The number of b-values needed for robust IVIM model
fitting, when imaging the liver, can usually not be
acquired during a single breath-hold. This introduces
the possibility of inter-scan motion, which most likely
will degrade the quality of the subsequent IVIM model
fit. In this study we show that non-rigid motion
correction is essential when image acquisition for IVIM
in the liver is split into multiple breath-holds.
