Rationale And Objectives: A Canadian Diagnostic Radiology residency program implemented a competency-based medical education (CBME) curriculum in 2017 (Q-CBME), followed by the national Competence by Design (CBD) model in 2022. These frameworks emphasize progression through frequent assessment of competencies rather than time in training. However, concerns remain that the time burden or "tick-box" mentality in the context of increased assessments may decrease clinical exposure.

Obstruction of the female reproductive tract can occur in multiple locations. This can result in hydrocolpos at the level of the vagina, hydrometra at the level of the uterus, and hydrosalpinx at the level of the uterine tubes, each with their own underlying causes. Identification of relevant anatomy helps localize the obstruction, which facilitates diagnosis and appropriate clinical management.

Bariatric surgery is an effective approach to management of morbid obesity. Given its increasing popularity worldwide, post-operative imaging of patients following bariatric surgery is frequently encountered in clinical practice. In this article we review the physiological principles, normal post-operative anatomy, and imaging appearance of common bariatric procedures (Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and laparoscopic adjustable gastric banding) as well as less common bariatric procedures (including intragastric balloon and biliopancreatic diversion with duodenal switch).

Intraluminal causes of small bowel obstruction (SBO) are less common than mural or extrinsic etiologies. This review categorizes intraluminal causes of SBO into four broad categories to provide a diagnostic framework for radiologic interpretation: 1) ingested contents, 2) bowel stasis, 3) inflammatory causes, and 4) neoplasms. Ingested materials can result in SBO when individual or accumulated contents are too large to pass, such as in the case of foreign bodies or bezoars.

Purpose: Recent competency-based medical education (CBME) implementation within Canadian radiology programs has required faculty to conduct more assessments. The rise of narrative feedback in CBME, coinciding with the rise of large language models (LLMs), raises questions about the potential of these models to generate informative comments matching human experts and associated challenges. This study compares human-written feedback to GPT-3.

Introduction: Since 2022, all Canadian post-graduate medical programs have transitioned to a Competence by Design (CBD) model within a Competency-Based Medical Education (CBME) framework. The CBME model emphasized more frequent, formative assessment of residents to evaluate their progress towards predefined competencies in comparison to traditional medical education models. Faculty members therefore have increased responsibility for providing assessments to residents on a more regular basis, which has associated challenges.

Rationale And Objectives: Queen's University (Kingston, ON, Canada) adopted a competency-based medical education (CBME) curriculum for Diagnostic Radiology residency training in an accelerated manner in 2017, with the curriculum comprised of four stages of training. This article focuses on the final stage (Transition to Practice), during which assessment methods of the new national curriculum (implemented in July 2022) were piloted. This study aims to highlight the challenges and opportunities associated with the implementation of CBME in Diagnostic Radiology training and specific considerations for programs undergoing this curricular transition.

Article Synopsis
  • A 3-week AI workshop was created for radiology residents, incorporating lectures, case studies, and programming examples into their existing training curriculum.
  • The workshop aimed to enhance foundational understanding of AI concepts rather than technical skills, using pre- and post-surveys to assess confidence levels.
  • Results showed that participation significantly increased residents' confidence in AI knowledge, with a high percentage agreeing that the workshop improved their understanding of AI concepts.

Purpose: To assess the diagnostic performance of quantitative and qualitative imaging features of hepatic cirrhosis on CT.

Methods: A single-center retrospective cohort study was performed on all patients who had undergone non-targeted liver biopsy < 3 months following abdominal CT imaging between 2007 and 2020. Histopathology was required as a reference standard for hepatic cirrhosis diagnosis.

Objectives: Systematic program evaluation of the Queen's University diagnostic radiology residency program following transition to a competency-based medical education (CBME) curriculum.

Methods: Rapid Evaluation methodology and the Core Components Framework were utilized to measure CBME implementation. A combination of interviews and focus groups were held with program leaders (n = 6), faculty (n = 10), both CBME stream and traditional stream residents (n = 6), and program staff (n = 2).

Purpose: To assess the impact of radiology review for discordance between pathology results from computed tomography (CT)-guided biopsies versus imaging findings performed before a biopsy.

Materials And Methods: In this retrospective review, which is compliant with the Health Insurance Portability and Accountability Act and approved by the institutional review board, 926 consecutive CT-guided biopsies performed between January 2015 and December 2017 were included. In total, 453 patients were presented in radiology review meetings (prospective group), and the results were classified as concordant or discordant.

Purpose: Postgraduate residency programs in Canada are transitioning to a competency-based medical education (CBME) system. Within this system, resident performance is documented through frequent assessments that provide continual feedback and guidance for resident progression. An area of concern is the perception by faculty of added administrative burden imposed by the frequent evaluations.

Purpose: The Royal College of Physicians and Surgeons of Canada (RCPSC) has mandated the transition of postgraduate medical training in Canada to a competency-based medical education (CBME) model divided into 4 stages of training. As part of the Queen's University Fundamental Innovations in Residency Education proposal, Queen's University in Canada is the first institution to transition all of its residency programs simultaneously to this model, including Diagnostic Radiology. The objective of this report is to describe the Queen's Diagnostic Radiology Residency Program's implementation of a CBME curriculum.

The presence of intralesional fat provides an invaluable tool for narrowing the differential diagnosis for both benign and malignant neoplasms of the abdomen and pelvis. The ability to characterize intralesional fat is further expanded by the ability of magnetic resonance imaging to detect small quantities (intravoxel) of fat. The differential diagnosis of fat-containing lesions arising in the liver is broader than that of many other solid organs.
