The primary objective is to demonstrate non-inferiority of the detection rate of clinically significant prostate cancer (csPCa) in targeted biopsies based on PCaVision imaging (PCaVision pathway) in comparison with the detection rate of clinically significant cancer in targeted biopsies based on MRI (MRI pathway).
All patients will undergo imaging using MRI and PCaVision during which suspicious lesions will be identified based on each imaging technique independently with readers being blinded for the results of the other imaging technique. Thereafter, a MRI targeted 3-core biopsy per lesion (maximum of 2 lesions) and/ or a PCaVision targeted 3-core biopsy (maximum of 2 lesions) will be performed by a one physician if suspicious lesions have been identified based on imaging. If lesions have been identified with both PCaVision and MRI in the same patient, the order of the targeted biopsies will be randomized. If the same lesion has been identified on both MRI and PCaVision, both a MRI-targeted and a PCaVision targeted biopsy will be separately performed. Histological examination of the targeted biopsies will be performed to determine presence of clinically significant prostate cancer.

| MRI targeted biopsy pathway | Diagnostic Test | MRI sequences will include at least T1-weighted, T2-weighted, Diffusion-weighted imaging (DWI) and calculation of apparent diffusion coefficient (ADC) maps. Scoring of suspicion will be performed using the European Society of Urogenital Radiology (ESUR) PI-RADS standardized scoring system. All lesions will be marked and delineated for MRI-TRUS fusion 3D multiparametric ultrasound (mpUS). |
