甲状腺恶性肿瘤超声诊断的价值及误诊分析

Diagnostic value of ultrasonography in the diagnosis of thyroid malignant tumor and analysis of misdiagnosis

目的:分析甲状腺恶性肿瘤超声诊断的价值及误诊情况。方法:选取就诊的50例患者为研究对象,采用回顾分析法,均给予超声检查,观察其诊断价值,以及误诊率。结果:本组50例患者,超声检查诊断符合率为76.0%(38/50),误诊12例,其中微小癌误诊率最高为66.7%,与其他相比,差异有显著统计学意义。超声检查显像多为实性结构低回声与混合性回声,低回声病灶常见砂砾样钙化,彩色血流信号丰富,平均峰值血流速度(32.5±5.6)cm/s,平均阻力指数为0.73±0.06。结论:甲状腺恶性肿瘤患者首选诊断方法为超声检查,临床实践中应综合分析患者临床资料,以此保证诊断准确率。

Objective To analyze the value of ultrasound diagnosis and misdiagnosis of thyroid malignant tumor. Method 50 patients in our hospital were selected as the research object,using the retrospective analysis method,Ultrasonic examination were given,to observe the diagnostic value,as well as the rate of misdiagnosis. Results In this group of 50 cases,the diagnostic accuracy of ultrasound was 76. 0%（38 /50）,12 cases were misdiagnosed,and the rate of misdiagnosis was 66. 7%,and the difference was significant. Ultrasound imaging was mostly the real structure of low echo and mixed echo,low echo lesions common gravel like calcification,colorful blood flow signals,mean peak blood flow velocity（ 32. 5 ± 5. 6） cm / s,the average resistance index was0. 73 ± 0. 06. Conclusion The preferred diagnostic method for patients with thyroid malignant tumor is ultrasound,In clinical practice,we should analyze the clinical data of patients in order to ensure the accuracy of diagnosis.
