Purpose:
Development of an imaging method for detection of seminal vesicle invasion in patients with histologically proven carcinoma of the prostate.
Materials And Methods:
In 24 patients with histologically proven carcinoma of the prostate we preoperatively performed an antegrade vaso-vesiculography with non-ionic, iodine-containing contrast agent followed by a spiral CT of the seminal vesicles.
Results:
In 21 patients we achieved both a bilateral and a bulging enhancement of the seminal vesicle lumen. The method is introduced and described in detail.
Conclusions:
Intraductal application of contrast agent just before spiral CT results in unfold and bulging enhanced seminal vesicles. From the differentiation of the lumen, the wall, and the surrounding fat of the seminal vesicles as well as the enhanced ejaculatory ducts we expect information on tumorous infiltration in cases of histologically proven carcinomas of the prostate.
