目的:探讨超声造影在鉴别甲状腺良恶性结节方面的诊断价值。方法:回顾性分析2014年1月-2014年12月在台州医院行甲状腺良恶性结节超声造影检查的85例患者临床病例资料,分析超声造影技术对甲状腺良恶性结节的诊断效果。结果:85例甲状腺结节患者经病理组织检查结果显示,良性结节者52例,恶性结节者33例;结节超声造影表现为均匀低增强、高增强、等增强、无增强和斑点样增强;甲状腺良性结节表现主要为均匀性增强,恶性结节则多表现为不均匀性增强,超声造影对甲状腺良恶性结节的鉴别诊断准确率达到79.5%,尤其是对于恶性结节其诊断灵敏度为57.5%,特异度为94.0%。结论:甲状腺良恶性结节在超声造影特征方面存在差异,其中不均匀性增强在诊断甲状腺恶性结节方面具有较高临床价值。
Objective: To investigate the diagnostic value of contrast-enhanced ultrasound in differentiating benign and malignant thyroid nodules. Methods: The clinical data of 85 patients with benign and malignant thyroid nodules in Taizhou Hospital from January 2014 to December 2014 were retrospectively analyzed. The diagnostic value of contrast-enhanced ultrasound in the diagnosis of benign and malignant thyroid nodules was analyzed. Results: The pathological examination of 85 cases of thyroid nodules revealed that benign nodules were found in 52 cases and malignant nodules in 33 cases. Nodule ultrasonography showed uniform low enhancement, high enhancement, and so on, no enhancement and no spots Enhanced; the performance of benign thyroid nodules are mainly enhanced homogeneity, malignant nodules are mostly manifested as heterogeneity enhancement, ultrasound imaging of benign and malignant thyroid nodules in the differential diagnosis accuracy of 79.5%, especially for the diagnosis of malignant nodules Sensitivity was 57.5% and specificity was 94.0%. CONCLUSION: There are differences in the characteristics of ultrasound in the diagnosis of benign and malignant thyroid nodules. The enhancement of inhomogeneity has high clinical value in the diagnosis of malignant thyroid nodules.
