Optimising the number of cores for <scp>magnetic resonance imaging</scp> ‐guided targeted and systematic transperineal prostate biopsy

Abstract

sTB detected Gleason score 7-10 cancer in 25% more of the men than a two-core TB approach, and in almost as many men (91%) as the 20-26-core combined TB+SB, while needing only 10-20 cores. A four-core extended TB may suffice for large, highly suspicious anterior lesions in small or slightly enlarged prostates.
