目的探讨乳头状甲状腺癌的二维及彩色多普勒超声表现特征。方法选取53例乳头状甲状腺癌患者的术前超声影像,分析肿块的大小、形态、边界、钙化、内部血流情况、阻力指数以及是否有颈部淋巴结转移,记录并分析其特异性。结果乳头状甲状腺癌二维及血流显像多种多样,低回声结节及结节内砂砾状钙化在乳头状甲状腺癌超声诊断中特异性较高。结论低回声结节及结节内砂砾状钙化是超声诊断乳头状甲状腺癌的重要指标,而彩色血流丰富程度等其他指标对诊断乳头状甲状腺癌无明显特异性。
Objective To investigate the features of papillary thyroid carcinoma by two-dimensional and color Doppler sonography. Methods Fifty-five patients with papillary thyroid carcinoma underwent preoperative ultrasonography. Size, shape, border, calcification, internal blood flow, resistance index and cervical lymph node metastasis were analyzed. The specificity and specificity were recorded and analyzed. Results Two-dimensional papillary thyroid carcinoma and blood flow imaging varied, hypoechoic nodules and nodular calculi in papillary thyroid carcinoma ultrasound diagnosis of high specificity. Conclusion The hypoechoic nodules and nodules of grainy calcification are important indicators for the diagnosis of papillary thyroid carcinoma by ultrasound. However, other indexes such as the abundance of color blood flow have no obvious specificity for the diagnosis of papillary thyroid carcinoma.
