Point plots for average (A) Apparent diffusion coefficient (ADC) evaluated by mono-exponential (ME) method and IVIM parameters (B) Diffusion coefficient (D), (C) perfusion coefficient (D*) and (D) perfusion fraction (f) in patient cohort evaluated by five IVIM analysis methods (1) Bi-exponential (BE) method with three-parameter fitting (BE), (2) segmented BE with two-parameter fitting (BESeg-2), (3) Segmented BE with one-parameter fitting (BESeg-1), (4) BE with adaptive Total-Variation penalty (BE + TV) and (5) BE with adaptive Huber penalty (BE + HPF) at three time-points (t0, t1 and t2) in tumor and healthy tissue volume.
