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.
