ON THE USE OF NEUROIMAGING STUDIES IN THE DIAGNOSIS OF ISCHEMIC STROKES

Abstract

Objective: To study the relationship of the clinical picture of ischemic stroke (II) and MRI in assessing changes in brain
matter and cerebral hemodynamics. Material and methods: The study was conducted at the Department of Neurology in
2017-2019. 110 patients with II confirmed by MRI and clinically examined. Results: The presence of an extensive heart attack
leads to complications and has an extremely poor prognosis. Significant criteria for the severity of the course of AI on MRI are
pronounced perifocal edema, the detection of leukoaraosis, severe internal and external hydrocephalus. The combination of
these signs gives reason to predict the worst outcome of ischemic stroke. So, with large infarct sizes with a morphologically
significant defect, but without the presence of these three factors, positive clinical and neurological dynamics are more
pronounced than in patients with smaller infarct sizes, but with the presence of these components. Conclusions: Changes in
the venous blood circulation of the brain are detected on magnetic resonance imaging and magnetic resonance angiography
and reveal a persistent reliable regular relationship with various brain conditions and carry important information about the
organization of its blood supply and identification of the degree and severity of vascular brain damage.
