Abstract

Purpose: To establish the effect on diagnostic confidence of a simulation setting, in which radiologists re-interpret anonymized pediatric MRI cases.

Materials: In this IRB-approved study, participants completed surveys rating confidence before and after interpreting 10 MRI cases for suspected appendicitis in children.

Results: 18 radiologists (4 faculty, 5 fellows, and 9 residents) correctly identified an average of 7.44 cases (range 5-9). Self-described confidence regarding technique and interpretation increased from 2.0 (SD 0.77) and 2.33 (SD 0.69) to 2.83 (SD 0.71) and 2.94 (SD 0.73), respectively.

Conclusion: Simulated interpretation of pediatric MRI in suspected appendicitis results in increased self-describe confidence without requiring additional capital/equipment expenses.
