Abstract

Objective To compare computed tomography (CT) angiography (CTA) obtained by multi-slice CT (a new minimally invasive method) with the current standard of arterial imaging, digital subtraction angiography (DSA), in diagnosingarteriogenic erectile dysfunction (ED). Patients and methods Twenty-one patients with suspected arteriogenic ED underwent DSA and CTA after providing informed consent. Prostaglandin El was injected into the penile cavernosal body and then non-ionic contrast mediumwas rapidly infused into the antecubital vein. The DSA and CTA images werediagnosed as showing a normal or abnormal status by three reviewers independently. CTA was undertaken on an outpatient basis but DSA required hospitalization. Results In the 42 internal pudendal arteries, DSA showed 28 normal and 14 impaired arteries: CTA showed 21 normal arteries and 21 occlusions. The CTAimage correlated closely with the diagnosis of stenosis or occlusion in internal pudendal arteries, with a sensitivity or 93%, a specificity of 71%, and an accuracy of 79%. In the cavernosal arteries, DSA depicted 14 normal and 28 impaired arteries: CTA showed seven normal arteries and 35 occlusions. The CTA image agreed closely with the diagnosis of stenosis or Occlusionin cavernosal arteries, with a sensitivity of 96%, a specificity of 43% and an accuracy of 79%,. Of the 42 inferior epigastric arteries, DSA could not depict 11 arteries but CTA showed all 42 inferior epigastric arteries. Conclusions CTA images correlated with DSA images; at present DSA is better than CTA in visualizing stenosis in fine arteries. However. CTA is less invasive and relatively inexpensive and in future will probably provide evengreater improvements in graphic quality. CTA would be an adequate replacement for DSA in evaluating internal pudendal arterial stenosis.
