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.
