To evaluate the value of penis perfusion CT for providing hemodynamic features information in patients with erectile dysfunction. 

17 patients (average 36.3 years) with clinically suspected vascular erectile dysfunction underwent penis perfusion imaging by using a 256-slice CT scanner. All images were transferred to a commercially available workstation (Extended Brilliance Workspace) for analysis. 3D CT angiographic images generated from perfusion source data were obtained in all patients. The hemodynamic changes of corpus cavernosum were analyzed on perfusion parameter maps.

Penile arterial vascular abnormalities including stenosis, interruption and occlusion were observed in 11 patients. Bilateral hypo-perfusion was observed in 1 case with bilateral vascular abnormality, 1 case with unilateral penile vascular abnormality, and 1 case without penile vascular abnormality. Ipsilateral hypo-perfusion was observed in 6 cases with unilateral penile vascular abnormalities, bilateral hyper-perfusion was observed with 1 case of unilateral penile vascular abnormality.

Hemodynamic features of corpus cavernosum can be assessed by CT perfusion method, and can provide additional diagnostic information to penile vascular changes for erectile dysfunction patients.

Perfusion CT is a noninvasive, quantitative assessment method, and providing the corpus cavernosum microcirculation hemodynamic information.
