Both IVIM and DTI are well recognized MRI methods for
quantifying flow and diffusion, respectively.
Simultaneously assessing both techniques (IVIM-DTI) has
recently been shown feasible in the kidney. We proposed
that the same technique is also feasible in the liver
with multiple breath holds and subsequent retrospective
motion compensation. Based on our result, IVIM-DTI
analysis is able to differentiate between hepatic blood
vessels and liver parenchyma, while minimizing the
pseudo-hepatic artifact.
