Volumetric Descriptors of the Encephalic Ventricular System in Multislice Computed Tomography Images
Abstract
Introduction: Brain morphology and its association with development, functioning, and age-related neurodegenerative processes is crucial for the advancement of neurosciences, as well as for the diagnosis and monitoring of various nosological entities.
Objective: To determine volumetric variations of the encephalic ventricular system according to sex, in a population with normal global cognitive functions.
Methods: An observational cross-sectional study was conducted from July to December 2021 at the Conrado Benítez Oncological Hospital in Santiago de Cuba, using multislice computed tomography images. A non-probabilistic sample of 30 adults aged between 45 and 54 years was used. All subjects had negative neurological physical examination, psychiatric evaluation, and neuropsychological status, and had a prior indication for a simple cranial computed tomography, the results of which were entirely reported as negative for old or recent structural alterations.
Results: When evaluating potential factors related to volumetry, only the distribution according to sex and the volumetric values of the third ventricle of the brain showed statistical significance (p = 0.013). The volumes of the fourth ventricle and the lateral ventricles did not show statistical significance (p = 0.35).
Conclusions: Sex had a significant effect when correlated with the volumetry of the third ventricle, with greater magnitudes of this cavity observed in males. The cavities of the fourth ventricle and the lateral ventricles showed similar behavior, although without statistical significance.
