The use of magnetic resonance imaging (MRI) as a diagnostic test for cirrhosis is uncertain. MRI differentiates [[Regeneration|regenerating]] or [[Dysplasia|dysplastic]] [[Nodule (medicine)|nodules]] and [[hepatocellular carcinoma]]. MRI is best used as a follow-up study to determine whether [[Lesion|lesions]] have changed in appearance and size. MRI may accurately diagnose cirrhosis and determines disease severity. Decreased signal intensity on MRI may also reveal an [[iron]] overload and provides an estimate of the [[Liver|hepatic]] [[iron]] concentration. [[Magnetic resonance angiography|MR angiography]] is more sensitive than [[ultrasonography]] in diagnosing complications of cirrhosis such as [[portal vein]] [[thrombosis]].
