目的:探究肝硬化结节患者核磁共振成像临床分析。方法:选取2012年7月-2013年6月我院收治的31例肝硬化结节患者,均进行核磁共振成像检查,并对临床资料进行回顾性分析。结果:31例肝硬化结节患者在核磁共振成像中表现为T1加权像(T1WI)等或稍高信号,T2加权像(T2WI)为等低信号。增强门静脉扫描与肝组织强化下进行对比呈低信号结节,动脉无强化。合并肝细胞癌为5例患者,T1WI呈等或稍低信号,T2WI偶会出现高或稍高信号。T1WI和T2WI诊断后7例患者的结节周围产生假包膜。结论:核磁共振成像能对肝硬化患者再生结节进行良恶鉴定,并对恶性结节作出疗效诊断。
Objective: To investigate the clinical analysis of magnetic resonance imaging in patients with cirrhosis and nodules. Methods: Totally 31 patients with cirrhosis who were treated in our hospital from July 2012 to June 2013 were examined by MRI, and the clinical data were retrospectively analyzed. Results: Twenty-one patients with cirrhotic nodules showed T1WI or slightly higher signal in MRI and T2-weighted T2WI signal. Enhanced portal vein scan contrast with liver tissue showed low signal nodules, no enhancement of the arteries. Hepatocellular carcinoma with 5 patients, T1WI was equal or slightly lower signal, T2WI even higher or higher signal appears. False envelopes were produced around the nodules in 7 patients after T1WI and T2WI diagnosis. Conclusion: MRI can identify the benign and malignant regenerative nodules of patients with cirrhosis and make the diagnosis of malignant nodules.
