应用彩色多普勒超声诊断结节性甲状腺病变

目的 探讨彩色多普勒超声鉴别诊断结节性甲状腺病变的意义。方法 回顾性分析病理或细胞学证实的结节性甲状腺病变74例二维超声和彩色多普勒超声（CDFI）表现。结果 结节性甲状腺肿、甲状腺腺瘤和腺癌超声和血流图像表现有一定规律性，定位准确，敏感性强。结论 彩色多普勒超声是诊断结节性甲状腺病变首选检查方法。

Use of color Doppler flow image to differentiate tuberous pathological changes of Thyroid

Objective To evaluate the significance of color Doppler flow image (CDFI) in differentiating the tuberous pathological changes of thyroid. Methods Retrospective study was performed by reviewing the findings in the planar ultrasonographs and CDFI images of 74 cases of tuberous pathological changes of thyroidea, which had been identified by pathology and cytology. Results The relatively regular features in appearance and blood flow were summarized representing the varied tuberous thyroid pathologies, i.e. tuberous thyrocele, thyroid adenoma and thyroid carcinoma. These techniques were reliable and sensitive for localizing and differentiating the lesions. Conclusions CDFI is the first choice to diagnose the tuberous pathological changes of thyroid.
