Twenty patients with stroke were studied for cerebral blood perfusion
abnormalities using N-isopropyl I-123 p-iodoamphetamine (IMP) and rotating
dual gamma camera emission computed tomography (ECT). After a single scan,
multiple transverse, coronal and sagittal section images were reconstructed
with a minicomputer. In eighteen patients, we determined the values of
regional cerebral blood flow (rCBF) in the region of interest using an
image. Transmission computed tomography (CT) studies were also performed on
the same day. ECT showed cerebral perfusion abnormalities in all cases,
while CT showed abnormalities in only 10 cases. This technique seems to be
useful for evaluating the rCBF in the deep brain.
