Magnetic resonance-based total liver volume and magnetic resonance-diffusion weighted imaging for staging liver fibrosis in mini-pigs

Figure 1 Magnetic resonance images. A-C: In a mini-pig with liver fibrosis stage 2, diffusion weighted images of the liver are obtained with b values of 300, 500 and 800 s/mm², respectively; D-F: Corresponding apparent diffusion coefficient maps. Three regions of interest are carefully drawn on the right lobes of the liver for each b values; G: A manual tracing of the liver is shown on an axial contrast-enhanced magnetic resonance imaging, and the outline shows the liver areas (S).
