Imaging prostate cancer

Abstract

This article reviews the anatomy of the prostate gland, magnetic resonance (MR) imaging techniques, and the role MR imaging in the setting of prostate cancer. Sequences discussed include T2-weighted MR imaging, proton ((1)H) MR spectroscopic imaging, diffusion-weighted MR imaging, and dynamic contrast-enhanced MR imaging. MR imaging can be applied as an adjuvant tool to establish the diagnosis, localize, determine the extent, and estimate the aggressiveness of prostate cancers. The role of transrectal ultrasonography, computed tomography, and radionuclide scans is also briefly discussed.
