1.To review the basic branching patterns of the male pelvic vascular anatomy; 2.To review the origin and anatomical characteristics of the prostatic arteries (PA); 3.To compare the diagnostic performances of angio-MR, angio-CT and angiography; 4.To describe the main anatomical patterns and variations of the Internal Iliac Artery (IIA) and PA.

Major basic branching patterns of male IIA - Adachi/Yamaki’s classification Major IIA branches - Superior gluteal, Inferior gluteal, Internal pudendal arteries   Other dominant vessels - obturator and PA arteries  PA origin and anatomical findings Review of imaging findings - vascular male pelvis         16-slice angio-CT         1.5T Angio-MR         Angiography Sample cases and mimics  

1.The PA usually originates from the pudendal artery, with origins from the obturator or superior vesical arteries being less frequent; 2.The PA has some consistent anatomical findings with a characteristic 'corkscrew' pattern and terminating in the inferior vesical and intra-prostatic branches; 3.Angiography and 16-slice angio-CT show similar diagnostic performances in identifying the pelvic vascular branching patterns and the PA anatomy. Angio-MR failed to detect small vascular branches.
