Abstract

PURPOSE: To assess the ability of MR imaging with an endorectal surface coil for the depiction of normalantomical structure of prostate and its adjacent organs, MATERIALS AND METHODS: MR imaging using an endorectalsurface coil was performed in 23 male patients(age;20-75) to evaluate various prostatic and vasovesiculardisorders, i, e, 14 cases of ejaculatory problems, 3 cases of hypogonadism, and 4 cases of prostatic cancers and 2cases of benign prostatic hyperplasia, MR images were obtained with axial, sagittal and coronal fast spin echolong TR/TE images and axial spin echo short TR/TE images, Field of views was 10-12 cm and scan thickness was3-5mm. RESULTS: Depiction of normal anatomcial structures was excellent in all cases. On T2WI, zonal antomy of theprostate and prostatic urethra, urethral crest, and ejaculatory duct were cleary visualized. On T1WI,periprostatic fat plane is more cleary visualized. On transverse images, periprostatic structures were wellvisualized on T1WI, and on T2WI, anterior fibromuscular stroma, transition zone and peripheral zone could bereadily differntiated. Coronal images were more helpful in visualization of both central land perpheral zones. Vasdeferens, ejaculatory duct and vermontanum were also more easily defined on these images. Sagittal images washelpful in the depiction of anterior fibromuscular stroma, central zone and peripheral zone with prostatic urethraand ejaculatory duct in a single plane, CONCLUSION: High resolution MR imaging with and endorectal surface coilcan readily visualize the normal antomy of the prostate and its related structures and may be useful in theevaluation of vasious desease of prostate and vasovesicular system.
