目的分析彩色多普勒超声诊断甲状腺结节的临床价值。方法回顾性分析接受手术治疗的126例甲状腺结节患者的术前彩色多普勒超声影像学结果,评估彩色多普勒超声诊断准确率,分析良、恶性结节彩色多普勒超声的不同特征。结果与术后病理结果对比,彩色多普勒超声诊断准确率为90.80%,误诊率为9.20%。恶性甲状腺结节多可见实性、边界不清晰、低回声及微小钙化等影像学特征,良、恶性结节在内部结构回声、形态、边界及钙化发生率比较差异有统计学意义(P<0.05)。结论良、恶性甲状腺结节的彩色多普勒超声诊断特征明显,彩色多普勒超声诊断准确率较高,可为甲状腺结节的临床诊断与良恶性鉴别提供可靠依据。
Objective To analyze the clinical value of color Doppler sonography in the diagnosis of thyroid nodules. Methods A retrospective analysis of 126 cases of thyroid nodules undergoing surgery for preoperative color Doppler ultrasound imaging results to assess the accuracy of color Doppler ultrasound diagnosis of benign and malignant nodules of different characteristics of color Doppler ultrasound . Results Compared with postoperative pathological results, the diagnostic accuracy of color Doppler ultrasound was 90.80% and the rate of misdiagnosis was 9.20%. Malignant thyroid nodules with more visible solidity, unclear boundaries, hypoechoic and microcalcifications and other imaging features, benign and malignant nodules in the internal structure of the echo, morphology, border and the incidence of calcification was statistically significant difference (P <0.05 ). Conclusion The diagnostic characteristics of color Doppler sonography of benign and malignant thyroid nodules are obvious. The diagnostic accuracy of color Doppler ultrasonography is high, which can provide a reliable basis for the clinical diagnosis and benign and malignant differentiation of thyroid nodules.
