[Endoscopic visualization of luminal organ and great vessels with three dimensional CT scanner. A new trial using...

Thirty cases examined by three dimensions CT scanner (3DCT) were reported. The observation of inner view using 3DCT were performed in 12 large vessels with vascular disorder, 10 pulmonary bronchus with lung cancer and 8 common bile ducts involved obstructive disease. In order to visualize interface of the lumen, a new software which was devekioed by HITACHI MEDICO Inc. and us was brought in. In all cases but one the inner view of the luminal organ was clearly demonstrated as 3D images and it was possible to judge some changes of luminal interface involved by the diseases. The 3DCT endoscopic image might be useful as a new endoscopic technique without fiberscopy.
