Figure 1.
Region of interest (ROI) on the b = 0 diffusion weighted MR image (left) and the corresponding IVIM fitted curve of measured signal (right), showing a bi-exponential decay.
The ROI was placed over the whole liver avoiding artifacts and blood.
Figure 2.
D, f, and D* values in healthy livers and fibrotic livers.
D, f, and D* are significantly lower in fibrotic livers than in healthy livers.
