG screening population is required to validate this study.

Immobilisation in Australian paediatric medical imaging: A pilot study.

AIMS: The primary aim of this study is to document the use of paediatric immobilisation techniques in medical imaging. Secondary aims are to investigate differences between current practice of paediatric and non-paediatric facilities and radiographer gender and to investigate immobilisation protocols. METHODS: A SurveyMonkey link was distributed through the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) newsletter. Radiographer members of ASMIRT were invited to participate. Frequency percentage analysis was undertaken; as the 'frequency of immobilisation' response was on a Likert scale and the ages categorical, a Fisher's exact test could determine dependency. RESULTS: The use of paediatric immobilisation techniques was determined to be related to age. The most commonly used technique in general X-ray was "other people"; in computed tomography, Velcro, verbal reminders and distraction techniques; and in magnetic resonance imaging, sedation and Velcro. A comparison of immobilisation techniques demonstrated that Velcro use in X-ray was dependent on facility (p = 0.017) with paediatric facilities using it up to 17 years. Immobilisation frequency was dependent in 13-17 years (p = 0.035) with paediatric facilities rarely immobilising and non-paediatric facilities never. No dependencies resulted upon comparing genders. Immobilisation frequency was not dependent between protocols or current practice. CONCLUSION: The use of paediatric immobilisation technique is related to age with "other people", sedation, Velcro, verbal reminders and distraction techniques being regularly used. The dependency of Velcro use and immobilisation frequency in 13-17 years is for unknown reasons and further investigation is required. A larger study should be carried out to validate these findings.
