ABSTRACT

The use of radionuclides and the gamma camera for the visualization of cerebral blood flow is useful in the diagnosis and followup of patients with carotid-cavernous fistula. The procedure involves an intravenous injection of a small bolus of ^99mTc-pertechnetate followed by rapid-sequence images of the flow of the label through the cerebral vessels. This technique is simple, safe, and may be repeated at frequent intervals.
