【摘要】 目的 探討彩色多普勒超聲對臨床甲狀腺良惡性結節的診斷價值。 方法 對2007-2010年105例經手術病理證實的甲狀腺結節患者資料進行回顧性分析，總結其聲像圖特征。 結果 105例患者中，良性結節71例，甲狀腺癌34例，超聲診斷符合率81.9%，誤診18例（17.1%）。 結論 彩色多普勒超聲是診斷甲狀腺結節的首選影像學檢查方法，但對良惡性結節的鑒別及微小癌的診斷有局限性。【Abstract】 Objective To evaluate the value of color Doppler flow imaging in diagnosis of benign and malignant thyroid nodules. Methods We retrospectively analyzed the clinical data of 105 patients with thyroid nodules confirmed by pathology between 2007 and 2010 and summarized the ultrasonography results. Results Among the 105 cases, 71 were benign nodules and 34 were malignant tumors. The overall diagnostic accordance rate was 81.9% with 18 cases (17.1%) of misdiagnosis. Conclusion Ultrasonography is the first imaging modality for thyroid nodule examination, but it is limited in the diagnosis of microcarcinoma and in distinguishing malignant from benign nodules in the same thyroid.
