目的:总结实时超声造影检查中不同性质甲状腺实性结节的特征性表现情况。方法:对100例经手术病理验证的甲状腺结节患者(110个结节)进行实时超声造影诊断,观察记录超声造影时相对增强时间以及良恶性结节内部增强特征与边缘增强情况。结果:增强早期,良性结节所占比例多高于恶性结节,且多表现为高增强与均匀整体增强以及边缘增强,而恶性结节多延迟增强,且表现为低增强与局部不增强以及边缘不规则增强或无边缘结构,差异显著,p<0.05。结论:在甲状腺实性结节检查诊断中,应用超声造影技术进行定性鉴别具有较高的诊断价值。
Objective: To summarize the characteristic manifestations of solid thyroid nodules with different properties in real-time contrast-enhanced ultrasound. Methods: 100 cases of thyroid nodules (110 nodules) proved by surgery and pathology were diagnosed by real-time contrast-enhanced ultrasound (CEUS). The relative enhancement time of ultrasound contrast and internal enhancement and edge enhancement of benign and malignant nodules were observed and recorded. Results: The proportion of early stage and benign nodules was higher than that of malignant nodules, and most of them showed high enhancement, uniform overall enhancement and edge enhancement, while the malignant nodules showed more delayed enhancement with low enhancement and local non-enhancement and Edge irregularity enhancement or edgeless structure, the difference was significant, p <0.05. Conclusion: In the diagnosis of thyroid solid nodules, the application of contrast-enhanced ultrasound in the differential diagnosis has high diagnostic value.
