To become familiar with MR procedures in the examination of prostate with endorectal coil, using the most comprehensive study protocol. How to perform prostate 3D multi-voxel proton spectroscopy. To become skilled with correct sequence positioning. To correctly interpretate images, post-processing, spectroscopy and integration with clinical data.

We describe how to perform a full-comprehensive protocol for the prostate MR examination with endorectal and phased-array body coils. Our complete examination protocol includes multiplanar high-resolution T2-weighted sequence (with and without fat suppression), high spatial and time resolution 3D T1-weighted gradient-echo dynamic sequences with intravenous administration of contrast agent (gadolinium-chelates), multi-voxel 3D CSI proton spectroscopy with water- and fat-suppression pulses. The whole acquisition time is about 30 minutes. Postprocessing consists in: subtraction images, generation of dynamic intensity/time curves (placing multiple ROIs on the maximum enhancement foci), volumetric prostate sizing (using manual contouring), proton spectroscopy post-processing, and generation of colorimetric choline-citrate maps. We show pitfalls in post-processing, image and spectroscopy interpretation leading to correct diagnosis and integration with clinical data.
