description Objectives: The aim of the present study was to compare the features of the structural complexity of the cerebral hemispheres in men and women using fractal analysis of outlined and skeletonized images, as well as quantitative analysis of digital skeletons of the cerebral hemispheres. Material and Methods: Magnetic resonance imaging brain scans of 100 individuals aged 18-86 years (44 males and 56 females) were investigated. Five tomographic sections of each brain were selected for morphometric study (4 coronal and 1 axial sections). The sections were preprocessed, and outlined and skeletonized images were obtained. Fractal analysis was conducted using the two-dimensional box counting method, and fractal dimensions of outlined and skeletonized images were determined. Additionally, quantitative analysis of skeletonized images was performed, determining the following parameters: branches, junctions, end-point voxels, junction voxels, slab voxels, triple points, quadruple points, average branch length, and maximum branch length. Results: We observed that both variants of fractal dimension in males and females did not show significant differences, although most quantitative parameters in males were larger than those in females. Conclusions: The spatial and structural complexity of the cerebral hemispheres, as characterized by fractal dimensions, is almost indistinguishable between males and females. However, in some individual tomographic sections, the male brain may exhibit a slightly higher number of end-point voxels, corresponding to the gyri of the cerebral hemispheres. The obtained data can be used in clinical practice for diagnostic purposes (e.g., for detecting malformations) and for theoretical studies in neuroanatomy.

Objetivos: El objetivo del presente estudio fue comparar las características de la complejidad estructural de los hemisferios cerebrales en hombres y mujeres mediante el análisis fractal de imágenes delineadas y esqueletizadas, así como el análisis cuantitativo de esqueletos digitales de los hemisferios cerebrales. Material y Métodos: Se investigaron resonancias magnéticas cerebrales de 100 individuos de 18 a 86 años (44 hombres y 56 mujeres). Se seleccionaron cinco secciones tomográficas de cada cerebro para el estudio morfométrico (4 secciones coronales y 1 axial). Las secciones fueron preprocesadas y se obtuvieron imágenes delineadas y esqueletizadas. Se realizó un análisis fractal utilizando el método de conteo de cajas bidimensional, y se determinaron las dimensiones fractales de las imágenes delineadas y esqueletizadas. Además, se llevó a cabo un análisis cuantitativo de las imágenes esqueletizadas, determinando los siguientes parámetros: ramas, intersecciones, voxels de punto final, voxels de intersección, voxels de losas, puntos triples, puntos cuádruples, longitud promedio de la rama y longitud máxima de la rama. Resultados: Observamos que ambas variantes de dimensión fractal en hombres y mujeres no mostraron diferencias significativas, aunque la mayoría de los parámetros cuantitativos en hombres fueron mayores que en mujeres. Conclusiones: La complejidad espacial y estructural de los hemisferios cerebrales, caracterizada por dimensiones fractales, es casi indistinguible entre hombres y mujeres. Sin embargo, en algunas secciones tomográficas individuales, el cerebro masculino puede mostrar un número ligeramente mayor de voxels de punto final, correspondientes a los giros de los hemisferios cerebrales. Los datos obtenidos se pueden utilizar en la práctica clínica con fines diagnósticos (por ejemplo, para detectar malformaciones) y para estudios teóricos en neuroanatomía.
