Digital subtraction angiography (DSA) was used in the investigation, by dynamic cavernosography, of 35 men with acquired erectile impotence. The benefits of using DSA included shorter examination times, lower contrast medium dosage and better definition of abnormal veins. In particular deep crural veins are more clearly seen than in conventional studies and these may be of more importance than was previously thought.
数字减影血管造影术（DSA）被用于对35名后天性勃起功能障碍男性进行动态海绵体造影检查。使用DSA的益处包括检查时间更短、造影剂用量更低以及异常静脉的清晰度更高。特别是与传统研究相比，深部脚静脉看得更清楚，而且这些静脉可能比之前认为的更为重要。
