Fusion Target Biopsy of the Prostate Using Real-Time Ultrasound and MR Images. A Multicenter RCT on Target Biopsy Techniques in the Diagnosis of Prostate Cancer

Abstract

Background: The current standard technique for prostate cancer detection is trans-rectal ultrasound (TRUS) guided biopsy, and is renowned for its low sensitivity. Developments of multiparametric MRI techniques have increased the detection of significant prostate cancer. Currently there are three techniques utilizing MRI for targeted biopsy: MRI-TRUS fusion, 'cognitive' TRUS, and in-bore MRI guided biopsy. There is no consensus which should be preferred. The current study aims to compare prostate cancer detection rates of three target biopsy procedures.
