Role of MRI in characterization of benign hepatic focal lesions

ABSTRACT

Background: nowadays, magnetic resonance plays a key role in management of liver lesions, using a radiation-free technique and a safe contrast agent profile. The heightened soft-tissue resolution and sensitivity to intravenous contrast agents provided by magnetic resonance imaging [MRI] makes it an invaluable problem-solving tool for fully characterizing focal liver lesions [FLL]. Diffusion-weighted imaging [DWI] sequences have been shown to be an emerging contributor for liver MRI and are being incorporated in most abdominal MR protocols
