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