Spiral CT virtual endoscopy of abdominal arteries: clinical applications.

Virtual endoscopy enables the creation of endoluminal views of the aorta and its branches by processing spiral computed tomographic (CT) images, thereby allowing the preoperative and postoperative evaluations of abdominal aortic aneurysms, aneurysms of the splenic, celiac, and common iliac arteries, and renal artery stenoses. Moreover, it is helpful for verifying the position of stents and endoprostheses from within the aortic lumen. This method is a promising addition to spiral CT.
