目的：比较多层螺旋 CT与 MRI检查对小肝细胞癌的诊断敏感性。方法2014年6月至2016年6月选择疑似小肝细胞癌患者134例，其中最终经术后病理证实的小肝细胞癌患者62例，134例患者分别行多层螺旋 CT与MRI检查，与病理结果比较，探讨多层螺旋 CT 与 MRI 检查对小肝细胞癌的诊断价值。结果多层螺旋 CT 与MRI平扫的检出率、敏感性比较差异有统计学意义（P ＜0.05），而增强扫描检出率、敏感性比较差异未见统计学意义（ P ＞0.05）。结论 MRI平扫及增强扫描诊断小肝细胞癌的敏感性均高于多层螺旋 CT，且更能清晰显示小肝细胞癌的血流特点，故具有更高临床应用价值。“,”Objective To compare the sensitivity of multi-slice spiral CT and MRI in the examination of small hepato-cellular carcinoma. Methods One hundred and thirty-four cases of suspected small hepatocellular carcinoma from June 2014 to June 2016 were selected,and 62 cases of small hepatocellular carcinoma confirmed by pathology after surgery. All of the 134 patients underwent multi-slice spiral CT and MRI examination,and compared with pathology. Then,the value of multi-slice spiral CT and MRI in the diagnosis of small hepatocellular carcinoma were studied. Results There were signifi-cant differences in the detection rate and the sensitivity between multi-slice spiral CT and MRI plain scan (P 0. 05). Conclusion The sen-sitivity of MRI scan and enhanced scan in the diagnosis of small hepatocellular carcinoma are higher than the multi-slice spiral CT,and can clearly show the flow characteristics of small hepatocellular carcinoma,so it has higher clinical value.
