Notes: This examination can only be ordered by urologists.  \nThe patient should ideally be 6 weeks post biopsy (if not consult radiologist) . The following information should be available to the radiologist at the time of MRI exam performance and interpretation:  \n1. Recent serum prostate-specific antigen (PSA) level and PSA history  \n2. Date and results of prostate biopsy, including number of cores, locations and Gleason scores of positive biopsies (with percentage of core involvement when available)  \n3. Other relevant clinical history, including digital rectal exam (DRE) findings, medications (particularly in the setting of hormones/hormone ablation), prior prostate infections, pelvic surgery, radiation therapy, and family history  \n1.5T should be considered when a patient has an implanted device that has been determined tobe MR conditional at 1.5T, but not at 3T.  \n1.5T is preferred when patients are safe to undergo MRI at 3T, but the location of an implanted device may result in artifact that could compromise image quality (e.g. , bilateral metallic hip prosthesis) .  \nPatient prep: Should be NPO for >4 hours prior to study if possible. Have patient void before examination. The patient should evacuate the rectum, if possible, just prior to the MRI exam. If an ERC is not used and the rectum contains air on the initial MR images, it may be beneficial to perform the mpMRI exam with the patient in the prone position or to decompress the rectum using suction through a small catheter.  \nOral contrast: None.  \nCoil: Body coil.  \nCoverage: Position the coil such that there is good coverage and signal from the prostate.  \nIntravenous contrast:  \nDose: 0. 1mmol/kg standard GBCA or equivalent high relativity GBCA  \nInjection rate: 2-3cc/sec starting with continuous image data acquisition (should be the same for  \nall exams)  \nAnti-peristaltic agent: None.  \nSequences:  \n1.
