Rapid sequential scintiphotography in the radionuclide detection of subdural hematomas.

Abstract

Because of its simplicity and lack of morbidity, radionuclide brain scanning has proven to be of particular value in screening patients with suspected subdural hematomas. Approximately 80% of all subdural hematomas will be detected by static scintiphotos, with false-positive results proving to be as great a problem as false-negatives (1,2). Rapid sequential scintiphotography, a technique permitting the dynamic study of cerebral circulation, has received little emphasis as an adjunct to im proving scan accuracy in subdural hematomas. This paper reviews our experience and emphasizes the value of the circulation study.
