Erectile dysfunction (ED) is a common and debilitating condition with physical, psychological, and pharmacological aetiologies. The physical causes can be divided into problems with arterial inflow, structural penile abnormalities, or problems with the venous occlusion mechanism. Penile Doppler sonography is a specialized technique requiring a thorough knowledge of the topic in order to aid diagnosis and direct subsequent treatment. This technique is indicated in those patients with erectile dysfunction who do not respond to oral pharmacological agents (e.g., PDE-5 inhibitors). This pictorial essay will visit the anatomy and physiology of penile erection, the technique for performing the procedure, and review the imaging features for specific causes of ED.
勃起功能障碍（ED）是一种常见且使人衰弱的病症，其病因涉及生理、心理和药理学方面。生理原因可分为动脉流入问题、阴茎结构异常或静脉闭塞机制问题。阴茎多普勒超声检查是一项专门技术，需要对该主题有全面的了解，以便辅助诊断并指导后续治疗。这项技术适用于那些对口服药物制剂（如磷酸二酯酶5抑制剂）无反应的勃起功能障碍患者。本文将介绍阴茎勃起的解剖学和生理学、该检查的操作技术，并回顾勃起功能障碍特定病因的影像学特征。
