甲状腺结节核素显像的临床价值

Clinical Value of Nuclide Scintigraphy in 180 Patients with Thyroid Nodules

目的:评价甲状腺显像鉴别诊断甲状腺结节良、恶性的临床价值。方法:180例甲状腺结节患者行甲状9mTcO4-显像,并将其与病理结果进行对比研究。结果:甲状腺结节显像呈冷结节者158例(87.8%),温结节者7例(3.9%),热结节者3例(1.7%),甲状腺不显影或显影极淡者12例(其病理诊断为“亚急性甲状腺炎”6.7%)。冷结节癌发生率18.4%(29/158例),1例热结节手术病理诊断乳头状癌0级~1级。良、恶性甲状腺结节患者在甲状腺功能及大小上差异有显著性(χ2=5.70,11.49;P<0.05)。结论:甲状腺核素显像仅从影像特性去区分良、恶性还很困难,可结合其他检查作出初步诊断。

Objective To assess the clinical value of thyroid scintigraphy in the differential diagnosis of benign and malignant thyroid nodular lesions. Methods 180 patients with thyroid nodules were examined with 9m TcO4-thyroid imaging. The results were compared with the pathologic findings. Results Of 180 patients with thyroid imaging, 158 showed cold nodules (87.8%), 7 showed warm nodules (3.9%) and 3 with hot nodules (1.7%), 12 cases who showed very light images or even nonvisualized gland were proved to have sab...
