摘　　要：目的探讨3.0MR对肝硬化结节与小肝癌的鉴别诊断价值。方法选择经临床病理证实为肝硬化结节(46例,53个病灶)和小肝癌(23例,23个病灶)的患者为研究对象,对所有患者均实施3.0MR检测,对比两组患者检测后影像学图像及患者T1W1、T2W2、Gd-DRPA动态增强扫描信号状况。结果①76个病灶均可见再生性结节,肝硬化组患者平均病灶大小大于小肝癌组(P<0.05);②肝硬化组患者T1W1稍高信号及等信号呈现率高于小肝癌组患者,等信号或低信号呈现率低于小肝癌组患者(P<0.05);③肝硬化患者T2W1低信号呈现率小于小肝癌组患者,等信号、高信号或稍高信号呈现率低于小肝癌组患者(P<0.05);④肝硬化患者Gd-DTPA动态增强缓升速降病灶占94.34%(50/53),小肝癌患者速升速降病灶占82.61%(19/23);结论肝硬化结节与小肝癌患者3.0MR检测结果具有较大的差异,可根据结节大小、信号改变、信号强度等加以区分,有利于疾病的鉴别诊断。Objective To explore the value of 3.0 MR in differential diagnosis of cirrhosis nodules and small hepatocellular carcinoma.Methods Patients with cirrhosis nodules(46 cases,53 lesions)and small hepatocellular carcinoma(23 cases,23 lesions)confirmed by clinical pathology were selected as subjects.All patients were examined by 3.0 MR.The imaging images and dynamic enhanced scanning signals of T1W1,T2W2 and Gd-DRPA were compared between the 3 groups.Results①Regenerative nodules were found in all 76 lesions,and the average size of lesions in cirrhosis group was larger than that of small hepatocellular carcinoma group(P<0.05).②The T1W1 signal and iso-signal presentation rate in cirrhosis group was higher than that of small hepatocellular carcinoma group,and the iso-signal or low-signal presentation rate was lower than that of small hepatocellular carcinoma group(P<0.05).③The low-signal presentation rate of T2W1 in cirrhosis group was lower than that of small hepatocellular carcinoma The rate of iso-signal,hyper-signal or slightly hyper-signal presentation was lower than that of small hepatocellular carcinoma group(P<0.05).④The rate of slow-increasing and slow-decreasing lesions of Gd-DTPA dynamic enhancement was 94.34%(50/53)in patients with cirrhosis and 82.61%(19/23)in patients with small hepatocellular carcinoma.Conclusion The results of 3.0MR in patients with cirrhosis nodules and small hepatocellular carcinoma are quite different,which can be differentiated according to nodule size,signal changes and signal intensity,which is helpful for the differential diagnosis of the disease.
