超声在甲状腺良恶性病变中的诊断价值分析

Diagnostic Value of Ultrasound in Benign and Malignant Thyroid Lesions

目的探讨超声在诊断甲状腺良恶性病变中的应用价值。方法选择2018年1月~2019年6月我院收治的92例甲状腺结节患者为研究对象,根据疾病的良恶性将其分为良性组54例和恶性组38例,均行甲状腺超声检查,比较两组超声特征,探讨超声诊断价值。结果恶性组甲状腺结节纵横比≥1、边缘不规整、结节极低回声、微钙化、边界模糊发生率,Ⅲ级血流信号发生率,血流频谱收缩期峰速、舒张末期血流速度值均高于良性组,两组比较差异均有统计学意义(均P<0.05);超声检查甲状腺结节良恶性病变敏感度为89.74%、特异度为94.34%。结论彩色多普勒超声检查甲状腺良恶性病变有较高应用价值,两者超声图像有明显差异,应用价值高,值得推广。

Objective To eexplore the value of ultrasound in diagnosis benign and malignant thyroid lesions. Methods 92 patients with thyroid nodules admitted to our hospital from January 2018 to June 2019 were selected as the research objects. According to the benign and malignant of the disease, they were divided into 54 cases in the benign group and 38 cases in the malignant group. All of them were underwent thyroid ultrasound examination. The ultrasound characteristics of the two groups were compared and explore the value of diagnosis. Results In the malignant group, the aspect ratio of thyroid nodules ≥1, irregular edges, very hypoechoic nodules, microcalcification, incidence of blurring of borders and grade Ⅲ blood flow signals, blood flow spectrum systolic peak velocity, end-diastolic blood flow velocity values were all higher than that in the benign group, and the difference between the two groups was statistically significant(all P<0.05);the sensitivity of ultrasound for benign and malignant thyroid nodules was 89.74% and the specificity was 94.34%. Conclusion Color doppler ultrasound has high application value in detecting benign and malignant thyroid lesions. There are obvious differences between the two ultrasound images. It has a high application value and is worthy of promotion.
