MR imaging of inflammatory disease of the liver.

Although MR imaging has achieved a clear role in the assessment of focal benign and malignant hepatic lesions, its role in the evaluation of inflammatory processes in the liver is less well defined and studied. Many inflammatory diseases in the liver have no characteristic or specific imaging findings with MR imaging. Familiarization with these entities and their respective imaging findings is important, however, to aid in their identification and distinction from the more commonly studied neoplastic disease.
