目的:探讨在甲状腺良恶性结节诊断中超声检查的应用价值。方法:选取2014/6-2015/12间我院收治的200例甲状腺结节患者,其中良性结节118例(350个结节),设为良性组,恶性结节82例(140个结节),设为恶性组,采用彩色多普勒超声诊断仪观察患者的结节数量、性质、血流特征等。结果:超声诊断良性及恶性结节的符合率分别为89.0%和59.8%,两组的结节数目无显著差异(P>0.05),在结节是否钙化、回声类型、后方回声、内部结构、周边是否有晕环、形态是否规整、边界是否模糊、纵径/横径方面的比较均有显著差异,良性组血流分布为0级或1级者占61.4%,高于恶性组(30.0%),2级或3级者占38.6%,低于恶性组(70.0%),PSV与RI均低于恶性组,P<0.05,差异具有统计学意义。结论:采用超声诊断甲状腺结节的符合率较高,根据图像特点可以从多个方面鉴别良性与恶性结节,具有重要的应用价值。
Objective: To investigate the value of ultrasonography in the diagnosis of benign and malignant thyroid nodules. Methods: A total of 200 thyroid nodules were enrolled in our hospital from 2014 / 6-2015 / 12, including 118 benign nodules (350 nodules), which were set as benign and 82 malignant nodules (140 nodules ), As a malignant group, the use of color Doppler ultrasound diagnosis of patients with nodules the number, nature, blood flow characteristics. Results: The coincidence rates of ultrasound diagnosis of benign and malignant nodules were 89.0% and 59.8% respectively. No significant difference was found in the number of nodules between the two groups (P> 0.05). Whether nodules were calcified, echo type, posterior echo, internal structure, There were significant differences in the longitudinal and transverse diameters between the halo and the periphery in the benign group (61.4%), higher than the malignant group (30.0%), ), Grade 2 or 3 accounted for 38.6%, lower than the malignant group (70.0%), PSV and RI were lower than the malignant group, P <0.05, the difference was statistically significant. Conclusion: Ultrasound diagnosis of thyroid nodules with a high coincidence rate, according to the characteristics of the image can be identified from multiple aspects of benign and malignant nodules, has important application value.
