Abstract:
The cross-sectional areas of the common iliac veins were measured by pelvic computed tomography (CT) in 51 patients. The left common iliac vein was significantly larger than the right (p less than 0.01) and in 35% of patients there was at least a two-fold difference between the cross-sectional areas of the veins. Recognition of this normal asymmetry is important when interpreting pelvic CT scans. It is thought to be due to the oblique course of the left common iliac vein and to partial obstruction of the left common iliac vein by the right common iliac artery.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
