MR Imaging of Meningiomas Including Studies With and Without Gadolinium-DTPA

摘要: Abstract: The magnetic resonance (MR) appearances in 12 successive cases of histologically verified meningioma are described. In six these intravenous gadolinium-diethylenetriamine pentaacetic acid (Gd-DPTA) (0.1 mmol/ kg) was administered. Each the eight tumours for which T1 measured displayed an increase above that white matter although T2 normal range brain two four cases. Inversion recovery most useful sequence demonstration tumour prior to administration Gd-DTPA and also highest level contrast enhancement after Gd-DTPA. overall findings compared well with enhanced X-ray CT.
