Abstract

There is general agreement that in stroke victims, enhancement of the infarcted tissue on the computed tomography (CT) image occurs 2–4 weeks after the stroke episode1,8,11,13,15,16. On the other hand, a hypodense mass effect due to brain edema develops within a week of the episode7,10,11, 13,16. Therefore, the question arises whether in human cerebral infarction the blood-brain barrier (BBB) change is an earlier event than is usually accepted3. To obtain a high blood concentration of the contrast medium for a prolonged period of time, we employed long-term continuous infusion of contrast medium rather than the conventional bolus injection, to study CT enhancement during the acute phase of cerebral infarction.
