摘　　要：目的比较剪切波弹性成像与^(18)F-FDG PET/CT显像诊断甲状腺微小癌的价值。方法回顾性分析经病理证实的甲状腺小结节患者超声剪切波弹性成像及^(18)F-FDG PET/CT显像资料,计算并比较2种方法诊断甲状腺微小癌的灵敏度、特异度、准确率、阳性预测值及阴性预测值。结果 48个甲状腺小结节中,37个为恶性结节,11个为良性结节,剪切波弹性成像与^(18)F-FDG PET/CT显像诊断甲状腺微小癌的灵敏度、特异度、准确率、阳性预测值及阴性预测值结果分别为91.89%(34/37)、81.82%(9/11)、89.58%(43/48)、94.44%(34/36)、75.00%(9/12)和29.73%(11/37)、72.73%(8/11)、39.58%(19/48)、78.57%(11/14)、23.53%(8/34);两种方法的灵敏度、准确率及阴性预测值差异有统计学意义(P均<0.05),特异度、阳性预测值差异无统计学意义(P均>0.05)。结论剪切波弹性成像对甲状腺微小癌的诊断价值优于^(18)F-FDG PET/CT。Objective To compare the diagnostic value of shear wave elastography and 18 F-FDG PET/CT imaging in diag- nosis of thyroid microcarcinoma. Methods Shear wave elastography and 18F_FDG PET/CT data of patients with thyroid nodules confirmed by pathology were analyzed retrospectively. The sensitivity, specificity, accuracy, positive and negative predictive value of the two methods in diagnosis of malignant thyroid micronodules were compared. Results In all of the 48 micronodules, 37 were malignant, 11 were benign. The sensitivity, specificity, accuracy, positive predictive value and neg ative predictive value of shear wave elastography and 18F-FDG PET/CT were 91.89% （34/37）, 81.82% （9/11）, 89.58% （43/48）, 94.44% （34/36）, 75.00% （9/12） and 29.73% （11/37）, 72.73% （8/11）, 39.58% （19/48）, 78.57% （11/ 14）, 23.53% （8/34）, respectively. The sensitivity, accuracy and negative predictive value between the two methods had statistical difference （all P〈0.05）, and the specificity and positive predictive value between the two methods had no statis tical difference （both P〉0.05）. Conclusion Compared to 18F-FDG PET/CT imaging, the diagnositic value of shear wave elastography in diagnosis of thyroid microearcinoma has obvious advantages.
