Table 2 Results of Friedman’s test for comparison of IVIM parameters derived from all three fitting methods (M1, M2, M3) and for pairwise comparison of the fitting methods. A P value < 0.05 indicates significant difference in parameters obtained using the methods compared, which was highlighted by *
