Prostate Vascular Flow

“…Similarly, with prostatitis, markedly increased color flow reflects the severity of inflammatory cellular reaction [3]. To appropriately use transrectal sonography with Doppler techniques in the evaluation of these and other disorders of the prostate, it is essential that one understand the flow patterns of the normal prostate [12].…”

“…The prostate is supplied from the internal iliac arteries by the prostaticovesical arteries [12,16,17]. The prostaticovesical artery gives rise to two terminal branches, the prostate artery and the inferior vesical artery.…”

“…Tissue perfusion [21] is theoretically a more useful tool than the mean frequency map found in conventional color Doppler imaging in assessing inflammatory and malignant conditions of the prostate. Power Doppler sonography has been shown to be superior to conventional color Doppler sonography in revealing normal renal [22] and prostatic vasculature [12].…”

“…Each observer was asked to rank the images from most flow to least flow and to grade flow in each image according to a published scoring system [12]. Images from each volunteer were presented in random order to the observers.…”

Prostate vascular flow: The effect of the ejaculation on the power doppler ultrasonographic examination

“…For this reason, the Power Doppler sonography (PD) can accurately depict tissue perfusion, recognize slow flows, and is relatively angle independent (Zelli et al., ). In human medicine, this ultrasonographic technique resulted more accurate than conventional colour Doppler sonography in revealing normal prostatic vascularization (Keener et al., ). Tissue perfusion is theoretically a more useful tool than the mean frequency map found in conventional colour Doppler imaging in assessing inflammatory and malignant conditions of the prostate (Turgut et al., ; Chen, Fu, Chiang, Hong, & Yeh, ).…”
