Possibilities and prospects of the MR morphometry method in the diagnosis of dementia

Abstract

Dementia is one variant severe disorder’s higher cortical function and is currently considered as one most important cause a decrease in the quality household, social adaptation patients, and a violation their ability function in the world around them. It can be formed in a wide range disease, main which are neurodegenerative processes, in particular Alzheimer’s disease. In the diagnosis cognitive disorders, in addition to clinical and neuropsychological, as well as laboratory examination, modern methods computer neuroimaging plays an essential role. Same time, significant importance is attached research based on magnetic resonance, which has achieved great progress in recent years. Changes recorded by structural magnetic resonance imaging (MR tomography) often “lag behind” recorded clinical symptoms and are determined advanced disease. New MR methods have been proposed to verify early manifestations of neurodegenerative changes observed in the brain. These include, in particular, MR morphometry. It allows you to determine absolute values severity of atrophic changes, to establish their exact topical localization. Its use not only improves the possibilities of diagnosis pre-stage stages, but also improves quality of differential diagnosis various pathogenetic variants observed cognitive disorders. In addition, use special postprocessing data processing programs reduce the likelihood errors in interpretation received data. Currently, three options have been proposed for evaluating the results of MR morphometry, based on the analysis volume individual brain structures, thickness gray matter, as well as the spatial shape certain formations. Integrated use these options contributes highest quality MR morphometric examination of the brain during formation neurodegenerative process.
