Abstract:

Objective By manual and automatic segmentation, the total volume, cerebrospinal fluid volume and white matter volume of normal human brain were obtained, and the differences between different genders and the patterns of changes with age were analyzed. At the same time, we give the software and parameters that can get better result. Methods The rough brain mask was obtained by software automatic segmentation and it would be refined manually. Then the brain masks would be divided into gray matter, white matter and cerebrospinal fluid by FSL-FAST, and finally statistical analysis was performed with SPSS 25.0 software.
Results The total brain volume of normal Chinese adults was about 1263.24 ml, and the total brain volume of males (1313.84 ml) was lager than the total volume of female brain (1173.11 ml). The difference was statistically significant. There were significant differences in total volume, gray matter, white matter and cerebrospinal fluid volume among different age groups. And there was no correlation between the age and the ratio of gray matter white matter. The total brain volume, gray matter, and white matter volume of males were larger than those of females, and as the age increases, the decline trend of these three sets of data is similar. The changes of total brain volume, gray matter volume and white matter volume with age were also similar in females. They reached their maximum at about 50 years of age, and then the volume gradually decreased. Conclusion The study on the changes of brain volume and the volume of gray matter, white matter and cerebrospinal fluid with age in different sexes can be used as a basis for identifying the changes of brain volume caused by diseases or the age.
