To augment information at digital subtraction angiography, 17 patients with 22 intracranial aneurysms underwent three-dimensional-display magnetic resonance (MR) angiography. Reconstructions created to simulate vascular endoscopy provided additional information in 18 aneurysms about the aneurysmal sac, its orifice and neck, and/or its relation to the parent vessel and nearby vasculature. No additional information was provided in two aneurysms, and two aneurysms were not depicted.
