Cerebral infarctions studied by [123I]iodoamphetamine. Clinical aspects of the findings on single photon emission computed tomography and transmission computed tomography.

We have used single photon emission computed tomography (SPECT) and the radioisotope [123I]-iodoamphetamine to study 16 patients with cortical and central cerebral infarctions. In 12 cases SPECT, in addition to changes at the site of infarction, showed areas of deficient uptake in other regions of the brain. Diaschisis as well as infarctions, not detected on the transmission computed tomography scanning, seem to explain these findings.
