Abstract
The appearance of the cirrhotic liver on computed tomography can be difficu lt to evaluate and can frustrate the radiologist distinguishing benign from malignant lesions. Hepatic edema, fibrosis, atrophy, and vascular abnormal ities are common in the cirrhotic liver and produce derangements in morphol ogy, attenuation, and perfusion, limiting the accurate characterization of hepatic masses. With the development of fast magnetic resonance (MR) sequen ces and dynamic postgadolinium-enhanced imaging, most hepatic lesions with uncertain etiology on computed tomography can be accurately characterized o n MR imaging. We describe MR imaging techniques useful for imaging cirrhosi s and its complications. We also illustrate the spectrum of findings in the cirrhotic liver on dynamic gadolinium-enhanced MR imaging, including retic ular and confluent fibrosis, fatty infiltration, hemochromatosis, regenerat ing nodules, dysplastic nodules, hepatocellular carcinoma, and sequela of p ortal hypertension.
