METHODS： From February 2004 to May 2005, 100 patients （63 men, 37 women） underwent angiography performed with a 16-scanner multi-detector row CT unit （Toshiba, Aquilion 16）. All images were analyzed on a workstation （AZE Ltd, Virtual Place Advance 300）. The distance from the root of the IMA to the bifurcation of the LCA was measured by curved multi-planar reconstruction on a workstation. RESULTS： The IMA could be visualized in all the cases, but the LCA was missing in two patients. The mean distance from the root of the IMA to the root of the LCA was 42.0 mm （range, 23.2-75.0 mm）. There were no differences in gender, arterial branching types, body weight, height, and body mass index. CONCLUSION： Volume-rendered 3D-CT is helpful to assess the vascular branching anatomy for laparoscopic surgery.展开更多
