Doppler evaluation in erectile dysfunction (ED) has a significant role in determining the cause of ED. The advantages of penile Doppler and pharmacologic duplex ultrasonography include objective, minimally invasive evaluation of penile hemodynamics at a relatively low cost. Arteriogenic ED may be secondary to peripheral vascular disease and diabetes, or may be seen in association with coronary artery disease. Various parameters, such as diameter of the cavernosal artery, peak systolic flow velocity, degree of arterial dilatation and acceleration time, have been suggested for the diagnosis of arteriogenic ED, but peak systolic flow velocity is the most accurate indicator of arterial disease. This second part of the review article describes the various causes of ED and the interpretation and evaluation of color flow Doppler examination in ED.
多普勒评估在勃起功能障碍（ED）中对于确定病因具有重要作用。阴茎多普勒和药物双功超声检查的优点包括以相对较低的成本对阴茎血流动力学进行客观、微创评估。动脉性ED可能继发于外周血管疾病和糖尿病，也可能与冠状动脉疾病相关。已经提出了各种参数，如海绵体动脉直径、收缩期峰值流速、动脉扩张程度和加速时间，用于诊断动脉性ED，但收缩期峰值流速是动脉疾病最准确的指标。这篇综述文章的第二部分描述了ED的各种病因以及ED中彩色血流多普勒检查的解读和评估。
