Results of the initially analyzed subjects from the study of Li et al. [80]. b-values distribution: 0, 2, 5, 10, 15, 20, 25, 30, 40, 60, 80, 100, 150, 200, 400, 600 s/mm², and threshold b-value is 60 s/mm², 3T scanner. (A) Four healthy volunteers and three liver fibrosis patients cannot be separated by D_slow when b = 0 image is included for bi-exponential IVIM analysis; while the volunteers and three liver fibrosis patients can be separated by D_slow when b = 0 image is not included for bi-exponential decay IVIM analysis. (B) The same study subjects as in (A), healthy volunteers and liver fibrosis patients cannot be separated by PF when b = 0 image was included for analysis; while volunteers and three liver fibrosis patients can be separated by PF when b = 0 image was not included for analysis. (C): Seven healthy volunteers (green dots) and six liver fibrosis patients (red dots) can be separated by 3-dimensional display of three IVIM parameters (PF, D_fast, D_slow).
