AB  - Grey and white matter volumes of the cerebral hemisphere are essential for connectivityand cognitive function of the brain, they varies with sex, age, and health status of subjects.The aim of the present study is to measure the grey and white matter volumes andvolume fractions of the cerebral hemispheres to examine the sex differences in younghealthy Sudanese population. The study includes 139 healthy Sudanese subjects (80males and 59 females). Participant’s ages were ranging between 20-39 years old. Magnetic resonance imaging (MRI) was performed using a Philips 1.5 Tesla scanner. MRI ofthe subjects were analysed using the BrainSuite automatic segmentation software. Greyand white matter volumes and the volume fractions of cerebral hemispheres were estimatedusing the output data of the process. The mean volumes (cm3) of the grey matter ofright and left cerebral hemispheres of males (343.40 and 332.84) were larger than that ofthe females (301.21 and 316.81), respectively (p≤0.05). The mean volumes of the whitematter of right cerebral hemispheres of males were also larger than the females (192.54and 166.46), respectively (p≤0.05). The mean volumes of the white matter of left cerebralhemispheres of males and females (186.32 and 177.81) did not show statistically significantdifferences between the sexes, respectively (p≥0.05). The mean volume fraction (%)of the grey matter of right and left cerebral hemispheres of males (64.11 and 64.18) andfemales (64.45 and 64.12) did not show statistically significant differences between thesexes, respectively (p≥0.05). Our findings showed that the volume of the white and greymatters were larger in the males than that of the females. These findings are compatiblewith the fact that of the body and organ sizes are larger in the males. The most importantfindings are the volume fraction of the grey and white matters are same in both sexes.This means it is an independent value from the body size of the subject.
