【摘要】 目的 探讨二维超声及彩色多普勒超声声像图特征对甲状腺良恶性肿瘤的鉴别诊断价值。 方法 采用二维超声及彩色多普勒超声对136例甲状腺结节的患者进行检查，对各种声像图特征进行统计学分析，全部病例经手术和(或)超声引导下穿刺活检并经病理证实的。 结果 回声情况、周围晕、后方衰减、形态这4项征象对鉴别良恶性肿瘤具有很高的敏感性和特异性。 结论 二维超声及彩色多普勒超声声像图特征对甲状腺良恶性肿瘤的鉴别诊断价值较大。

    【Abstract】 Objective To investigate the value of signs of two-dimensional and color Doppler ultrasonogra-phy in diagnosis of thyroid nodules.Methods 136cases with thyroid nodule confirmed by pathology were investigated by two-dimensional and color doppler ultrasonography，and a series of signs of two-dimensional and color doppler ultrasonography were analyzed.Results echographic texture，halo sign，attenuation and shape have highly sensitivity and specificity for diagnosis of thyroid malignant nodules.Conclusion Signs of two-dimensional and color doppler ultrasonography have important value to predicting in thyroid malignant nodules. ......
