Abstract

Objectives: To explore the value of dual-energy computed tomography (DE-CT) angiography in diagnosis of arteriogenic erectile dysfunction (ED) patients and feasibility of new scanning area that excludes the testis.

Materials and methods: Ninety-three patients suspected of suffering arterial ED and 40 health volunteers underwent penile duplex Doppler ultrasound and DE-CT angiography (DE-CTA). The scanning range of DE-CTA covered whole arterial system of pelvis and testis was excluded. Two blinded investigators independently evaluated the arterial system that supplies the penis.

Results: Finally, 1596 segments were evaluated and 470 segments were judged to be abnormal. The distribution was: 2 (0.4%) in common iliac artery, 7 (1.5%) in internal iliac artery, 82 (17.5%) in internal pudendal artery, 89 (18.9%) in penile artery, 120 (25.5%) in dorsal artery, and 170 (36.2%) in cavernosal artery. The specificity, sensitivity, positive predictive value, and negative predictive value of DE-CTA in diagnostic were 86.02%, 87.50%, 94.12%, and 72.92%. Besides, the new scan area allowed for effective evaluation of the arteries while excluding the testis.

Conclusion: DE-CTA can provide unbiased, safe evaluation of the vascular status of the penile bed in patients with ED.

双能CT血管造影在动脉性勃起功能障碍诊断中的应用:扫描新技术，扫描新领域。

目的:探讨双能计算机断层扫描(DE-CT)血管造影在动脉源性勃起功能障碍(ED)患者诊断中的价值及排除睾丸的新扫描区域的可行性。材料与方法:93例疑似动脉性ED患者和40名健康志愿者行阴茎双多普勒超声和DE-CT血管造影(DE-CTA)检查。排除了DE-CTA对骨盆及睾丸全动脉系统的扫描范围。两名盲法调查人员独立评估了供应阴茎的动脉系统。结果:共评估1596个节段，判断异常节段470个。分布为:髂总动脉2例(0.4%)，髂内动脉7例(1.5%)，阴部内动脉82例(17.5%)，阴茎动脉89例(18.9%)，背侧动脉120例(25.5%)，海绵体动脉170例(36.2%)。DE-CTA在诊断中的特异性、敏感性、阳性预测值、阴性预测值分别为86.02%、87.50%、94.12%、72.92%。此外，新的扫描区域允许在排除睾丸的同时有效地评估动脉。结论:DE-CTA可对ED患者阴茎床血管状况提供公正、安全的评价。
