The purpose of this study was to assess the
variation of T2 values by T2 map with the pre-pulse of diffusion gradient
(=DW-T2 map). T2 value of GM was gradually decreased as b-value increased. From
this result, water diffusivity based selective removal of tissue component such
as perfusion fraction or extracellular extravascular space can be obtained
using DW-T2 map technique. This technique can reveal the more detain in the
human brain tissue characteristics.
