摘要
目的探讨超声弹性成像应变率值（strain ratio，SR）对桥本甲状腺炎（Hashimoto，s thyroiditis，HT）的诊断价值。方法收集116例经临床确诊的HT患者，根据甲状腺功能分为甲状腺功能亢进组、甲状腺功能正常组、亚临床甲状腺功能减低组、临床甲状腺功能减低组，并以50例甲状腺功能正常者作为对照组，测量甲状腺与同侧颈部胸锁乳突肌的SR，分别统计各组间SR的差异，并分析其与血清促甲状腺激素（thyroid stimulating hormone，TSH）的相关性。结果SR甲状腺功能亢进组〈对照组〈甲状腺功能正常组〈亚临床甲状腺功能减低组〈临床甲状腺功能减低组，HT的SR与血清TSH呈显著正相关（r＝0．605，P＝0．000）。结论超声弹性成像SR法有助于评价HT的病程进展情况。
Objective To investigate the value of strain ratio （SR） in the diagnosis of Hashimoto＇s thyroiditis. Methods 116 patients who had been diagnosed clinically as Hashimoto＇s thyroiditis were enrolled in the study. Those patients were classified into four groups： the hyperthyroidism group, the euthyroidism group, the subclinical hypothyroidism group, and the clinical hypothyroidism group. 50 volunteers with normal thyroid functions were enrolled as a control group. SR of the thyroid and sternocleidomastoid muscle of same side was calculated. The correlation coefficient between the elasiticity SR and the serum thyroid stimulating hormone （TSH） was evaluated and their differences in the diagnosis of Hashimoto＇s thyroiditis were compared. Results The Spearman＇s correlation coefficient between the SR and the serum TSH was 0. 605 ,which was significant （ P = 0. 000）. The SR increased in an ascending order among the group with hyperthyroidism, the control group, the group with euthyroidism, the group with subclinical hypothyroidism, and the group with clinical hypothyroidism. Conclusions Elastography SR is valuable way for evaluating the progression of Hashimoto＇s thyroiditis.
