title: Measurement of regional cerebral blood volume by computerized axial tomography.
abstract: Computerized tomography has been used for the estimation of regional cerebral blood volume in a group of 18 patients. Sodium iothalamate was injected intravenously (1.75 ml/kg) to increase the absorption of x-rays in the cerebral circulation. A mean value of 5.7 ml/100 g was found for the cortex and 5.1 for tha thalamus.
