Overview
The use of magnetic resonance imaging (MRI) as a diagnostic test for cirrhosis is uncertain. MRI sometimes differentiates among regenerating or dysplastic nodules and hepatocellular carcinoma, it is best used as a follow-up study to determine whether lesions have changed in appearance and size.
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.
Although MRI sometimes differentiates among regenerating or dysplastic nodules and hepatocellular carcinoma, it is best used as a follow-up study to determine whether lesions have changed in appearance and size. 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 an iron overload and provide an estimate of the hepatic iron concentration.
MRA
Although used rarely, magnetic resonance angiography (MRA) can assess portal hypertensive changes including flow volume and direction, as well as portal vein thrombosis. MR angiography is more sensitive than ultrasonography in diagnosing complications of cirrhosis such as portal vein thrombosis. [4]
Despite the potential of MRI and MRA in the diagnosis and evaluation of patients with cirrhosis, their widespread use is limited by their expense and by the ability of routine ultrasonography with Doppler to obtain adequate information for the diagnosis of cirrhosis and presence of complications.
