As a method of diagnosis in head injury, cerebral angiography, pneumoencephalography, and echo-encephalography have mainly been employed. These methods are convenient in acute type re-quiring emergency operation but are not sufficient for subacute or chronic type with complicated pathological state. In the present study, we have therefore applied methods using radioisotopes (con-ventional brain scintigraphy, cisternography and ventriculography) in addition to these conven-tional methods in 60 cases of brain contusion, skull fracture, intracranial hematoma, CSF rhinorrhea and posttraumatic disorder and obtained some interesting results. Rate of positive diagnosis of more 90% was obtained in intracranial hematoma and these tests were found to be effective in thin hematoma with difficulty in diagnosis even by angiography. As to the mechanism of radioisotope accumulation, discussions were made based on oper-ative finding and cases reported in the literature.

In cases with skull fracture, the results of the tests were correlated with clinical picture such as convulsion and hemiparesis. In operative finding, adhesion and cyst formation were noted in there.

In posttraumatic disorder, severity of the disease was classified into three grade according to the time of suffering from injury and clinical finding. RI tests finding specific to each grade were reported. Especially normal pressure hydrocephalus was classified into three types from the viewpoint of RI ventricular clearance and shunt operation was decided.
