Noninvasive evaluation of liver fibrosis: comparison of the stretched exponential diffusion-weighted model to other diffusion-weighted MRI models and transient elastography

ConclusionsDDC from the stretched exponential model is the most accurate DWI parameter with no confounding effect from steatosis and with overall similar diagnostic performance to TE.Key Points• The distributed diffusion coefficient (DDC) from the stretched exponential model is the most accurate DWI parameter for staging liver fibrosis.• DDC and transient elastography have similar good diagnostic performance for evaluating liver fibrosis.• The stretched exponential DWI model has no confounding effect by steatosis, unlike other DWI models.
