Neurovisualization and electroencephalographic criteria for diagnosis of ischemic lesions of brain

Abstract

The results of computer-tomographic (CT), magnetic-resonance (MR) and electroencephalographic (EEG) studies are given, performed in 104 patients with cerebral ischemia, diagnosis of which caused significant difficulties. Verification of hemispheric ischemic insult with the help of CT and MR during the first three days is possible only in case of squeezing and displacement of the ventricular system and developing of acute hydrocephalus. The most reliable CT and MR data can be revealed on the 7—11-th day of sickness. Insults of the trunk are diagnosed (more reliably by MR) in one third of patients. Method of standard EEG retains its significance when diagnosing small brain infarcts of cortical or subcortical localization. The method of topographic mapping of EEG is more informative and allows to diagnose brain infarct, as well as to observe its dynamics in 4/5 of patients.
