Overview
MRI
The role of magnetic resonance imaging (MRI) in the diagnosis of cirrhosis is unclear. Despite much enthusiasm about the potential of MRI in the evaluation of the cirrhotic patient, its use today is limited by expense, patient intolerability, and the ability to obtain information provided by MRI through other means.
Some authors report that MRI can accurately diagnose cirrhosis and provide correlation with its severity. [1][2][3] One study found the sensitivity and specificity of an MRI scoring system in distinguishing Child-Pugh grade A cirrhosis from other grades to be 93 and 82 percent, respectively. [1] MRI may also reveal iron overload and provide an estimate of the hepatic iron concentration. MR angiography is more sensitive than ultrasonography in diagnosing complications of cirrhosis such as portal vein thrombosis. [4]
