Outline of Final Research Achievements

We performed analyses of microstructural abnormalities of the brain in children with various neurological diseases by using next generation diffusion MRI imaging technique. By applying a 32-axis gradient magnetic field and 3 b values using a 3 Tesla MRI apparatus, we determined the protocol to obtain appropriate diffusion kurtosis images. We attempted to detect microstructural abnormalities of the brain in children with various neurological diseases by means of fractional anisotropy (FA) and mean kurtosis (MK) values as parameters. In particular, many cases of perinatal brain damage could be examined. As a result, there was a resolution limit in diffusion kurtosis images, and it became clear that its detection capability was insufficient. Statistical analysis by tract-based spatial statistics revealed that there is a correlation between MK values and neurological outcome.
