Summary
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.
