肝硬化结节与小肝癌的多层螺旋CT、MRI鉴别诊断价值

The Value of MSCT and MRI in Differential Diagnosis of Cirrhotic Nodules and Small Hepatocellular Carcinoma

目的探讨肝硬化结节与小肝癌的多层螺旋CT(MSCT)、磁共振成像(MRI)鉴别诊断价值。方法回顾性分析87例(109个病灶)肝硬化患者的临床资料,所有患者均行MSCT、MRI检查,以手术病理结果作为金标准。比较MSCT、MRI检查的诊断结果,比较两种方法的灵敏度、特异度、准确率、阴性阳性预测值差异。结果MRI检查的特异度(94.03%)、准确率(93.58%)、阳性预测值(90.70%)均高于MSCT(94.03%、93.58%、73.91%)(P均<0.05),两种检查的敏感度、阴性预测值(MRI:92.86%,95.45%;MSCT:80.95%、87.30%)差异无统计学意义(P>0.05)。结论肝硬化结节与小肝癌的诊断中,MRI与MSCT相比具备更高的鉴别诊断价值。

Objective To investigate the differential diagnosis value of multi-slice spiral CT(MSCT)and magnetic resonance imaging(MRI)between cirrhotic nodules and small liver cancer.Methods The clinical data of 87 cases(109 lesions)with cirrhosis were retrospectively analyzed.All patients underwent MSCT and MRI examination,and the operative pathological Results were used as the gold standard.The diagnostic Results of MSCT and MRI were compared,and the sensitivity,specificity,accuracy,negative and positive predictive values of the two Methods were compared.Results The specificity(94.03%),accuracy(93.58%)and positive predictive value(90.70%)of MRI examination were higher than that of MSCT(94.03%,93.58%,73.91%)(P<0.05).The sensitivity and negative predictive value(MRI:92.86%,95.45%)of the two examinations were higher than that of MSCT(94.03%,93.58%,73.91%).MSCT:(80.95%,87.30%)showed no significant difference(Pa ll>0.05).Conclusion MRI has higher differential diagnostic value than MSCT in the diagnosis of cirrhosis nodules and small hepatocellular carcinoma.
