[Computer tomographic measuring procedure in generalized brain edema after craniocerebral trauma].

Computer tomography enables for the first time the direct demonstration of the consequences of a craniocerebral trauma. In the computer tomogram, the cerebral oedema is dominating as an area of reduced density (hypodense region). Three different measuring techniques are compared and their application in 43 craniocerebral traumata discussed. Among the measuring methods employed, the area index shows the greatest diagnostic reliability in the computer-tomographic findings of a posttraumatic cerebral oedema. The partial volume analysis without application of a contrast medium is of little use for computer-tomographic clearing of the question of a generalised cerebral oedema after SHT while the density index is only suitable in conjunction with additional parameters.
