The clinical value of scintigraphic brain scanning. Experience at the Hillbrow Hospital, Johannesburg, South Africa

Patients were referred to the Department of Nuclear Medicine for brain scintigraphy to be screened for possible intracranial pathology. These referrals were made in order to reduce the heavy load on the transmission computerized tomography (TCT) facilities. Great clinical importance, therefore, has been attached to scintigraphic findings; this emphasizes the need for an accurate assessment of the predictive value of this procedure.
