目的:分析结节性甲状腺肿、甲状腺腺瘤的超声鉴别诊断效果.方法:纳入80例甲状腺疾病确诊患者,以二维超声对其病理类型展开病理分析,结节性甲状腺肿和甲状腺腺瘤的超声声像图特征.结果:(1)本组研究中80例甲状腺疾病患者,结节性甲状腺肿者超声诊断符合率87.50％,甲状腺腺瘤者超声诊断符合率93.75％,误诊3例结节性甲状腺肿,两组患者的诊断符合率无显著差异.(2)甲状腺疾病声像图特征表现显示:结节边缘低回声晕环和周围甲状腺组织差异显著.(3)甲状腺疾病血流声像图表现显示:结节性甲状腺肿肿块内部及周边血流匮乏,“,”Objective: analyze the effect of ultrasound in differential diagnosis of nodular goiter and thyroid adenoma. Methods: 80 patients with thyroid diseases were included, pathological analysis of their pathological types by two-dimensional ultrasound, nodular goiter and thyroid adenoma Ultrasound image characteristics. Results: (1) In this group of 80 patients with thyroid disease, the coincidence rate of ultrasound diagnosis of nodular goiter was 87.50％, the coincidence rate of ultrasound diagnosis of thyroid adenoma was 93.75％, and 3 cases of nodular goiter were misdiagnosed, two groups There was no significant difference in the patient\'\'s diagnosis coincidence rate. (2) The sonographic features of thyroid diseases show that there is a significant difference between the hypoechoic halo at the edge of the nodule and the surrounding thyroid tissue. (3) The blood flow sonogram of thyroid disease shows that the blood flow inside and around the nodular goiter is lacking, while the blood supply of adenoma is abundant. Conclusion: The pathological similarity between nodular thyroid and thyroid adenoma is relatively high. When diagnosing thyroid disease, clinicians should make accurate clinical diagnosis and differential diagnosis based on the characteristics of ultrasound images and clinical symptoms.
