Cerebral toxoplasmosis in AIDS patients, CT and MRI images and differential dia...

Cranial computed-tomographies (CT) and magnetic resonance imaging (MRI) of 14 patients with AIDS and central nervous system toxoplasmosis (CNST) were reviewed. In spite of the low specificity of CT and MRI findings in CNS mass lesions of AIDS patients, there are some features which have been observed as more typical of CNST, namely: 94.9% of the lesions were round shaped and 94.5% had ring or nodular enhancemen...

Semiologic considerations and clinical significance of magnetic resonance in 11...

The 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. Magnetic Resonance findings, relating to blood flow and oxidation of haemog...
