Computer assisted axial tomography in cerebrovascular lesions.
Computer assisted axial tomography was performed in 32 patients with clinically possible cerebrovascular lesions. Decreased absorption as a sign of infarction was found in 15, increased absorption as a sign of hemorrhage in 7 cases. In another 7 cases, diagnosed as hemorrhagic infarction, a simultaneous occurrence of increased and decreased absorption appeared. Increased absorption might also depend on compression effect of edema. In three cases no abnormal attenuation could be demonstrated. Infarctions could be observed years after the onset of the symptoms; intracerebral hemorrhages regressed slowly.
