目的:探讨甲状腺癌二维和彩色多普勒超声图像(CDF I)特点,提高早期诊断和鉴别诊断的准确性。方法:对经手术病理证实的32例甲状腺癌患者的术前超声结果进行回顾性分析。结果:本组32例病例中,单个肿块22例(68.7%),伴结节性甲状腺肿2例,低回声实性结节28例(87.5%),结节中检出有砂砾样钙化者20例(62.5%),血流成像显示Ⅲ型22例(6%),血流为高阻力型者(R I>0.7)19例(59%),淋巴结转移11例(34%)。结论:甲状腺癌二维声像图结合CDF I表现,将有助于提高甲状腺癌诊断的准确性。
Objective: To investigate the characteristics of two-dimensional and color Doppler ultrasonography (CDF I) in thyroid cancer and to improve the accuracy of early diagnosis and differential diagnosis. Methods: Thirty-two cases of thyroid cancer confirmed by surgery and pathology were retrospectively analyzed. Results: Twenty-two patients (68.7%) with nodular goiter, 28 cases with hypoechoic nodules (87.5%), and 33 cases with gravel-like calcification Twenty - two cases (62.5%) showed blood flow imaging in 22 cases (6%) of type Ⅲ, 19 cases (59%) had high blood flow resistance (RI> 0.7) and 11 cases (34%) of lymph node metastasis. Conclusion: The two-dimensional sonography of thyroid cancer combined with CDF I will help to improve the diagnostic accuracy of thyroid cancer.
