对141例脑或小脑梗塞患者在发病后尽快行CT检查。7天内重复检查，并进行放射性核素脑扫描。两种技术对缺血性梗死的总体检出率大致相等，范围从放射性核素扫描的58%到延迟CT的66%。发作当天通过CT检查的幕上梗死几乎有一半得到证实。早在第1天，晚至第25天观察到占位效应。
One hundred forty-one patients with cerebral or cerebellar infarction were examined by computed tomography (CT) as soon after the ictus as possible. The examination was repeated in 7 days, and a radionuclide brain scan was performed. The overall detection rate for ischemic infarction was approximately equal for both techniques, ranging from 58% for radionuclide scanning to 66% for the delayed CT. Almost half of the supratentorial infarcts examined by CT on the day of the ictus were demonstrated. Mass effect was observed as early as the first day and as late as the 25th day.
