Usefulness of endoscopic imaging of cerebral aneurysms is presented. 3D- luminal images were obtained using a new processing technique which extracts CT numbers in the boundary region between the vessel wall and contrast media filling in the vascular lumen. Clinical application of this technique to complicated large cerebral aneurysms showed that, with this 3D-CT endoscopic images and MRA, anatomical details of cerebral aneurysms such as the orifice of the aneurysm, intraluminal thrombus, and calcification of the wall could be clearly demonstrated. We operated on two large, complicated aneurysms after obtaining 3D-CT endoscopy images of the aneurysms. Such information was found to be very useful when operating on difficult and complicated cerebral aneurysms.
