High resolution magnetic resonance imaging of vascular lesions at the skull base: a review.
Conventional spin-echo magnetic resonance imaging is now being used routinely for the evaluation of brain parenchyma. It has also proven to be an excellent modality for the diagnostic assessment of the larger cerebral blood vessels, typically those found in or adjacent to the skull base. It possesses sufficiently good spatial and contrast resolution to be used for the diagnosis of arterial thrombosis, atherosclerotic and "berry" aneurysms, arterial dissection and venous sinus occlusion in preference to computed tomography. It has reduced, but not eliminated, the need for confirmatory angiography for these indications.
