Abstract

To evaluate clinical visualization of intracranial aneurysms between 3D-TOF MRA with 3.0T MR and CTA with 16-slices MDCT. In a prospective series, 12 patients with 16 aneurysms were studies with 3D-TOF MRA and CTA. MRA were performed on a GE Signa 3.0 T system (Signa VH/i, GE) with 25/3/20 (TR/TE/FA). CTA were peformed on a 16 slice MDCT (Sensation 16, Somatom, Siemens) with IV shooting of 80 ml iodinated contrast mediumat antecubital vein at a rate of 3.5 ml/sec. Four among 12 patients underwent DSA for surgery. Size, shape, neck and parent vessel of aneurysms were evaluated for comparison of visualization and detectability of aneurysms.
