磁共振扩散加权成像在肝硬化分级诊断中的应用研究

Application Study on Liver Cirrhosis Classification Diagnosis of Magnetic Resonance Diffusion-weighted Imaging

目的：探讨磁共振扩散加权成像在肝硬化分级诊断中的应用价值。方法选择2011年1月~2015年6月本院收治的肝硬化患者40例，观察组进行磁共振加权成像检查，对照组则行CT增强扫描，比较在b=200 s/mm2条件下磁共振加权成像肝硬化分级ADC值，并统计两组影像学诊断与病理诊断符合率。结果肝硬化Child分级越高，其ADC值越低（P＜0.05），观察组阳性比例高于对照组（P＜0.05）。结论磁共振加权成像是诊断肝硬化并对肝硬化进行分级的一种有效手段。

Objective To evaluate the value of magnetic resonance diffusion-weighted imaging with liver cirrhosis grading.Methods Selected 40 cases with cirrhotic patients from January 2011 to June 2015 in our hospital,the observation group were weighted magnetic resonance imaging,the control groupwere enhanced underwent CT scans, then magnetic conditions resonance imaging weighted grade ADC value of liver cirrhosis were compared when b=200 s/mm2, and two diagnosis and pathological diagnosis coincidence rate imaging were compared. ResultsThe higher cirrhosis Child classiifcation had lowerADC value （P〈0.05）, the proportion of positive with the observation group was higher than control group （P〈0.05）.ConclusionWeighted MR imaging is an effective means of diagnosis of cirrhosis of the liver and cirrhosis.
