High resolution MRI at 7T suggests that T2* contrast may be sensitive to white matter composition and microstructure. In this study, the quantitative correlation between T2* relaxation rate (R2*=1/ T2*) and diffusion fractional anisotropy (FA) in white matter was investigated in a dozen of normal volunteers at 3T and 7T.
