ABSTRACT
A total of 15 adult male (2 cases of normal, 3 cases of benign prostatic hyperplasia, 3 cases of Prostatic cancer, 4 cases of obstructive azoospermia and 3 cases of hemospermia) were evaluated of their prostates and seminal tracts with magnetic resonance(MR) imaging using an endorecta1 surface coi1. On T1W1, the prostatic capsule, periprostatic venous plexus and neurovascular bundle were clearly defined. The zonal anatomy and internal structure of the prostate were clearly visualized on T2W1. The invasion of cancer into the prostatic capsule or the neurovascular bundle could be defined. More of these anatomical depiction, we found some other possible pathophysiologic process such as inhomogeneous signal intensity of seminal plasma in hemospermia and wolffian remnants in vasal agenesis Our results show the value of MR imaging with endorectal surface coil in the evaluation of morphology and pathologic process of the prostate and seminal tract.
