The Appearance of Peripheral Postsurgical Activity on Cerebral Dynamic Studies

Duke University Medical Center and Veterans Administration Hospital, Durham, North Carolina

ABSTRACT

Peripheral tracer activity seen on cerebral dynamic studies obtained following brain surgery has been evaluated. Abnormal peripheral activity was seen in the surgical site in the venous phase of studies performed within 6 months of surgery. Persistence of abnormal activity beyond 6 months on repeated examinations was not observed in this series. Identification of abnormal peripheral activity more than 6 months postoperatively suggests skull or scalp infection or peripheral intracranial abnormality.
