The relationship between neuroimaging biomarkers of SPECT and neuropsychological testing data in chronic cerebral ischemia in patients exposed to man-made radiation in the long term

Diagnostics of chronic cerebral ischemia in Chernobyl Nuclear Power Plant liquidators in the late period, when neurodegenerative processes have already started and treatment in most cases is unable to stop or reverse them, but it is possible to slow down the progression of cognitive disorders and prevent the development of dementia, is of crucial importance. Therefore, one of the most promising methods of neuroimaging is single-photon emission computed tomography (SPECT). SPECT has certain advantages over other perfusion methods of neuroimaging, as it reflects regionalhemodynamics with the capture of the entire volume of the brain. It has sufficient sensitivity and specificity when examining patients with cognitive disorders.Purpose of the study. To study the relationship between changes in SPECT parameters and the results of neuropsychological testing in Chernobyl disaster liquidators.
