title: Angiodynography (color-coded duplex sonography) in the evaluation of vasculogenic impotence.
abstract: The penile arteries of 18 men with erectile dysfunction were examined by angiodynography (color-coded duplex sonography). Blood flow velocity was measured before and after intracavernous injection of papaverine/phentolamine. The angiodynographic findings were compared to arteriography. Normal values of peak flow velocity (after injection) were obtained from 6 men with normal arteriographic findings (deep artery greater than 25 cm/s, superficial artery greater than 30 cm/s). Angiodynography enables good imaging of the four penile arteries superior to duplex sonography. A strong correlation with the arteriographic findings could be found. Thus noninvasive angiodynography may replace penile arteriography for the routine evaluation of impotence.
