Synopsis

We created an interactive application Learn Radiology with multi-parametric MRI - whole mount histology correlation for enhanced prostate MRI training of radiologists and validated whether the use of a newly created learning application can enhance prostate MRI training of radiologists using an observer study. Sensitivity (R1: 54%→64%, R2: 44%→59%, R3: 62%→72%), PPV (R1: 68%→76%, R2: 52%→79%, R3: 48%→65%) and confidence score (R1: 4.0±1.0→4.3±0.8, R2: 3.1±0.8→4.0±1.1, R3: 2.8±1.2→4.1±1.1, p<0.05) for prostate cancer diagnosis using mpMRI improved for all three radiologists along with inter-observer agreement (α 0.78→0.85) after being exposed to our developed teaching app.
