Cirrhosis of the liver not only increases the risk of liver cancer but also causes portal hypertension, leading to gastrointestinal bleeding, hepatic encephalopathy, ascites, and other complications. The opening of collateral circulation caused by portal hypertension plays an important role in the occurrence and progress of diseases. Therefore, precise diagnosis of collateral circulation (CC) in cirrhotic patients is important for clinical practice. Hereby, we compared quantitative parameters from multiparametric MRI (4D flow, APT, IVIM, T1/T2 mapping) between the CC and non-CC groups in cirrhotic patients, which showed significant differences.
