NCT04571840

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.

Outcome Measures

Primary Outcomes (1)

  • Proportion of men with clinically significant cancer

    When biopsy results available, at an expected average of 30 days post-biopsy

Secondary Outcomes (7)

  • Proportion of men with clinically insignificant cancer (Gleason grade 3+3 / Gleason grade group 1)

    When biopsy results available, at an expected average of 30 days post-biopsy

  • Agreement between bpMRI and mpMRI for score of suspicion

    When MRI results available, at an expected average of 30 days post-MRI

  • Agreement between bpMRI and mpMRI for radiological staging decision

    When MRI results available, at an expected average of 30 days post-MRI

  • Agreement between bpMRI and mpMRI for treatment eligibility

    When treatment options discussed in multidisciplinary meeting, at an expected average of 30 days post intervention

  • Test performance characteristics for bpMRI & mpMRI when using the Likert scoring system in comparison to the PIRADS scoring system

    When biopsy results available, at an expected average of 30 days post-MRI

  • +2 more secondary outcomes

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.
