Answer

The National Comprehensive Cancer Network (NCCN) advises that although standard MRI techniques can be considered for initial evaluation of high-risk patients, multiparametric magnetic resonance imaging (mpMRI) can be used in the staging and characterization of prostate cancer. mpMRI images are defined as those acquired with at least one more sequence in addition to the anatomic T2-weighted images, such as diffusion-weighted imaging and dynamic contrast images. In addition, the NCCN guidelines recommend considering mpMRI in patients undergoing active surveillance if anterior and/or aggressive cancer is suspected when PSA increases and systematic prostate biopsies are negative. [6]

The 2016 EAU/ESTR/SIOG guidelines recommend mpMRI prior to performing a repeat biopsy when clinical suspicion of prostate cancer persists in spite of negative biopsies. During repeat biopsy, target any mpMRI lesions seen. Additionally, the guidelines recommend performing mpMRI for local staging and metastatic screening in predominantly Gleason pattern 4 intermediate risk patients and for local staging in high-risk localised prostate cancer.
