Role of Diffusion Weighted MRI in ASSESSMENT OF benign and malignant HEPATIC FOCal lesions in adult age group

Abstract

The liver is an organ in which various benign and malignant (primary or secondary) focal lesions can be detected.

Therapy requires an accurate diagnosis, which in turn relies mainly on appropriate imaging and image-guided biopsy.

Magnetic resonance imaging (MRI) is establishing a role as a primary diagnostic technique with evidence showing MR to have advantages over computed tomography (CT) regarding diagnostic sensitivity and specificity for many pathologies of solid organs, thus MRI is preferred when further characterization of these focal lesions is needed.

The clinical applications of DWI in the hepatic focal lesions include characterization & detection of these focal lesions as well as its use in evaluation of post therapeutic tumor response.
