Abstract
The frequency of abnormal brain scans in patients with cerebral vascular disease admitted to a stroke intensive care unit has been evaluated in relation to diagnosis, time after onset of symp-Loms, effect of delayed imaging and the degree of clinical neurological recovery. In patients with completed thromboembolic infarction, 33% had abnormal scans including 39% of those with hemispheric lesions and 14% wjth posterior fossa lesions. Completed hemorrhagic infarction occurred in seven patients, and three (43%) had abnormal brain scans. Of 14 patients with either transient ischemie attacks or reversible ischemie neurological deficit, two (14%) had abnormal scans. Twenty-seven percent of brain scans in patients with completed thromboembolic infarction were abnormal in the first two days after infarction, a higher frequency than previously reported. Delayed images confirmed the initial interpretation that the scan was either normal or abnormal in 71% of the cases while in 10% of the cases only the delayed views were abnormal. The frequency of abnormal scans was significantly greater in patients who died or had a large neurological deficit at discharge than in patients with lesser residual deficit.
