OBJECTIVE

The establish the anatomical characteristics of the thalamuses according to magnetic resonance imaging data in men and women of mesocephalic individuals of the first and second periods of adulthood and to conduct a comparative analysis of them.

MATERIAL AND METHODS

The analysis of the results of morphometric thalamuses’ examination in 102 patients undergoing the brain examination in the Department of radiation diagnostics in the period 2019—2020 was carried out. Group I included 25 men and 25 women of the first adulthood period. Group II consisted of 27 men and 25 women of the second adulthood period. There were no diseases and injuries of the central and peripheral nervous system, alcohol and drug addiction in the anamnesis of the examined patients. They were all right-handed. The subjects agreed to a magnetic resonance imaging examination that was carried out strictly to indications. We determined the transverse, longitudinal and vertical thalamuses’ dimensions and conducted a comparative analysis of the indicators.

RESULTS

The transverse size of the thalamuses decreases by 7.8±0.67%, the longitudinal size decreases by 4.6±0.21%, the vertical size becomes smaller by 1.3±0.08% in both genders from the first period to the second period of adulthood. There was a tendency to the predominance of indicators of all three linear sizes of the thalamus in men in comparison with women without a statistically significant difference (p>0.05).

CONCLUSION

A comparative analysis of the linear thalamuses’ dimensions in the right and left hemispheres of the both genders subjects did not confirm the statistically significant difference between them and represented he tendency to the parameters prevalence in the left hemisphere (p>0.05).
