[Virtual CT endoscopy "Cruising Eye View": development and clinical applications].

We have developed a virtual CT endoscopy, designated as "Cruising Eye View (CEV)", which have generated from spiral volumetric CT data and reconstracted using a new three-dimensional image reconstruction technique. Using this new method, we have reconstructed the inner image of patients with aortic dissection (2 cases) and arteriosclerosis obliterance (3 cases). The view point and view direction could be set arbitrarily in the vessel, so that the site, configuration, and/or degree of the intravascular abnormalities were recognized at first glance. Virtual CT endoscopy with CEV method is a promising, non-invasive strategy for archiving the inner image of diverse aorto-arterial pathologies.
