Online Interactive Case-Based Instruction in Prostate Magnetic Resonance Imaging Interpretation Using Prostate...

Area of Science:

• Radiology
• Medical Education
• Oncology

Background:

• Prostate magnetic resonance imaging (MRI) interpretation is crucial for cancer diagnosis.
• Standardized reporting systems like Prostate Imaging and Reporting Data System (PI-RADS) aim to improve consistency.
• Effective training for novice readers is essential for accurate prostate MRI assessment.

Purpose of the Study:

• To evaluate the impact of an interactive, case-based online tutorial on reader performance in prostate MRI interpretation using PI-RADS.
• To assess improvements in diagnostic accuracy, sensitivity, specificity, and reader confidence.

Main Methods:

• An educational website with scrollable, annotated multiparametric prostate MRI cases (PI-RADS v2) was developed.
• Three radiology residents reviewed 60 prostate MRI examinations before and after completing the online tutorial.
• Reader performance was statistically analyzed using logistic regression and Wilcoxon signed rank tests.

Main Results:

• Online tutorial completion took under four hours for all readers.
• Sensitivity (57.8% to 73.3%) and negative predictive value (69.2% to 78.2%) significantly improved (P = 0.003 and P = 0.049, respectively).
• Reader confidence increased significantly (5.6 to 6.3 on a 1-10 scale, P = 0.026), while specificity, PPV, and PI-RADS score accuracy did not show significant improvement.

Conclusions:

• The online interactive tutorial effectively enhanced novice readers' sensitivity and negative predictive value for prostate tumor detection.
• This flexible online resource complements traditional teaching methods, potentially benefiting a larger number of learners.
• Targeted educational initiatives are still needed for optimal application of PI-RADS in prostate MRI interpretation.
