摘　　要：目的:对比分析^(99m)TcO_4^-唾液腺显像与常规MRI和CT在评价腮腺Warthin's瘤中的准确性。方法:对78例临床疑诊腮腺Warthin's瘤的患者进行^(99m)TcO_4^-唾液腺显像,同时对其中61例患者进行腮腺CT或MRI检查(以下简称常规检查组),与病理结果进行对照,分别得出各自的诊断效能。采用受试者工作特征曲线对比分析^(99m)TcO_4^-唾液腺显像组与常规检查组诊断的准确性,并用χ~2检验对比两组的诊断效能。结果:^(99m)TcO_4^-唾液腺显像的灵敏度、特异性、阳性预测值、阴性预测值分别为94.12%、85.19%、92.31%、88.46%,常规检查组的灵敏度、特异性、阳性预测值、阴性预测值分别为28.26%、53.33%、65.00%、19.51%,两者差异有统计学意义(P<0.05)。受试者工作特征曲线中^(99m)TcO_4^-唾液腺显像组的曲线下面积为0.929,常规检查组的曲线下面积为0.496。结论:^(99m)TcO_4^-唾液腺显像诊断腮腺Warthin's瘤准确性高,有重要的临床应用价值。Objective To compare and analyze the accuracy of ^99mTcO4^--salivary gland imaging and conventional examinations（MRI and CT） in the diagnosis of parotid Warthin＇s tumor.Methods Among the 78 patients with suspected Warthin＇s tumor in the parotid gland who were treated with ^99mTcO4^--salivary gland imaging,61 patients underwent parotid gland CT or MRI examinations（conventional examination group）.The results of ^99mTcO4^--salivary gland imaging and conventional examination were compared with pathological results to obtain the diagnostic efficiency.The diagnosis accuracy of9 ^99mTcO4^--salivary gland imaging group and conventional examination group were analyzed with receiver operating characteristic（ROC） curve,and the diagnostic efficiency of the two groups was compared with χ-2 test.Results The sensitivity,specificity,positive predictive value and negative predictive value of ^99mTcO4^--salivary gland imaging group were 94.12%,85.19%,92.31% and 88.46%,respectively,and those of conventional group were 28.26%,53.33%,65.00% and 19.51%,respectively,with statistical significance between the two groups（P〈0.05）.The area under the ROC curve in ^99mTcO4^--salivary gland imaging group and conventional examination group was 0.929 and 0.496,respectively.Conclusion Compared with conventional examination, ^99mTcO4^--salivary gland imaging achieves higher accuracy on the diagnosis of Warthin＇s tumor in the parotid gland.
