The Role of Diffusion Weighted MR in the Characterization of Malignant Hepatic Focal Lesions

Abstract

Hepatic focal lesions may be benign or malignant. Diffusion weighted MRI in the liver is a relative new and increasingly used technique . It can be obtained during a single breath-hold, there is no need to use contrast media and it provides information that reflects tissue cellularity and organization. ADC maps can provide quantitative measurements of tissue water diffusivity. It proved to be helpful in the characterization of between malignant hepatic focal lesions.

Key Words: Diffusion weighted MRI, hepatic focal lesions, characterization, liver.
