Confident non-invasive diagnosis of pseudolesions of the liver using diffusion-weighted imaging at 3T MRI.

Purpose: Pseudolesions of the liver including focal steatosis or non-steatosis and THID (transient hepatic intensity differences) are often challenging, especially when imaging patients with underlying malignant disease. We evaluated the efficacy of diffusion-weighted imaging (DWI) in the diagnostic work-up of pseudolesions.

Materials And Methods: Forty-eight patients with pseudolesions of the liver were consecutively examined and the images were retrospectively analyzed.
