3T Magnetic Resonance Morphometric Study of the Neurohypophysis in Bulgarian Population

Investigation which devoted to the study of the age characteristics of the human body are becoming increasingly important. Magnetic resonance tomography is the most informative diagnostic method for intravital visualization of tissues and structures of the brain. It also allows you to more accurately see the picture of morphological features with age-associated changes. The aim of the study was to carry out a comparative analysis of the age-related morphometric characteristics of the cerebellum in male with mesocranic type of cranium in young and old age according to the data of magnetic resonance tomography. The analysis of the results of a morphometric study of the cerebellum on tomograms of 91 men examined for medical reasons was carried out. Depending on the age, the subjects were divided into two groups. Group I included 52 young men (22–27 years old, inclusive), group II included 39 elderly men (from 78 to 83 years old, inclusive). The transverse, longitudinal and vertical dimensions of the cerebellum were determined. When comparing the parameters of the linear dimensions of the cerebellum in the studied age groups of men, a statistically significant decrease in all indicators in old age compared with young age was revealed (p=0.042). There was no statistically significant difference between the parameters of the longitudinal and vertical sizes of the cerebellar hemispheres in individuals of each age group (p>0.05); there is a tendency for these sizes to prevail in the right cerebellar hemisphere. The results obtained can serve as the equivalent of the age-related anatomical norm of the cerebellum in young and old men, which will make it possible to use these data in basic and clinical research, as well as in medical practice.

Background/Aim. Changes in the morphology and the size of the corpus callosum, are related to various pathological conditions. An analysis of these changes requires data about sexual dimorphism of the corpus callosum, which we tried to obtain in our study. We also investigated the method of digital morphometry and compared the obtained results with the results of other authors obtained by magnetic resonance imaging or by planimetry. Methods. A morphological research included 34 human brains (cadavers of both sexes ? 19 female and 15 male aged 26?72 years). By digital morphometry using an AutoCAD software we performed measurements in the corpus callosum: the length (L), width in the half of its length (WW?), length of its cortical margin (LCM), area and perimeter of the anterior and posterior callosal segments, as well as the area and perimeter of the corpus callosum section area. The investigated parameters were analyzed and compared between the females and males. Results. There was not a statistically significant difference between the males and females in the investigated parameters of the corpus callosum (t test; p > 0.05), including the mean values of the two most important parameters, the surface of its midsagittal section area (males 654.11 mm2; females 677.40 mm2) and of its perimeter (males 19.61 cm; females 19.72 cm). The results obtained by digital morphometry were in the range of the results of other authors obtained by magnetic resonance and by planimetry. However, the value of Pearson coefficient of linear correlation between the section surface area and perimeter of the corpus callosum in the males was highly significant (rxy = 0.6943, p < 0.01), while in the females this value was statistically insignificant. Conclusion. Digital morphometry is accurate method in encephalometric investigations. Our results suggest that the problem of sexual dimorphism of the corpus callosum is very complex, because the identical variables (section surface area or its perimeter) do not exhibit the same behavior in males and in females, implicating that these variables even cannot be simply compared between the sexes.
