【摘要】 目的探讨甲状腺癌的二维和彩色多普勒超声图像特点,提高早期诊断女性甲状腺癌的准确性。方法应用高频超声诊断仪对46例女性甲状腺占位性病变经手术与病理证实为甲状腺癌的声像图进行分析,着重分析肿块内部回声的特点、边缘、彩色血流丰富程度、频谱多普勒中的多项测量指标的变化以及与周围组织的关系。结论肿块形状不规则、轮廓不清晰、向周围组织浸润,内部为实质不均质低回声,可见多发散在的点状、微粒状强回声是超声诊断甲状腺癌的重要声像图特征,而彩色血流丰富情况与颈静脉周围和锁骨上窝内淋巴结肿大有助于超声提高甲状腺癌的诊断准确性。更多还原

【Abstract】 Objective To study the feature of image of Two Dimensional and Color Doppler Ultrasound for Thyroid Carcinoma.To raise the early diagnostic accuracy of Thyroid Carcinoma.Methods Forty-six cases with thyroid disease,confirmed by pathology and operation,were analyzed with high-frequency diasonography.Emphasis is the feature of internal echo of nodus,the borderline,the plentiful degree of color flow,the measuring indexs’change in frequency spectrum Doppler,and relation with surrounding tissue.Conclusion The tumor shows abnormal shape,also unclear outline,and infiltrate surrounding tissue.Parenchymal but no homogeneous low echo can be seen in the internal tumor,the many sporadic punctiform dense echos in the tumor is important features to diagnose Thyroid Carcinoma.The degree of color flow,lymphadenectasis of surrounding jugular vein and supraclavicular fossa make for raising diagnostic accuracy of Thyroid Carcinoma.更多还原
