Temporal learning curve of a multidisciplinary team for magnetic resonance imaging/transrectal ultrasonography fusion prostate biopsy.

Abstract

Both transperineal and transrectal ultrasound (TRUS)-guided systematic biopsy are accepted methods to diagnose prostate cancer (PCa). However, systematic sampling misses up to 47% of tumors 0.5 mL or larger and under-represents the tumor grade in 38% of cases [1,2]. These shortcomings result in underestimated risk and repeat prostate biopsies.
