彩色多普勒超声在甲状腺肿瘤诊断中的应用

Study on the clinical application of color Doppler ultrasound in diagnosis of thyroid tumor

目的:探讨彩色多普勒超声(CDFI)在诊断甲状腺肿瘤的应用效果。方法:选取甲状腺肿瘤患者93例,按照其肿瘤良、恶性分为腺瘤组和腺癌组。比较两组患者肿瘤形态学、钙化特性、血液动力学特性。结果:腺瘤组肿瘤形态多表现为边界清晰、边缘较为光滑、回声均匀,而腺癌组肿瘤表现为边界模糊、边缘粗糙、回声不均(P<0.05),囊性变差异无统计学意义(P>0.05);腺瘤组钙化率低于腺癌组(P<0.05),腺瘤组钙化表现为边缘钙化,腺癌组表现为弥散微钙化;腺瘤组收缩期峰值血流速度(PSV)、阻力指数(RI)低于腺癌组(P<0.05),舒张末期血流速度(EDV)无差异(P>0.05)。结论:CDFI对甲状腺肿瘤的早期诊断具有重要应用价值。

Objective To investigate the application of color Doppler ultrasound（ CDFI） in diagnosis of thyroid tumors. Methods93 cases of patients with thyroid cancer were selected and divided into thyroid adenoma group and thyroid carcinoma group according to the benign tumor or malignant tumor the tumor. The tumor morphology characteristics,calcification and hemodynamic characteristics in the patients of two groups were compared. Results The tumor morphology in the patients of the thyroid adenoma group showed the boundary was clear,the edge was smooth and that the echoes were even while the tumor morphology in the patients of the thyroid carcinoma group showed the boundary was fuzzy,the edge was rough and that the echoes were uneven（ P〈0. 05）. There was no significant difference in cystic change（ P〉0. 05）. The calcification rate of the adenoma group was lower than that of the carcinoma group（ P〈0. 05）. Calcification of the adenoma group showed marginal calcification while calcification of the carcinoma group showed micro-calcification. The peak systolic velocity（ PSV） and resistance index（ RI） of the adenoma group was lower than those of the carcinoma group（ P〈0. 05）. There was no difference between end- diastole velocity（ EDV）（ P〉0. 05）. Conclusion CDFI has the most important value in diagnosis of the early thyroid tumor.
