A new method utilizing computer subtraction allows 2 separate radionuclide
angiograms to be performed during a single laboratory visit. Two separate
intravenous injections of the radionuclide are given so that the patient's
head can be imaged in 2 different projections. Background activity from the
first injection is subtracted by the computer to allow good resolution of
blood flow following the second injection. A static brain scan is performed
after the second injection. Although single-view radionuclide angiography
is widely used in the diagnostic evaluation of the brain, the addition of a
second projection provides additonal important diagnostic information. The
views obtained, however, must be determined individually for each patient
on the basis of the clinical history and neurologic signs. The selection of
appropriate views, the diagnostic quality of the studies, and the practical
clinical application of this technique are illustrated by 2 case reports.
