Gadolinium-enhanced MR imaging of cerebral venous angiomas with emphasis on their drainage.

摘要: Gadolinium-enhanced MR was performed in 28 patients with 17 supratentorial and 11 cerebellar venous angiomas. The use of gadolinium allowed detection 9 angiomas (32%) that were not visible before or which only recognized retrospect. Before the peripheral medullary veins are typical for these malformations visualized 4 (23%) 5 (45%) lesions, a total After intravenous administration seen 27 (96%) Extension lesions to wall ventricles 24 28, 16 8 cerebellar, after gadolinium. This information missed on plain 6 lesions. type drainage, either superficial deep, could be determined by gadolinium-enhanced all cases where angiography available comparison. this eight patients. adds significant study angioma.
