Rupture of gastroesophageal varices is a dreaded complication of liver cirrhosis. Once ruptured, overall mortality is ~34%. Endoscopy is the only tool currently available to stratify the risk of rupture in patients with varices. Recently developed approach for 4D-flow-MRI allow for comprehensive mapping of hepatic vessels as well as quantitative flow measurements. We demonstrate here that 4D-flow-MRI enables detection of alteration of flow dynamics in the portal system caused by cirrhosis as well as the visualization of gastroesophageal varices. Flow measurements by 4D-flow-MRI are useful for stratification of variceal risk in patients with cirrhosis.
