Application of 4D Flow MRI in Quantitative Evaluation of Portal Hypertension in Cirrhosis

肝硬化是慢性肝病的常见终末期表现，门静脉高压症是肝硬化患者最常见、最致命的并发症，门静脉高压症及其并发症是肝硬化患者死亡的主要原因。肝硬化患者在门静脉高压症发展过程中，血流会发生剧烈变化。因此门静脉系统血流动力学的评价在肝硬化病变的诊断与评估起着重要作用。4D Flow MRI是一种能无创性定量评估血流动力学的技术，本文将对目前4D Flow MRI在肝硬化门静脉高压中的应用进行综述。Cirrhosis is a common end-stage manifestation of chronic liver disease, and portal hypertension is the most common and fatal complication in patients with cirrhosis. Portal hypertension and its complications are the main cause of death in patients with cirrhosis. During the development of portal hypertension, patients with cirrhosis may experience significant changes in blood flow. Therefore, the evaluation of portal vein hemodynamics plays an important role in the diagnosis and assessment of liver cirrhosis lesions. 4D Flow MRI is a non-invasive quantitative assessment technique for hemodynamics. In this review, we will summarize the current research progress of 4D Flow MRI in portal hypertension in liver cirrhosis.
