摘　　要：目的探讨超声造影(CEUS)和增强计算机体层扫描(CECT)对不同直径肝癌的诊断准确率。方法选取2015年1月至2018年6月间收治的78例疑似肝癌患者作为研究对象,所有患者均行CEUS和CECT检查。以病理检查作为“金标准”,评估不同检查方法诊断肝癌的效能;根据肝癌病灶直径分组,比较CEUS、CECT单独及联合检查对不同直径肝癌的诊断准确率。结果1)CEUS、CECT诊断肝癌灵敏度对比差异无统计学意义(P>0.05),联合检查诊断肝癌灵敏度高于CEUS、CECT单独检查(P<0.05);CEUS、CECT、联合检查诊断肝癌特异度对比差异无统计学意义(P>0.05);CEUS、CECT诊断肝癌准确率对比差异无统计学意义(P>0.05),联合检查、CEUS诊断肝癌准确率对比差异无统计学意义(P>0.05),联合检查诊断肝癌准确率高于CECT(P<0.05);2)CEUS、CECT及联合检查诊断直径<3cm、≥3cm肝癌病灶准确率对比,差异均无统计学意义(P>0.05)。结论CEUS、CECT均是诊断肝癌的有效检查方法,两者联合检查效能更高,但CEUS、CECT单独及联合检查诊断不同直径肝癌准确率差异不显著。Objective To explore the diagnostic accuracy rate of contrast-enhanced ultrasound(CEUS)and contrast-enhanced computed tomography(CECT)for liver cancer of different diameters.Methods A total of 78 patients suspected as liver cancer who were admitted between January 2015 and June 2018 were selected for the study.All patients were examined by CEUS and CECT.Pathological examination was used as the gold standard to evaluate the efficacy of different examination methods for diagnosis of liver cancer.The patients were grouped according to the diameter of liver cancer lesions,and the diagnostic accuracy rates of CEUS,CECT and combined examination for liver cancer of different diameters were compared.Results There was no significant difference in sensitivity of CEUS and CECT in the diagnosis of liver cancer(P>0.05),and the sensitivity of combined diagnosis of liver cancer was higher than that of CEUS or CECT(P<0.05).There was no statistically significant difference in the specificity of CEUS,CECT and combined diagnosis of liver cancer(P>0.05),and there was no significant difference in the accuracy rate of CEUS and CECT in the diagnosis of liver cancer(P>0.05),and there was no significant difference in the accuracy rate of combined diagnosis and CEUS diagnosis of liver cancer(P>0.05),and the accuracy rate of combined diagnosis of liver cancer was higher than that of CECT(P<0.05).There was no significant difference in the accuracy rate of CEUS,CECT and combined diagnosis in the diagnosis of liver cancer lesions with diameter<3cm and diameter≥3cm(P>0.05).Conclusion both CEUS and CECT are effective methods for the diagnosis of liver cancer,and the combination of the two methods has higher efficacy.However,there was no significant difference in the accuracy rate of CEUS,CECT and combined diagnosis in the diagnosis of liver cancer of different diameters.
