title: [MR imaging of basilar artery aneurysms].
abstract: Eight patients with basilar artery aneurysms (five fusiform, two saccular and one giant aneurysm) were studied by MRI at 1.5 tesla. Dilated lumen of basilar artery was detected in seven of eight patients on T2-weighted axial images. Deformity of pons was demonstrated in six of eight patients on T1-weighted midsagittal images. A fusiform aneurysm, 5 mm in diameter, could not be diagnosed by MRI. It was therefore concluded that MR imaging is relatively useful for diagnosing basilar artery aneurysms.
