title: Radioactive oxygen 15O studies in cerebral neoplasms.
abstract: Methods of diagnosis and anatomical localization of cerebral neoplasms have reached a high level of efficiency. A new method of studying cerebral circulation and metabolism by a simple noninvasive technique of steady-state imaging during the inhalation of radioactive oxygen and radioactive oxygen-labelled CO2 is described. The results of preliminary studies of a group of cerebral neoplasms of various histological types are presented and the implications discussed.
