超声与磁共振成像诊断肝硬化门静脉高压症图像特征分析

Analysis of Image Features of Ultrasonography and MRI in the Diagnosis of Liver Portal Hypertension in Cirrhosis

目的:分析超声与磁共振成像(MRI)诊断肝硬化门静脉高压症图像特征及诊断价值。方法:随机选取长葛市人民医院2019年1月—2020年2月收治的疑似肝硬化门静脉高压症患者150例,分别接受超声与MRI诊断,并分析其诊断价值。结果:病理结果显示,150例患者中有123例为肝硬化门静脉高压症,比例为82%。MRI诊断肝硬化门静脉高压症阳性率、准确率高于超声诊断(P<0.05),假阳性率及假阴性率低于超声诊断(P<0.05)。结论:超声及MRI均能测量肝硬化门静脉高压症血流动力学指标,其中MRI能直接反映门静脉狭窄程度,从而准确诊断肝硬化门静脉高压症。

Objective:To analyze the value of ultrasonography and MRI in the diagnosis of liver portal hypertension in cirrhosis.Methods:150 patients with suspected portal hypertension from January 2019 to February 2020 were randomly selected to receive ultrasound and MRI diagnosis respectively,and their diagnostic value was analyzed.Results:The pathological results showed that 123 of the 150 patients were cirrhotic portal hypertension,accounting for 82%.The positive rate and accuracy of MRI were higher than that of ultrasound(P<0.05),while the false positive rate and false negative rate were lower than that of ultrasound(P<0.05).Conclusion:Both ultrasound and MRI can measure the hemodynamic index of portal hypertension in cirrhosis,and MRI can directly reflect the degree of portal vein stenosis,so as to accurately diagnose portal hypertension in cirrhosis.
