彩色多普勒超声对甲状腺良恶性结节患者的鉴别诊断分析

Differential Diagnosis of Color Doppler Ultrasound in Patients with Benign and Malignant Thyroid Nodules

目的:研究在甲状腺良恶性结节疾病鉴别诊断中彩色多普勒超声技术的临床应用效果。方法:本文采取回顾性分析研究模式对2017年2月至2018年2月期间参与诊治的40例甲状腺患者涉及的数据进行分析,均开展彩色多普勒超声检查,分析病理结果和超声诊断结果以及经彩色多普勒超声检查的临床特点,对比恶性甲状腺结节患者和良性甲状腺结节患者的阻力指数、峰值血流速度。结果:40例甲状腺患者经病理检查后有12例恶性结节、28例良性结节。术前超声诊断良性结节符合率89.28%,术前超声诊断恶性结节符合率83.33%。恶性甲状腺结节患者阻力指数、峰值血流速度等指标对比良性结节,P <0.05,统计学具有组间计算数据分析意义。恶性性结节存在更明显且丰富的血流,良性结节主要是I、II型血流,恶性结节主要是III型血流。结论:临床采取彩色多普勒超声技术诊断甲状腺良恶性结节疾病可充分展现血流特点和声像图,且彩色多普勒超声检查成为临床首选的甲状腺结节诊断方法,值得广泛应用。

Objective To study the clinical application of color Doppler ultrasound in the differential diagnosis of benign and malignant thyroid diseases. Methods A retrospective analysis of the model was used to analyze the data of 40 thyroid patients who participated in the diagnosis between February 2017 and February 2018. Color Doppler ultrasonography was performed to analyze pathological findings and ultrasound findings. The clinical characteristics of color Doppler ultrasonography were compared with the resistance index and peak blood flow velocity in patients with malignant thyroid nodules and benign thyroid nodules. Results Forty patients with thyroid disease had 12 malignant nodules and 28 benign nodules after pathological examination. The preoperative ultrasound diagnosis of benign nodules was 89.28%, and the preoperative ultrasound diagnosis of malignant nodules was 83.33%. The index of resistance index and peak blood flow velocity in patients with malignant thyroid nodules were compared with benign nodules, P<0.05. The statistical analysis showed the significance of inter-group calculation data. Malignant nodules have more obvious and abundant blood flow, benign nodules are mainly type I and type Ⅱ blood flow, malignant nodules are mainly type Ⅲ blood flow. Conclusion Color Doppler ultrasonography in the diagnosis of benign and malignant thyroid diseases can fully demonstrate the characteristics of blood flow and sonogram, and color Doppler ultrasonography has become the first choice for the diagnosis of thyroid nodules. It is worthy of wide application.
