Background

The aim of this study was to describe the proficiency of ChatGPT (GPT-4) on certification style exams from the Canadian Association of Medical Radiation Technologists (CAMRT), and describe its performance across multiple exam attempts.

Methods

ChatGPT was prompted with questions from CAMRT practice exams in the disciplines of radiological technology, magnetic resonance (MRI), nuclear medicine and radiation therapy (87-98 questions each). ChatGPT attempted each exam five times. Exam performance was evaluated using descriptive statistics, stratified by discipline and question type (knowledge, application, critical thinking). Light's Kappa was used to assess agreement in answers across attempts.

Results

Using a passing grade of 65 %, ChatGPT passed the radiological technology exam only once (20 %), MRI all five times (100 %), nuclear medicine three times (60 %), and radiation therapy all five times (100 %). ChatGPT's performance was best on knowledge questions across all disciplines except radiation therapy. It performed worst on critical thinking questions. Agreement in ChatGPT's responses across attempts was substantial within the disciplines of radiological technology, MRI, and nuclear medicine, and almost perfect for radiation therapy.

Conclusion

ChatGPT (GPT-4) was able to pass certification style exams for radiation technologists and therapists, but its performance varied between disciplines. The algorithm demonstrated substantial to almost perfect agreement in the responses it provided across multiple exam attempts. Future research evaluating ChatGPT's performance on standardized tests should consider using repeated measures.

Background

The Mammography Quality Standards Act (MQSA) has significant impact on providing high-quality mammography services for the early detection of breast cancer. MQSA emphasizes quality assurance, regulatory compliance, and patient safety. It guides technological integration, ensuring uniform quality across the United States of America (USA). This review synthesizes key MQSA information, analysing compliance, and facilitating policy discussions for improvements, aiming to inspire further policy research in cancer screening by adopting MQSA's success factors.

Methods

The review spanned 1997 to 2023, adhering to Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Databases like PubMed, ScienceDirect, and Google Scholar were searched for relevant literature. Selection criteria covered English-language journals, US Food and Drug Administration (FDA) guidelines, and professional organizational standards, revealing key aspects of MQSA and breast cancer diagnostics in the USA.

Results and Discussion

MQSA's legislative aspects guarantee the effectiveness of regulations for high-quality mammography. It addresses technology, emphasizes inspections, and balances compliance with healthcare burdens. Procedural guidelines prioritize patient outcomes, minimize errors, and address access disparities. Regular updates are crucial to align screening services with technological changes, maintaining safety and accuracy nationwide.

Conclusion

The FDA's collaboration with stakeholders, including medical specialists and patient advocacy groups, has contributed to crucial legislative aspects of MQSA. The accuracy of mammography screenings has significantly improved by MQSA's installation of stringent quality and regulatory standards. Compliance with MQSA guidelines led to higher accuracy, safety, and better detection rates. Ongoing efforts must aim to refine guidelines, address emerging challenges, and optimize breast cancer detection.

Introduction/Background

Effective communication is critical in all healthcare professions, including medical imaging. This is demonstrated across the professional capability requirements outlined by regulatory bodies that represent medical radiation practitioners around the world. Thus, it is imperative that university curricula provide students with opportunities to develop their communication skills to ensure graduates are prepared to deliver high-quality person-centred care (PCC).

The aim of this educational perspective paper is to discuss an interprofessional collaboration between academics from medical imaging and a linguist from the Faculty of Medicine, Nursing and Health Sciences' health communication unit to develop and deliver a pre-clinical communication skills program for undergraduate medical imaging students at Monash University. This innovative program aims to address the unique communication challenges encountered during medical imaging examinations.

Discussion

Medical imaging programs tend to use a combination of lectures, role-play and structured workshops to teach communication skills to undergraduate students. These are normally run by medical imaging academics who have significant clinical experience as well as tacit intuitive understanding of communication challenges. This intuitive knowledge can be challenging to articulate to novice learners. In comparison, a linguist is an expert in the use and form of language in context, and can collaborate with medical imaging academics to support students in developing their understanding of communication as a tool for use in caring and compassionate practice as part of a PCC approach. This paper highlights an interprofessional collaboration between medical imaging academics and a linguist to develop and deliver an integrated communication skills program at Monash University, bringing together the expertise of both fields to support medical imaging students in effectively communicating with patients in the clinical context.

Conclusion

The interprofessional collaboration between medical imaging academics and a linguist at Monash University shows early promise. Our collaborative pre-clinical communication skills curriculum development and delivery pioneers an innovative method within the medical imaging curriculum which integrates best practice from both medical imaging and linguistic fields.

Introduction

Subarachnoid hemorrhage (SAH) is a critical medical condition associated with high morbidity and mortality rates. Timely and accurate diagnosis is crucial for optimal patient outcomes. Cranial computed tomography (CT), computed tomography angiography (CTA), and digital subtraction angiography (DSA) are commonly used imaging modalities for diagnosing SAH, but their comparative diagnostic efficacy remains debated.

Methods

A systematic review and meta-analysis was conducted to evaluate the diagnostic performance of cranial CT, CTA, and DSA in identifying SAH. PubMed, Google scholar, Cochrane Library databases were searched for relevant studies published up to January 2024. Pooled sensitivity, specificity, and the summary receiver operating characteristic (SROC) curve were calculated using Review Manager 5.4.

Results

A total of 31 studies involving 10,287 patients were included in the analysis. The pooled sensitivity of cranial CT for detecting SAH was 94.7 % (95 % Confidence Interval, CI) with a specificity of 98.3 % (95 % CI). CTA demonstrated a pooled sensitivity of 94.1 % (95 % CI) and specificity of 93.4 % (95 % CI). DSA showed a pooled sensitivity of 87.7 % (95 % CI) and specificity of 95.8 % (95 % CI). The SROC curve demonstrated discriminatory ability for all modalities.

Conclusion

Cranial CT, CTA, and DSA are valuable imaging modalities for diagnosing SAH, with high sensitivity and specificity. Cranial CT serves as an initial screening tool, while CTA offers superior sensitivity in detecting aneurysmal SAH. DSA remains essential in specific clinical scenarios. Further prospective studies are needed to validate these findings and refine diagnostic guidelines for SAH.

The Educational Perspective synthesizes the literature on the self-relevance effect, scaffolding, active learning, and metacognitive strategies to elucidate their role in promoting student engagement and success. The article offers recommendations to address the observed challenges, including creating scenario-based eLearning modules, providing immediate feedback and reflection opportunities, and incorporating gamification elements. These strategies aim to enrich asynchronous learning experiences, empowering radiology students to effectively adapt to changing educational landscapes and achieve optimal learning outcomes.

Purpose

Volumetric modulated arc therapy (VMAT) has allowed for dose escalation and a decrease in radiation-induced toxicities for a variety of treatment sites, including spinal metastases. This article will compare the dosimetric impacts on normal lung tissue in patients treated with both VMAT and conventional treatment to the thoracic spine and determine if any significant difference exists among patient reported Edmonton Symptom Assessment System (ESAS) scores.

Methods

This retrospective quality assurance study identified 288 patients who received palliative radiotherapy to the thoracic spine using VMAT or conventional planning techniques with various palliative dose fractionation schemes. V5 lung dose levels, treated planning target volume (PTV) cord length, patient-reported ESAS scores at the time of radiation oncology consultation, 3 months’ post-treatment, and 6 months’ post-treatment were analyzed. All symptoms on the ESAS survey were investigated, but shortness of breath (SOB) scores were the main focus of this study. Date of death for each patient was also included for analysis.

Results

Patients treated with a VMAT technique had significantly higher V5 lung dose levels compared to those treated conventionally (right lung: p = 1.67e-14; left lung: p = 1.33e-6). Despite this, no significant differences were observed for SOB scores at all time points between groups and conventionally treated patients reported significantly worse pain, tiredness, depression, and wellbeing scores. A moderate correlation was observed between PTV length and nausea, SOB, appetite, and drowsiness scores in the VMAT group. Treatment technique was not found to have a significant impact on patient lifespan.

Conclusions

Despite higher V5 lung dose levels associated with a VMAT technique, no significant differences were found in patient-reported ESAS scores compared to patients treated with conventional techniques. This demonstrates that palliation of thoracic spinal metastases is feasible and safe using a VMAT technique.

Introduction

Policymakers wish to extend access to medical records, including medical imaging. Appreciating how patients might review radiographs could be key to establishing future training needs for healthcare professionals and how image sharing could be integrated into practice.

Method

A pilot study in the UK using a survey was distributed to adult participants via the online research platform Prolific. All subjects were without prior professional healthcare experience. Participants reviewed ten radiographs (single projection only) and were asked a two-stage question. Firstly, if the radiograph was ‘normal’ or ‘abnormal’ and secondly, if they had answered ‘abnormal’, to identify the abnormality from a pre-determined list featuring generic terms for pathologies.

Results

Fifty participants completed the survey. A mean of 65.8 % of participants were able to correctly identify if radiographs were normal or abnormal. Results in relation to the identification of a pathology were not as positive, but still notable with a mean of 46.4 % correctly identifying abnormalities. Qualitative data demonstrated that members of the public are enthralled with reviewing radiographs and intrigued to understand their performance in identifying abnormalities.

Conclusion

In the pilot, members of the public could identify if a radiograph is normal or abnormal to a reasonable standard. Further detailed interpretation of images requires supportive intervention. This pilot study suggests that patients can participate in image sharing as part of their care. Image sharing may be beneficial to the therapeutic relationship, aiding patient understanding and enhancing consultations between healthcare professional and patient. Further research is indicated.
