Brief Summary
This prospective clinical trial (PRostate Imaging using Mri +/- contrast Enhancement (PRIME)) aims to assess whether biparametric MRI (bpMRI) is non-inferior to multiparametric mpMRI (mpMRI) in the detection of clinically significant prostate cancer. This means that we are comparing MRI scans that requires injection of IV contrast (the current standard practice) versus MRI scans that can be performed without IV contrast in the detection of prostate cancer.

- Masking Details
- Radiologist assessing MRI for suspicion of prostate cancer is blinded to the contrast sequence when reporting the biparametric MRI. After this report, they are unblinded to the contrast sequence and report the multiparametric MRI. All biopsies conducted as a result of MRI findings will be labelled as bpMRI and mpMRI, and diagnostic accuracy will be assessed against histology findings.
