目的:研究彩色多普勒超声对诊断甲状腺良恶性肿瘤的鉴别分析。方法:选取某院甲状腺良、恶性肿瘤病人共100例作为调查研究对象。对所有病人进行彩色多普勒超声检查,检查内容包括甲状腺结节的血流信号分布、钙化、回声等指标,比较超声与病理诊断结果并分析符合率。结果:86%的彩色多普勒超声诊断结果与甲状腺肿瘤病理诊断结果一致,超声诊断结果显示,血流信号分布差异较为突出,不同性质的甲状腺肿瘤的血流信号分布差异有统计学意义(P<0.05);并且钙化、低回声、RI≥0.65对甲状腺癌的诊断准确性、特异性及敏感性均大于60%。结论:彩色多普勒超声能提高甲状腺肿瘤的诊断准确率,并且在临床上取得的效果较为满意,是简单可靠的辅助诊断方法。另外,确诊甲状腺癌可通过观察其结节的钙化情况及血流。
Objective: To study the differential diagnosis of benign and malignant thyroid tumors by color Doppler ultrasonography. Methods: A hospital selected thyroid benign and malignant tumor a total of 100 cases as the research object. Color Doppler echocardiography was performed on all patients, including blood flow distribution, calcification, echo and other indicators of thyroid nodules. Ultrasound and pathological diagnosis results were compared and the coincidence rate was analyzed. Results: 86% of the color Doppler ultrasound diagnostic results and thyroid tumor pathological diagnosis results, ultrasound diagnosis showed that the distribution of blood flow signal is more prominent, different types of thyroid tumor blood flow signal distribution was statistically significant (P <0.05). And the diagnostic accuracy, specificity and sensitivity of calcification, hypoechoic, RI≥0.65 in thyroid cancer were all more than 60%. Conclusion: Color Doppler ultrasound can improve the diagnostic accuracy of thyroid tumors, and the results obtained in clinical are more satisfactory. It is a simple and reliable diagnostic assistant method. In addition, the diagnosis of thyroid cancer by observing the calcification of the nodules and blood flow.
