Intracranial Vascular abnormalities: value of conventional MR angiography

ABSTRACT

Forty-eight patients with a variety of intracranial vascular abnormalities were studied by conventional MR angiography. It proved to gave an important role in the diagnosis of 12 cases of vessel thrombosis, 15 aneurysms, 10 arteriovenous malformations, 3 cases of idiopathic sinus thrombosis, 7 cases of neoplasms adjacent to venous sinuses and a case of megadolichobasilar artery. The MR findings were correlated with clinical, CT and conventional angiography findings when available. This study highlights some of features of the intracranial circulation that make conventional MR angiography valuable in the demonstration of vascular disease
