Abstract

Reviewing of each parameters of MRI and PET scan in thirteen acute ischemic stroke patients according to their ROIs based on the lesion in MRI, lesion-cores and lesion-peris in MRI are relatively well correlated with infarction and ischemia of the PET criteria respectively. Among the parameters of PET scan, CMRO2 values seem to be bst correlated with T1 and T2 changes of the lesions in MRI of acute ischemic stroke. As those parameters of both imaging techniques are more related with the pathologic site than the type of the stroke, the changes of the parameters in stroke are greater when the lesion is located in cerebral cortex than in white matter. It is assumed that T2 change occurs in the early stage of the ischemic insult followed by more prominet T1 change with increase of water content which leads to the infarction of the tissue, but further confirmation is needed.
