摘要
目的 探讨多层螺旋CT(MSCT)联合MRI检查对乙肝肝硬化合并小肝癌的诊断价值.方法 选取70例疑似乙肝肝硬化合并小肝癌患者,所有患者均行MSCT和MRI检查.以病理检查结果为金标准,分析MSCT、MRI单独及联合检查对乙肝肝硬化合并小肝癌的诊断价值.结果 病理检查结果显示,小肝癌61例,非小肝癌(良性肝肿瘤)9例.MSCT检查诊断乙肝肝硬化合并小肝癌的灵敏度为81.97%,特异度为88.89%,准确度为82.86%,阳性预测值为98.04%,阴性预测值为42.11%,与病理检查结果具有中等一致性(Kappa=0.481).MRI检查诊断乙肝肝硬化合并小肝癌的灵敏度为85.25%,特异度为77.78%,准确度为84.29%,阳性预测值为96.30%,阴性预测值为43.75%,与病理检查结果具有中等一致性(Kappa=0.473).MSCT联合MRI检查诊断乙肝肝硬化合并小肝癌的灵敏度为95.08%,特异度为66.67%,准确度为91.43%,阳性预测值为95.08%,阴性预测值为66.67%,与病理检查结果具有较高一致性(Kappa=0.617).结论 MSCT联合MRI检查对乙肝肝硬化合并小肝癌具有较高的诊断价值,可提高诊断灵敏度和准确度,降低漏诊率.
Abstract
Objective To evaluate the diagnostic value of multi-slice spiral CT(MSCT)combined with MRI in hepa-titis B cirrhosis complicated with small liver cancer.Method A total of 70 patients with suspected hepatitis B cirrhosis complicated with small liver cancer were selected.All patients underwent MSCT and MRI examinations.Using pathologi-cal examination results as the gold standard,the diagnostic value of MSCT and MRI single and combined examination in hepatitis B cirrhosis complicated with small liver cancer were analyzed.Result Pathological examination results showed that 61 patients were small liver cancer and 9 patients were not small liver cancer(benign liver tumors).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MSCT in the diagnosis of hepatitis B cir-rhosis complicated with small liver cancer were 81.97%,88.89%,82.86%,98.04%and 42.11%,respectively,which had moderate consistency with pathological examination results(Kappa=0.481).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MRI in the diagnosis of hepatitis B cirrhosis complicated with small liv-er cancer were 85.25%,77.78%,84.29%,96.30%and 43.75%,respectively,which had moderate consistency with patho-logical examination results(Kappa=0.473).The sensitivity,specificity,accuracy,positive predictive value,and positive predictive value of MSCT combined with MRI in the diagnosis of hepatitis B cirrhosis complicated with small liver can-cer were 95.08%,66.67%,91.43%,95.08%and 66.67%,respectively,which had high consistency with pathological ex-amination results(Kappa=0.617).Conclusion MSCT combined with MRI has high diagnostic value in hepatitis B cir-rhosis complicated with small liver cancer,which can improve diagnostic sensitivity and accuracy,and reduce the rate of missed diagnosis.
