Diffusion studies according to the origin of liver failure.

MR studies	Liver failure	MR parameters compared to control group
		ADC/MD	Diffusion tensor parameters
			FA	CL	CS
(Nath et al 2008)	Chronic	↑	↓	↓	↑
(Nath et al 2008)	Acute-on-chronic	≈	↓	↓	↑
(Ranjan et al 2005; Rai et al 2008; Saksena et al 2008)	Acute	↓	↓	↓	↑

MR parameters: ADC, apparent diffusion coefficient; MD, mean diffusivity; FA, fractional anisotropy; CL, lineal anisotropy; CS, spherical anisotropy.
