甲状腺结节性病变的超声诊断进展

目的：探讨甲状腺结节性病变的分类、临床鉴别诊断、超声诊断及鉴别诊断价值以及超声引导下细针穿刺细胞学检查(FNAC)的临床意义。方法：查阅了大量有关文献，经过对比、分析和归纳。结果：甲状腺结节性病变的患病率随年龄增长逐年上升，二维超声与彩色多普勒超声检查可检测出微小病灶，形象描述病灶的血供情况。FNAC损伤小，可以迅速准确诊断。结论：高分辨率超声引导下FNAC可以增加甲状腺良恶性病变的诊断准确率，是目前诊断甲状腺结节的最佳方法。

Progress of Ultrasonography in The Diagnosis of Thyroid Nodules

Objective:To inuestigate the classification,clinical differential diagnosis,the value of ultrasonic diagnosis and differential diagnoisis,and the clinical significance of the ultrasound-guided fine-needle aspiration (FNAC) in thyroid nodules. Method: Consulting many related references to compare,analyze and sumup them. Result: The mobility rate of thyroid nodules increased with the age year by year.Two-dimensional ultrasonography could detect the small lesions and color dupplrimaging could display the blood supply for nodules.Ultrasound-guided FNAC was a minitrauma,rapidly and accurately diagnosic method. Conclusion: Well-resolving ultrasould-guided FNAC can provide higher diagnosic rate for differentiating between malignant lesions and benign ones.It is the best method for diagnosing thyroid nodules.
