Central region morphometry in a child brain; age and gender differences.
BACKGROUND
Data on central region morphometry of a child brain is important not only in terms of providing us with information about central region anatomy of the brain but also in terms of the help of this information for the plans to be applied in neurosurgery.


OBJECTIVE
In the present study, central region morphometry of a child brain in mid-sagittal MR images was analyzed in age and gender groups.


METHODS
Different points determined previously, commissura posterior0 (PC) and the distances between cerebral cortex point (VCS) vertical to commissura anterior- commissura posterior line, sulcus centralis (CS), sulcus marginalis (MS), and the angle (α) between CS-PC-MS were determined and measured together with difference of gender in three different age groups (aged 6-9, 10-13, and 14-17).


RESULTS
Central region measures of the brains of boys aged 6-17 are higher than girls except for MS-PC distance. While VCS-PC, CS-PC, and MS-PC measures display a significant difference in the girls aged 14-17 when compared to the other age groups of 6-9 and 10-13 (P < 0.05), angle α is not significantly different in age and gender groups (P > 0.05). However, while VCS-PC, CS-PC and MS-PC distances show a significant increase in girls beginning from the age of 14, this increase is limited in boys.


CONCLUSIONS
Morphometric differences observed in different age groups in boys and girls shall contribute our evaluation of the alterations in brain development in both of genders and shall be useful in preparation of surgical operation plans to be applied to the central region.
