[Three-dimensional measurement of vascular lesions with virtual CT endoscopy "cruising eye view" method].

The purpose of this report is to propose a new technique which allows three-dimensional measurement of vascular lesions based on the virtual CT endoscopy "Cruising-Eye-View (CEV)" method. The view-point of CEV imagings was used as measuring point of vascular lesions. Using this technique, we could measure the actual length of arterial stenosis along the vessel in 3 patients with arteriosclerosis obliterans. The three-dimensional measuring technique with the CEV method may become a useful tool in treatment planning before interventional radiology, including metallic stent placement.
