目的分析甲状腺乳头状癌及微小乳头状癌的超声特征。方法乳头状癌组12例，共16个结节，微小乳头状癌组23例，共29个结节，分析结节内部低回声、微钙化、边缘不规则、Ⅲ型血流信号及甲状腺最大横径与纵径比值（A/T）≥1对甲状腺乳头状癌及微小乳头状癌的诊断价值。结果结节Ⅲ型血流信号对甲状腺乳头状癌的诊断价值最高， A/T≥1对甲状腺微小乳头状癌的诊断价值最高。结论 A/T≥1有助于预测甲状腺微小乳头状癌，结节内紊乱血流信号有助于预测甲状腺乳头状癌。

Objective To explore the sonographic features of thyroid papillary carcinomas and papillary microcarcinoma. Methods 2D ultrasonography and color Doppler flow imaging characteristics of 12 patients with thyroid papillary carcinoma (16 nudules) and 23 patients with papillary microcarcinoma ( 29 nudules) were summarized, the diagnostic value of internal hypoechoic area, microcalcification, irregular border, type Ⅲ blood flow signals, and A/T≥1 was analyzed. Results Type Ⅲ blood flow signals had the highest diagnostic value for papillary carcinomas, and A/T≥1 had the highest diagnostic value for thyroid papillary microcarcinoma. Conclusion A/T≥1 can help to predict thyroid papillary microcarcinoma, indiscriminate blood flow signals in the nodules can help to predict thyroid papillary carcinoma.
