Objective To explore the clinical value of ultrasound guided biopsy in the diagnosis of thyroid micro carcinoma . Methods 150 patients who were suspected to have thyroid nodules on thyroid ultrasound examination in recent years were enrolled for the study .They all went first for ultrasound guided biopsy and then for surgical resected pathological examination .Results 51 cases with confirmed cancer on ultrasound guided biopsy underwent surgical resected pathological examination ,3 cases were missed diagnosis .Surgical findings revealed carcinoma with diameter greater than 1 cm in 24 cases ,follicular carcinoma and medullary car-cinoma in 2 cases .Carcinoma with diameter less than 1 cm were revealed in 30 cases of papillary carcinoma .There were 2 male and 28 female patients ,aged range from 15-40 years having mean age of (27 .5 ± 1 .3) years .The accuracy of ultrasound guided biop-sy reached up to 90 .0% .Conclusion Ultrasound guided biopsy has high accuracy in diagnosing thyroid micro carcinoma preoperatively .%目的：探讨超声引导下穿刺活检在甲状腺微小癌诊断中临床价值。方法选择因甲状腺超声诊断为甲状腺可疑结节在该院住院的患者150例，所有患者均先在超声引导下穿刺活检，然后经手术切除行病理检查确诊。结果51例穿刺诊断癌者为手术活检证实，漏诊3例。手术所见54例甲状腺癌患者中，直径大于1 cm者24例，滤泡性癌及髓样癌各2例；直径小于1 cm者30例，均为乳头状癌，男2例，女28例，年龄15～40岁，平均（27．5±1．3）岁。经超声引导下穿刺活检准确率为90．0％。结论在超声引导下穿刺活检对甲状腺微小癌的诊断正确率高，是术前获取病理诊断有效的方法。
