Synopsis

Keywords: Flow, Velocity & FlowNoninvasive identification of high-risk varices (HRV) in cirrhosis patients is of significantly value because it could help avoid some unnecessary upper gastrointestinal endoscopy and repeat in a short time to evaluate the efficiency of non-selective beta blockers therapy. This study aims to evaluate the value of 4D flow MRI combined with precontrast T1 in identifying HRV. Our results indicated that the model including SMV forward volume, SMV maximum blood flow, precontrast liver T1 mapping, and precontrast spleen T1 mapping could effectively identify HRV of cirrhosis patients.
