摘　　要：目的探讨磁敏感加权成像在肝硬化结节多步癌变中的临床应用,旨在能够更早发现癌前病变、小肝癌。方法回顾性分析经病理、手术证实的45例肝硬化患者结节的MRI平扫、增强及DWI、SWI图像,分析不同性质结节的信号变化。结果所有序列共检出结节76个,其中43个RN(SWI呈低信号43个),21个DN(SWI呈低信号15个、呈高信号6个),12个s HCC(SWI呈高信号11个、呈低信号1个)。结论 SWI可以从不同性质结节内铁含量变化的角度进行评价,为癌前病变与小肝癌的进一步鉴别诊断提供新的影像依据。Objective To study the clinical application of magnetic sensitive weighted imaging in liver cirrhosis nodule multistep canceration,so as to find in the early precancerous lesions and small hepatocellular carcinoma. Methods The MRI images including scanning,enhanced scanning,DWI and SWI of 45 patients with cirrhotic nodules by pathology and operation were retrospective analyzed and drawed a conclusion for signal variation with different nature of the nodules. Results All the sequences detected 76 nodules,including RN of 43（ 43 showed low signal with SWI）,DN of 21（ 15 showed low signal,6 showed high signal with SWI）,s HCC of 12（ 1 showed low signal,11 showed high signal with SWI）. Conclusion The SWI sequence can evaluate from the angle of the nodular iron content in different nature,which can provide a new image to the little further differential diagnosis of small hepatocellular carcinoma and precancerous lesions.
