The editors of this volume, recognizing the rapid expansion in the use of radioactive isotopes, offer this book as a convenient and basic reference to which those interested in the nervous system can add newer information. The value of these radioactive nuclides depends on the minute amounts used (so they do not load the system studied) and the use of external means of evaluating their distribution. Thus, radioactive sodium and other ions are used to study the blood-brain barrier and cerebral edema; xenon and other materials enable the investigator to study blood flow by inhalation or by intra-arterial or intravenous injections.

The diagnosis of brain lesions by intravenously injected positron and gamma-emitting isotopes have made "brain scanning" a common screening technique for the presence of intracranial lesions; more recently, the isotopes have been used to scan the spinal subarachnoid space. Injections into the spinal fluid permit introduction of materials carried . . . [Full Text PDF of this Article]
