目的总结分析甲状腺结节的超声图像特征，提高临床诊断水平。方法回顾分析本院2009年1月～2010年12月收治的42例经手术和（或）病理学检查诊断明确的甲状腺结节患者的高频彩色多普勒超声图像特点。结果42例甲状腺结节中恶性者3例，良性病变者39例，其中结节性甲状腺肿32例，甲状腺腺瘤7例。结论超声检查可明确诊断甲状腺结节的数目和定位，具有经济方便、操作直观便捷、分辨率强和准确性高等优点．不失为早期发现和正确评估甲状腺结节性质的首要方法。

Clinical analysis of 42 patients with thyroid nodules examined by high frequency ultrasound

Objective To analyze and summarize the image characteristics of thyroid nodule examined by ultrasound in order to improve the levels of clinical diagnosis. Methods The image characteristics of high frequency color doppler ultrasound from 42 patients admitted into our hospital from January 2009 to December 2010 and diagnosed as thyroid nodule by surgery and/or pathological examination were retrospectively analyzed. Results Among 42 participants, there were 3 malignant cases and 39 benign ones. The latter were composed of nodular goiter （n = 32） and thyroid adenoma （n = 7）. Conclusion The uhrasonic examination can make a definite diagnosis of the number and position of thyroid nodule with some advantages of cheapness and convenience, easy operation, strong distinguishability, and accuracy, which is the principal method for early detection of thyroid nodule and proper evaluation of its property.
