Abstract:
With recent technological advancements, multiparametric MRI (mpMRI) has evolved into an important tool in the detection, localization and staging of prostate cancer. Optimization of image quality is paramount to mpMRI technique. While PI-RADS version 2 established guidelines for minimum technical parameters, there is no uniformity in mpMRI protocols across institutions. This review will discuss the key sequences that comprise a mpMRI exam. Technical factors that affect image quality, such as pre-exam patient preparation, magnet field strength, endorectal coil utilization and sequence parameters will also be examined. Several emerging technologies with potential to aid in the maturation of mpMRI will be introduced.
