This report presents our experience with computed tomographic and radionuclide scans in 224 patients with ischemic or hemorrhagic infarcts or intracerebral hematomas secondary to cerebral occlusive vascular diseases. The results vary according to the site of vascular occlusion. The radionuclide angiograms and static scintigrams show four distinct patterns in cases of occlusion of the middle cerebral artery. Computed tomographic scans exhibit less variation in appearance and have a higher sensitivity in cases of recent ischemic infarction. The ''tentorial confluence sign'' is an important finding on static scintigrams in patients with occipital infarction; if this sign is not present, this diagnosis should be suspect. Earlier reports have established the value of computed tomography and radionuclide scans in the evaluation of cerebral infarction. In individual cases, however, each of these modalities may render nondiagnostic or false negative findings; combining both types of examinations and comparing results yield a greater likelihood of an accurate diagnosis of cerebrovascular disease. Computed tomography is clearly more valuable than radionuclide scans in the diagnosis and follow-up of hemorrhagic infarcts or parenchymal hematomas.
