Overview
The use of magnetic resonance imaging (MRI) as a diagnostic test for cirrhosis is uncertain. MRI differentiates regenerating or dysplastic nodules and hepatocellular carcinoma. MRI is best used as a follow-up study to determine whether 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 hepatic iron concentration. MR angiography is more sensitive than ultrasonography in diagnosing complications of cirrhosis such as portal vein thrombosis.
MRI
Role of MRI in cirrhosis:[1][2][3][4][5][6][7]
- The role of magnetic resonance imaging (MRI) in the diagnosis of cirrhosis is unclear.
- The use of MRI is limited by expense, patient intolerability, and the ability to obtain information provided by MRI through other means.
- MRI differentiates regenerating or dysplastic nodules from hepatocellular carcinoma by accurately determining the nature of focal lesions.[1][2][8][9]
- MRI is used as a follow-up study to determine whether lesions have changed in appearance and size.
- MRI may accurately diagnose cirrhosis and determines disease severity.[10][11][12]
- Decreased signal intensity on MRI may also reveal an iron overload and provides an estimate of the hepatic iron concentration.
MRA
- Magnetic resonance angiography (MRA) may be used to assess portal hypertensive changes including volume and direction of blood flow in the portal vein.
- MR angiography is more sensitive than ultrasonography in diagnosing complications of cirrhosis such as portal vein thrombosis.[13]
- The use of MRA is limited by its expense and the ability of routine ultrasonography with Doppler to obtain adequate information for the diagnosis of cirrhosis and presence of complications.
