摘要
目的：比较超声弹性成像（Ultrasonic elastography，UE）与18F-FDG PET/CT对良、恶性甲状腺结节的鉴别诊断价值。方法：对89例甲状腺结节患者共115个结节作回顾性研究，均已行超声弹性成像及18F-FDG PET/CT检查，以手术病理为金标准，比较UE与18F-FDG PET/CT鉴别诊断甲状腺良恶性结节的敏感性、特异性、准确性。结果：UE与18F-FDG PET/CT诊断甲状腺结节的敏感性、特异性、准确性分别为87.06%，93.05%，72.4%和96.55%，66.28%，73.91%。UE诊断甲状腺良恶性结节的准确性高于PET/CT，差异有统计学意义（χ2=14.29，P<0.05）。结论：UE在鉴别诊断甲状腺良恶性结节方面优于18F-FDG PET/CT。
Abstract
Objective: To compare the value of ultrasonic elastography(UE) with 18F-FDG PET/CT in differentiating benign and malignant thyroid nodules. Methods: Eighty-nine patients with 115 lesions in the thyroid were retrospective studied. All the patients underwent UE and 18F-FDG PET/CT. Pathologic outcome was used as the gold diagnosis criterion. The sensitivity, specificity, accuracy of UE in diagnosing thyroid nodules were compared with 18F-FDG PET/CT. Results: Sensitivity, specificity and accuracy of UE were 87.06%, 93.05% and 72.4%, and that of 18F-FDG PET/CT were 96.55%, 66.28% and 73.91%. The accuracy of UE was higher than 18F-FDG PET/CT in differentiating benign and malignant thyroid nodules(χ2=14.29, P<0.05). Conclusion: UE has better diagnostic value than 18F-FDG PET/CT in differentiating benign and malignant thyroid nodules.
