Outline of Final Research Achievements

We examined for the relationship between the advanced diffusion MR image acquired in term equivalent age of preterm infants and their short-term developmental outcomes in the first year of life. The parameters compared sensitively reflected cerebral development, but were not predictive of developmental outcome. In the future, it is necessary to examine the relationship between the developmental outcome and the rate of change of the parameters from neonatal to infantile term.
In addition, we evaluated the brain lesion of tuberous sclerosis using this imaging method and were able to delineate lesions more sensitively than with conventional MR imaging methods. These results were presented at a conference and can serve as a basis for studying the application of this imaging method in other neurological diseases.
