[Comparative results of 99mTc scintigraphy and computerized tomography after contrast injection in cerebral pathology (author's transl)].
140 patients have been investigated by means of computerized tomography (CT) after contrast injection and radionuclide scan (RN scan). For patients with stroke (56 cases), RN uptake was more frequent (80%) at the 15th day of evolution, enhancement of hypodense images at CT reaches 100% at the 21st day. For the others pathologies (hematoma, tumors), the main difference between both examinations, was the volume of the lesions detected. RN uptake and CT enhancement both show the same blood brain barrier disturbance.

[Results of brain tomography in acute lymphoblastic leukemia in children].
Computerised axial tomography (CAT scan) was performed in 22 children with acute lymphoblastic leukaemia and in 13 the results were normal. In the other nine, various lesions were observed; namely intra-parenchymal lesions of density of (3 cases, one of which was calcified), intra-parenchymal lesions of decreased density (2 cases) and ventricular dilatation (7 cases). The role of the disease and of the treatment (intra-thecal methotrexate, cranial irradiation) in the development of these lesions is discussed. The CAT scan is an excellent method of monitoring the neurological problems in acute lymphoblastic leukaemia.
