摘要
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 sonographic features of papillary thyroid carcinomas in order to improve its diagnosis.Methods Preoperative sonography of 53 patients with thyroid carcinomas comfirmed by pathology were analyzed retrospectively.Some features were observed and analyzed included the magnitude,boundary,calcification,the quantity,resistance index of blood vessel and wheher with lymph tumescence on the neck or not.Results The characteristic appcarance of papillary thyroid carcinoma＇s B modlc and color Dopplcr flow was diverse,but the calcification and low echoes in high frequency ultrasonography may be an important diagnostic indicator for thyroid carcinomas.Conclusions Calcification and low echoes in high frequency ultrasonography are important to diagnose thyroid carcinomas.More plentiful degree of color flow is helpful to improve the ultrasound diagnostic accuracy of thyroid carcinomas excepted specificity.
