Color Doppler ultrasound seems to be an accurate method to evaluate vascular erectile function, in particular the arterial supply of the penis. Because of its relative noninvasiveness and easy performance, it has to precede more invasive evaluation (cavernosography and invasive angiography). Combination of wave form pattern analysis with peak systolic velocity measurements allows differentiation between arterial and venous insufficiency. Fifty-one patients suffering from erectile dysfunction, were examined with use of color Doppler ultrasound. Nine had adequate vascular function with good penile tumescence. However, during these adequate (late) stages of tumescence, peak systolic velocity fluctuated significantly. We conclude that in the late stages of tumescence, velocity measurements are not reliable as a parameter of arterial function.
彩色多普勒超声似乎是评估血管性勃起功能，尤其是阴茎动脉供血的一种准确方法。由于其相对无创且操作简便，它必须先于更具侵入性的评估（海绵体造影和侵入性血管造影）。波形模式分析与收缩期峰值速度测量相结合可区分动脉性和静脉性勃起功能不全。对51例勃起功能障碍患者进行了彩色多普勒超声检查。9例患者血管功能正常，阴茎勃起良好。然而，在这些充分（后期）勃起阶段，收缩期峰值速度波动显著。我们得出结论，在勃起后期，速度测量作为动脉功能参数并不可靠。
