彩色多普勒血流对良恶性甲状腺结节的诊断价值

目的 探讨彩色多普勒血流对良恶性甲状腺结节的诊断价值。方法 选取2018 年1 月—2018 年9 月在杭州市中医院行甲状腺结节手术的119 例患者,回顾性分析患者相关资料和检查结果。以术后病理为金标准,将患者分为良性组和恶性组。观察两组患者的结节大小、分布、形态、彩色多普勒超声声像特点及血流信号值。结果 以术后病理为金标准,彩色多普勒超声的诊断的准确率为81.05% ;两组患者结节大小、位置及数量比较,差异有统计学意义（P <0.05）;两组患者的回声、边缘、钙化、强回声及包膜侵犯比较,差异有统计学意义（P <0.05）;两组患者的血流分值比较,差异有统计学意义（P <0.05）。结论 彩色多普勒血流信号对甲状腺良恶性结节具有较好的诊断价值。

The diagnostic effect of color Doppler ultrasoundon differentiation of thyroid nodules

Objective To investigate the application of color doppler ultrasound in the benign or malignantthyroid nodules. Methods A total of 119 patients who underwent surgeries in our hospital from January toSeptember 2018, and the related data and results of patients were retrospectively analyzed. The patients were dividedinto benign group (24 cases) and malignant group (95 cases) with postoperative pathology as the gold standard. Thesize, distribution, morphology, color Doppler ultrasonographic features and blood flow signal values of the nodulesin the two groups were observed and statistically analyzed by SPSS 20.0. Results The diagnostic accuracy of colorDoppler ultrasonography was 81.05%. There were significant differences between benign and malignant nodulesin size, location and number of nodules, echo, margin, calcification, strong echo, encapsulation invasion and bloodflow signal value (P < 0.05). Conclusions Color Doppler flow imaging has good diagnostic value for benign andmalignant thyroid nodules.
