CT demonstration of prostatic zonal anatomy during dynamic contrast infusion.
CT of the pelvis was made after i.v. administration of 100 ml Omnipaque (300 mg I/ml) in 8 patients. The 1st series postcontrast was obtained dynamically and the 2nd 5 to 15 min after injection. Postcontrast enhancement of the prostate was shown in all patients. Dynamic contrast-enhanced CT was better than delayed postcontrast CT in showing the zonal anatomy in 6 patients. The method might be useful in patients where transrectal ultrasound is not applicable and when MR is not available.
