Semiologic considerations and clinical significance of magnetic resonance in 11...
Mauricio, J C; Fernandes, A; Cannas, J; Goulão, A; Medina, EThe author's experience with high-field Magnetic Resonance (Signa, 1.5 T, G.E.) in 11 cases of intracranial aneurysms (6 presenting as space lesion and 5 with symptoms of rupture) is reported. Spin-echo, gradient-echo and GRASS (fast-scan or flip-angle) sequences have been used and results compared with those of CT-scan and angiography.
