Abstract:
Objective To study the normal changes in brain during childhood by analyzing the diffusion characters of different regions and different age phases with diffusion tensor imaging (DTI). Methods DTI was performed in 63 children (age range, 2 days to 9 years) without brain abnormalities and the data measured in ADC maps were analyzed statistically. Results (1) There were significant differences in ADC values among some different regions of brain tissue; (2) In babyhood, the ADC values in gray matters decreased faster than in white matters; (3) The ADC values decreased with the increasing of age , and show negatively exponentially correlation with age. Conclusion DTI shows the changes of brain tissue composition in vivo, with which normal changes in brain during childhood can be evaluated.
