Rationale And Objectives:
As the use of magnetic resonance imaging (MRI) continues to grow, it is essential for radiology trainees to develop the confidence and expertise to interpret MRI studies effectively. However, residents have reported inadequate MRI training, often citing limited case volume as a key contributor. This study aims to evaluate the relationship between MRI case volume and confidence in MRI interpretation among diagnostic radiology residents, and to identify factors influencing both case volumes and confidence.
Materials And Methods:
A retrospective review of MRI case volume between 2018 and 2023 and online survey was performed among current residents and recent graduates of a Canadian diagnostic radiology residency program.
Results:
There was a significant strong positive association between current residents' MRI case volume and confidence in MRI interpretation (r = 0.9, P < 0.001, 95% CI 0.7-1.0), and a trend toward a moderate positive correlation among recent graduates (r = 0.4, P = 0.09, 95% CI -0.08-0.7). Participants reported structured MRI rotations, resident proactivity, and staff interest and availability for teaching as key factors influencing resident MRI case volume and confidence in MRI interpretation.
Conclusion:
Increased MRI case volumes are associated with greater confidence in MRI interpretation among diagnostic radiology residents. Additional factors, such as dedicated subspeciality MRI rotations, resident initiative, and staff engagement, also play a crucial role.
