二维及频谱多普勒诊断甲状腺肿瘤的应用价值

The Diagnostic Value of Two-dimensional and Spectrum Doppler in Thyroid Neoplasm

目的:应用二维及频谱多普勒检测甲状腺肿瘤血管,并进行分析,探讨其在甲状腺肿瘤诊断和鉴别诊断中的价值,更好地为临床服务。方法:入选35例甲状腺良性肿瘤(结甲21例,腺瘤14例)和21例甲状腺癌患者术前均行二维及频谱多普勒检查,包括最高流速(Vmax),阻力指数(RI)。对良恶性肿瘤的二维图像特征及血流动力学参数差异进行分析。结果:甲状腺良恶性肿瘤的二维图像特征及血流动力学参数(Vmax、RI)存在极显著差异(P<0.01)。结论:二维及频谱多普勒对鉴别甲状腺良恶性肿瘤具有重要意义。

Objective-To detect and analysis the vascular of thyroid tumor by Two-dimensional and Spectrum Doppler Imaging , to evaluate the value of it in diagnosing and differential diagnosing thyroid tumor, to improve the accuracy of ultrasonic diagnosis in thyroid cancer. Methods： Spectrum Doppler Imaging was performed before surgery to search for blood flow signals in 35 thyroid benign masses and 21 cases of thyroid cancers, to detect the values of Vmax^RI , the differences of data between the thyroid masses and thyroid cancers were analysised. Results： There are very significant difference in the values of Two - dimensional , Vmax and RI between the beign mass and cancer （P 〈0.01）. Conclusion： Two- dimensional and Spectrum Doppler Imaging is important to distinguish the thyroid cancers from the benign ones.
