Value of MR diffusion imaging in hepatic fibrosis and its correlations with serum indices

Figure 1 Diffusion-weighted image. Diffusion weighted image: diffuse restricted tissue and long T2 tissue manifest hyper signal intensity (b = 700 s/mm²).

Figure 2 Diffusion coefficient. Apparent diffusion coefficient image: Tissues with higher diffuse degree manifest higher signal intensity, while diffuse restricted tissues manifest low signal intensity (b = 700 s/mm²).

Figure 3 Exponential apparent diffusion coefficient pseudo-color pictures. Exponential apparent diffusion coefficient image: Diffuse restricted tissues manifest higher signal intensity, free diffuse tissues manifest low signal intensity, and the effect of filtration efficiency of T2 is excluded (b = 700 s/mm²).
