彩色多谱勒超声诊断甲状腺肿块302例分析

目的 探讨超声在甲状腺肿块上的参考价值。方法 回顾性分析我院从1995年2月-2001年1月间，应用高分辨率超声诊断的302例甲状腺肿块的二维超声图象表现和彩色多谱勒特征，并与病理结果对照，结果 本组诊断符合率88.1%，误诊率11.9%。其中甲状腺腺瘤156例，结节性甲状腺肿81例，甲状腺癌42例，多源性病变23例，均误漏诊。结论 高频彩色多谱勒超声在甲状腺肿块的诊断方面具有重要的应用价值。但在鉴别良恶性方面尚无绝对可靠的指征，对多源性甲状腺病变及不典型肿物仅凭二维超声及彩色多谱勒作出定性诊断，尚有一定的局限性。

The analysis of 302 patients of color doppler ultrasonography in diagnosis of thyroid mass

Objective To investigate the value of color doppler ultrasonography diagnosis of thyroid mass.Methods 302 patients confirmed by operation and pathology were examined by two dimensional and color doppler ultrasonography.Results 156 patients were diagnosed to have thyroid adenoma,81 patients nodular goiter,42 patients thyriod adenocarcinoma,and 23 patients multiplex disease(7.5%),all encountering a faulty or omissive diagnosis.Conclusion Two dimensional and color doppler ultrasonography have a vital value in diagonosis of thyroid mass,but they don't have the definite characteristics in identification of benign or malignant thyroid tumor.They also have some limitation in qualitative diagnosis of multiplex thyroid disease and non typical thyroid tumor.
