非酒精性脂肪肝肝细胞肝癌（HCC）的MR诊断

Magnetic resonance diagnosis on non-alcoholic fatty liver hcpatocellular carcinoma

目的观察非酒精性脂肪肝肝细胞肝癌（HCC）的MR诊断表现及检出率。方法对2009年10月至2010年5月在我院确诊为非酒精性脂肪肝肝细胞肝癌的67例患者进行MR检测。结果MR结果显示，67例患者均出现长T1、长T2信号，且对其进行MRI测定后发现其动脉期出现明显强化，而门脉期和平衡期的强化程度则明显下降。部分患者显示出强化的环形肿瘤包膜。MR对于HCC的诊断率为100％。结论非酒精性脂肪肝肝细胞肝癌（HCC）的MR诊断检出率高。

Objective To observe non-alcoholic fatty liver hepatocellular carcinoma （HCC） magnetic reso- nance （MR） diagnostic performance, and detection rate. Method From October 2009 to May 2010 in our hospital, 67 patients were diagnosed with non-alcoholic fatty liver disease in patients with HCC detected by MR. Results According to the results of MR, all 67 patients showed long T1 and long T2 signals, and after MRI determination the arterial phase appeared obviously strengthened, while the portal phase and equilibrium phase enhancement degree decreased. Some patients showed a reinforced annular tumor capsule. According to the results, the diagnosis rate of MR to HCC was 100%. Conclusion MR diagnosis has the high detection rate in non-alcoholic fatty liver HCC.
