Magnetic resonance imaging (MRI) is a new noninvasive imaging technique which can directly reveal cerebral infarcts (2–4, 6). One advantage of MRI over CT is that encephalomalacious foci can be visualized 3–6 h after vessel occlusion whereas CT needs approximately 24 h. Cerebral infarcts cannot be visualized in native CT scans during the “fogging effect” (isodensity of the infarct and missing signs of expansion) in the second or third week after the insult (1). However, MRI clearly identifies the infarct.
