Abstract: | The appearance of the cirrhotic liver on computed tomography can be difficult to evaluate and can frustrate the radiologist
distinguishing benign from malignant lesions. Hepatic edema, fibrosis, atrophy, and vascular abnormalities are common in the
cirrhotic liver and produce derangements in morphology, attenuation, and perfusion, limiting the accurate characterization
of hepatic masses. With the development of fast magnetic resonance (MR) sequences and dynamic postgadolinium-enhanced imaging,
most hepatic lesions with uncertain etiology on computed tomography can be accurately characterized on MR imaging. We describe
MR imaging techniques useful for imaging cirrhosis and its complications. We also illustrate the spectrum of findings in the
cirrhotic liver on dynamic gadolinium-enhanced MR imaging, including reticular and confluent fibrosis, fatty infiltration,
hemochromatosis, regenerating nodules, dysplastic nodules, hepatocellular carcinoma, and sequela of portal hypertension.
