  • Abstract
  • Look Inside

In thirteen patients with the major cerebralarteial occlusion demonstrated by cerebral angio-graphy, angiographies were repeated to inspectrecanalization, and brain scans were performed at3-4 weeks and/or more than 5 weeks after thestroke. Five cases demonstrated recanalizationwithin seven days after the onset. All cases afterrecanalization showed increased uptake of Tc-99mwith brain scans perfomed at 3-4 weeks after thestroke.

In spite of diagnostic value in the acute stage,aingiographies sometimes do not provide diagnosticinformation in the chronic stage because of fre-quent arterial recanalization. On the other hand,brain scans frequently provide diagnostic infor-mation even in the chronic stage. Consideringthe mechanism of high uptake of radioisotope inbrain scans, it may be natural that findings ofbrain scans accurately reflect brain tissue damagecaused by ischemia with or without arterial re-canalization. Brain scans frequently enable "retro-spective" diagnosis of cerebral infarction even atthe chronic stage.
