Figure 13. a, b.

Preprocedural MRA with DSA correlation shows a type III uterine artery origin, in a 41-year-old woman. 3D reconstructed MRA image (a) clearly depicts the right uterine artery, inferior and superior gluteal arteries, originating at the same level from the internal iliac artery, as a trifurcation. DSA image (b) obtained with selective right internal iliac artery catheterization demonstrates good correlation with MRA findings. IG, inferior gluteal; II, internal iliac; SG, superior gluteal; UA, uterine artery.
