Measurements suitable for intra-voxel incoherent motion
(IVIM) modelling of diffusion weighted (DW) MRI take
long (>10 minutes) as multiple averages and diffusion
weightings are measured. To determine the minimal
measurement time, we investigated how IVIM in the liver
and pancreas performs as function of measurement time.
We measured DW-MRI (9 averages, 14 b-values) in 16
healthy volunteers twice in two sessions. During post
processing we deleted measurements to assess the
performance as function of averages and b-values. We
find that IVIM can be done roboustly in 5 minutes using
5 averages and 12 b-values.
