Transrectal Ultrasonography(TRUS) easily provides an accurate ass4essment of the seminal tract. In Magnetic Resonance Imaging(MRI) of the seminal tract, the anatomic relatinships are more clearly seen and the multiplanar imaging is available, so
a
more
difinitive diagnosis can be achieved, Although TRUS and MRI have been studied extensively, the findings of TRUS have not been compared with those of MRI. We studied 29 patients who were assessed with TRUS and MRI simultaneously due to disease of
the
seminal tract. The findings of cystic disease were coincident between TRUS and MRI. But the small size M?lerian duct cysts were not found in TRUS but were found in MRI. Hemorrhage of the ejaculatory duct and seminal vesicle, thickened ampulla
portion of
vas deferens were found only in MRI. Ejaculatory duct and seminal vesicle calcification were not easily found in TRUS due to their small size. The findings of seminal vesicle atrophy, dilatation and prostatic caloification between TRUS and MRI
were
discredpant. In conclusion, MRI is more helpful than TRUS in the diagnosis of small M?lerina duct cyst, small ejaculatory duct calculi, small seminal vesicle calculi, hemorrhage of ejaculatory duct and seminal vesicle and thickened ampulla
portion
of
vas deferens.
