超声检查对结节性甲状腺肿与甲状腺腺瘤患者的诊断效果

Diagnostic effect of ultrasonographic diagnosis in nodular goiter and thyroid adenoma

目的分析结节性甲状腺肿与甲状腺腺瘤患者的超声声像图特征。方法对我院收治的经病理学确诊为结节性甲状腺肿的70例患者(腺肿组)和确诊为甲状腺腺瘤的55例患者(腺瘤组)的临床资料进行回顾性分析,比较两组患者的超声声像图特点。结果两组患者的甲状腺大小、结节形状、包膜和晕环比例比较,差异显著(P<0.05)。腺瘤组患者结节内部血流与结节周边血流的血流丰富比例均高于腺肿组(P<0.05)。腺肿组患者的结节周边峰值流速及阻力指数均明显小于腺瘤组(P<0.05)。结论依据二维超声图信息,结合彩色多普勒得到的血流参数,临床可通过综合分析对甲状腺腺瘤和结节性甲状腺肿作出较准确的判断。

Objective To analyze the ultrasonographic features of patients with nodular goiter and thyroid adenoma.Methods The clinical data of 70 patients diagnosed as nodular goiter by pathology（goiter group） and 55 patients diagnosed as thyroid adenoma（adenoma group） in our hospital were retrospectively analyzed. The ultrasonographic features of the two groups were compared. Results The differences in thyroid size, nodular shape, nodule capsule and halo between the two groups were significant（P〈0.05）. The proportions of internal blood flow of nodule and blood flow around the nodule in the adenoma group were higher than those in the goiter group（P〈0.05）. The peak velocity around the nodules and resistance index in the goiter group were significantly smaller than those in the adenoma group（P〈0.05）. Conclusion Based on the information of two-dimensional ultrasonic graph and combined with the blood flow parameters obtained by color Doppler,more accurate judgment can be made in thyroid adenoma and nodular goiter clinically.
