Multiparametric magnetic resonance imaging of the prostate is an imaging modality that provides high-resolution images and is especially recommended for 3T MRI scanners. During the approximately 30-minute examination the prostate and pelvis are carefully assessed. The high-field strength scanner is using multiple resonant sequences utilizing the full capabilities of 3T MRI. The 3T scanner does not require the use of endorectal coil. The patient is only covered with a pelvic surface coil that maximizes the signal. Colon cleansing and emptying of the bladder is necessary prior to examination. The prostatic mpMR should be carried out after urological consultation, with the current results of the PSA (Prostate-specific antigen) and after possible biopsies.
The advantage of the prostatic mpMR carried out by a 3T scanner over the standard MRI examination involves combined analysis of the results of the anatomical study (T2-weighted sequence) with a study evaluating imaging-dependent diffusion (diffusion sequence – DWI-Diffusion Weighted Imaging) and dynamic contrast-enhanced evaluation (post contrast sequence-DCE-Dynamic Contrast-Enhanced Imaging). Due to this complexity the credibility of the mpMR is particularly high in the case of detecting the aggressive prostate cancer changes that are considered to be clinically relevant. The final results are described in a unified international protocol PIRADS v2. Included with the mpMR results are standardized prostate graphics with marked locations of pathological changes.
