Abstract:
Portal hypertension is the most common complication of liver cirrhosis. Noninvasive radiological examinations have important values in evaluating liver parenchyma, collateral circulation, and esophagogastric variceal bleeding in liver cirrhosis. Computed tomography (CT) and magnetic resonance imaging (MRI) can reflect the changes in liver morphology, the density and signals of liver parenchyma, and hemodynamics and have important values in disease diagnosis and prognostic evaluation. CT and functional MRI, such as perfusion-weighted imaging, MR elastography, and MR diffusion-weighted imaging, can provide quantitative information and can be applied in the diagnosis of hepatic fibrosis and early-stage liver cirrhosis in clinical practice. CT angiography and MR angiography, especially unenhanced MR angiography, can show the condition of the branches of portal vein, which helps to evaluate the risk of esophagogastric variceal bleeding and detect the markers for early warning. A combination of CT and MRI and evaluation of their potential in clinical application can give full play to the role of radiological examinations in the diagnosis, evaluation, and prognostic analysis of cirrhotic portal hypertension.
