Abstract

To investigate the feasibility and value of multi-slice spiral computed tomography angiography (CTA) in 3D imaging of internal pudendal arteries and their branches. Using 64-slice spiral computed tomography, we performed hypogastric CTA for 156 twenty to seventy years old males without vascular diseases. We assigned them to groups A (n = 83, 20 to 55 yr old) and B (n = 73, 56 to 70 yr old), and included 7 male patients with arterial erectile dysfunction (AED) aged 43 to 70 years in group C. We conducted maximum intensity projection (MIP), volume rendering (VR) and vascular analysis on the internal pudendal arteries and their branches, divided the MIP and VR images into 3 levels according to the resolution and continuity of the internal pudendal arteries and their branches for blind evaluation, and measured their diameters at various positions. VR images of the internal pudendal arteries and their branches revealed significant differences between groups A and B (P<0.05), but not MIP images (P>0.05). There were no dramatic differences between MIP and VR in displaying internal pudendal arteries and their branches (P>0.05), nor any remarkable differences in the diameters of bilateral internal pudendal arteries and their branches at...Continue Reading
