summary

Objectives. The aim of the study was the assessment of vascularization of prostate in group of patients suffering from BPH and prostate cancer (CaP) and then the assessment of vasculo-stromal coefficient in peripheral and transitional zone of prostate.

Methods. The equipment used for the study was as follows: ultrasond equipment B&K 2002 Panther ADI with 3D reconstruction and the rectal linear double plane probe 7.5 MHz with power doppler option. The vasculo-stromal coefficient was defined as the ratio of blood vessels surface using power doppler and specially defined surface section of prostate using 3D reconstruction software options. 3D power doppler images were obtained before and after intravenous administration of Levovist. 39 patients with BPH and 14 with CaP were examined. The control group consisted of 10 young men.

Results. 1. The vasculo-slromal coefficient was highest in patients with BPH, average than in those with CaP, and lowest in control grup, 2. Administration of Lcvovist enhanced 5 times visualization of blood vessels in power doppler option. Visualization of blood vessels in power doppler option was enhanced 5 times after Lcvovist administration.
