Left: example of region of interest placement in the liver in coronal acquisition (b=800 s/mm2). The average signal intensity was used to extract IVIM diffusion parameters using biexponential fitting. Right: Evolution of the error for each IVIM parameters (D in blue, D* in green, and PF in black) of optimal b-values subsets (as given in Table 3) compared to 16 b-values reference parameters. The dashed lines indicate the 16 b-values test-retest error for each parameter (D* reproducibility lies outside the graph, as shown by the arrow). For any number of b-values down to 4, deviations of IVIM parameters from the 16 b-values distribution were within the test-retest error.
