TIPS, ascites drainage), as well as chemoembolisation or radiofrequency ablation of hepatocellular carcinoma. Interventional radiology can be very helpful for the treatment of portal hypertension and its complications (e.g. One of the key roles of diagnostic radiology is the detection of hepatocellular carcinoma (six-monthly ultrasound should be done for surveillance as per 2018 AASLD (American Association for the Study of Liver Diseases) guidelines in cirrhotic patients to screen for hepatocellular carcinoma development) 15. Treatment depends on the underlying etiology and presence of complications.

MR angiography or a balanced steady-state free precession sequence may also be used to assess portal vein patency and portosystemic collaterals. T2: typically mildly or moderately hyperintense High-grade nodules will resemble hepatocellular carcinomas 9 Low-grade nodules will resemble regenerative nodules Maybe of low or high grade, and thus have a variable appearance No early enhancement and washout as most supply is from the portal vein 7,9 Regenerative nodules (or cirrhotic nodules) Morphologic changes (same as on CT and ultrasound) MRI is also insensitive in early cirrhosis but has a significant role in screening cirrhotic livers for small hepatocellular carcinomas (see LI-RADS). Upper abdominal lymphadenopathy in end-stage disease 16 Portal venous thrombosis +/- cavernous transformationĮnlarged superior mesenteric vein and splenic vein In advanced cirrhosis, nodular margin and lobar hypertrophy/atrophy may be demonstrated (see above) Predominantly portal venous supply to dysplastic nodules Parenchymal heterogeneity both on the pre and post intravenous contrast scans Siderotic nodules (minority): hyperdense due to accumulation of iron 6 Regenerative nodules (majority): isodense/hyperdense to the rest of liver Sonoelastography may also be useful to assess the amount of liver fibrosis 12. Suggested values for diagnosis are:Ĭontrast-enhanced ultrasound may have a role in the diagnosis of cirrhosis, as diminished mean hepatic venous transit time is similar to that of perfusion CT 13. Increased velocity (compensating for decreased portal vein flow)

Alcoholism and viral hepatitis from intravenous drug use or in an endemic region are the common causes. The demographics of cirrhosis reflect the underlying causes.
