Шлуночкова система головного мозку в постнатальному онтогенезі в чоловіків

Abstract

У ході морфометричного дослідження магнітно-резонансних томограм проаналізовано співвідношення розмірів окремих структур шлуночкової системи в представників чоловічої статі різних вікових періодів. Вивчено гендерні особливості та міжпівкульну асиметрію відповідних показників. Introduction into medical practice of new methods of neuroimaging – computer and magnetic resonance tomography, changed principles of diagnosis of brain morphological changes and opened new horizons in the study of its structure. The aim of our study was to evaluate morphometric parameters of ventricular system of the brain on the results of MRI of men the period of mature and elderly. Object and methods. A survey was conducted in the department of radiation diagnosis of clinical institution «Rivne Regional Clinical Hospital» on computer tomograph General Electric Nealthcare «SignaMRI 1,5T» and in the office of magnetic resonance tomography ща clinical institution «Lutsk Clinical Hospital» on computer tomograph Signa Profile Ce Medical Sistem – 1,5 Tl in standard anatomical planes (sagittal, frontal and axial).bMeasurements were carried out in people without visual signs of organic lesions of the brain and skull. Brain imaging analyzes of men of different age groups, namely six tomograms (22–35 years) I mature period and 14 tomograms of elderly patients (61–74 years). 13 morphometric parameters of cerebrospinal fluid system of the brain were studied, namely the size of lateral, the III and IV brain ventricles and the length of aqueductus cerebri of men of different age groups. During the study morphometric magnetic resonance tomograms analyzed the size ratio individual structures ventricular system of men of various ages. Studied gender characteristics and interhemispheric asymmetry of relevant indicators. The study we found a significant increase in the size of the lateral ventricles in the age of men, namely length and width of the anterior horn of the lateral ventricle, both right and left; body width and length of the lateral ventricle posterior horn of the left side; the length of the lower horn; anteroposterior lateral ventricle size. Found that the height of III and IV ventricles of the brain, the length of water pipe tends to gradually decrease with age. It can be assumed that this age structural reorganization of the brain are caused by persistent metabolic changes that occur in the brain during the «aging». Conclusions. Thus, there is reason to believe that presented intravital morphometric characteristic of the man brain of different age persons and identified on this basis criteria of age brain reorganization may be of interest to experts in the field of age anatomy, neurophysiology and neurosurgery, and for specialists of MRI-diagnostic can be an anatomical standard of ventricular system of the brain.
