Characterisation of compartmental diffusion and transverse relaxation properties of rat ischaemic tissue after stroke

Motivation: Conventional multi-echo NODDI, where the intrinsic diffusivity is fixed to a brain-wide value, has limited applicability in tissue pathologies where this parameter is significantly altered, e.g. ischaemic stroke. Goal(s): A recently proposed estimation method for multi-echo NODDI with released intrinsic diffusivity is applied here to investigate the diffusion and relaxation properties…
