Abstract
Magnetic resonance (MR) angiographic studies of 14 patients with intra cranial aneurysms (AN) were analyzed retrospectively as compared with contrast angiographic studies. Eighteen of 19 (95%) lesions were detec ted, and the relation between AN and their parent vessels was precisel y assessed. The diameter of the smallest aneurysm detected in bur case was 3 mm. However, small vessels around AN were not visualized. There fore, MR angiography (MRA) is definitely not a substitute for preopera tive contrast angiography. MRA is a useful screening tool for nonruptu red AN, but further refinement is required to evaluate emergency ruptu red AN.
