The Inversion Recovery DTI technique was recently introduced to provide fibre-specific estimates of the relaxation time T1 and of the diffusion tensor in areas of crossing fibres, that characterise more than 90% of the human brain. Here, we demonstrate the feasibility of IR-DTI in vivo in the human brain, for the first time, and show that different fibre systems have distinct values of T1, reflecting their different myelination properties.
