Overview

This paired cohort blinded trial aims to assess the detection rate of clinically significant cancer of MRI-targeted biopsy compared to standard 12-core TRUS biopsy in men referred with clinical suspicion of prostate cancer who have had no prior prostate biopsy. The investigators hypothesize that additional MRI-targeted biopsy will detect more clinically significant cancers than standard TRUS biopsy. Main objective: To compare MR-target vs. standard 12-cores TRUS-biopsy for the diagnosis of clinically significant prostate cancer.

Before prostate biopsy, all patients be preceded by mpMRI. The mpMRI is read by an experienced radiologist according to the PI-RADS version 2 scoring system. PI-RADS scoring system is used to assign a degree of doubt prostate cancer. Depending on the PI-RADS score, MR targeted biopsy is determined. 1. MR-targeted biopsy using Artemis device fusion of MRI and ultrasound images would be performed. MR targeted biopsy would be performed by radiologist. 2. Next conventional ultrasound-guided 12-core systematic biopsy would be performed by urologist. This portion will be performed without information of the MRI report.
