摘　　要：目的:对MR磁敏感加权对肝硬化背景小肝癌诊断价值进行评价分析,为今后的临床诊断工作,提供有价值的参考信息。方法:收集2012年1月-2016年12月间,临床疑诊肝细胞癌需接受腹部MRI检查的肝脏占位性病变患者65例,双盲法对常规MRI、MRI与MR磁敏感加权联合图像进行阅片,并以病理结果为金标准,对诊断结果进行评价。结果:MRI与MR磁敏感加权联合检测对肝细胞癌的诊断敏感性、特异性、准确性均较常规MRI检测高(P<0.05)。结论:经MRI与MR磁敏感加权联合检测,对于提高肝硬化背景下小肝癌的诊断率,治疗方案选择以及治疗预后评估等,均具有重要意义,值得关注。Objective： To evaluate the diagnostic value of MR susceptibility weighted magnetic resonance imaging in the diagnosis of small hepatocellular carcinoma（HCC） in patients with liver cirrhosis. Methods： From January 2012 to December 2016, clinical suspected hepatocellular carcinoma received abdominal MRI examination in 65 cases of liver occupying lesions were read on conventional MRI, MRI and MR susceptibility weighted images were combined with double blind method, and with pathological results as the gold standard to evaluate the diagnostic results. Results： The sensitivity,specificity and accuracy of MRI combined with MR susceptibility weighted detection for hepatocellular carcinoma were higher than that of conventional MRI（P〈0.05）. Conclusion： The combined detection of MRI and MR magnetic susceptibility is of great significance to improve the diagnosis rate, treatment options and prognosis evaluation of small hepatocellular carcinoma.
