【摘要】 目的探讨超声弹性应变率比值在桥本甲状腺炎合并甲状腺良恶性结节鉴别诊断中的应用价值。方法分析36例50个经穿刺活检或手术后病理证实的桥本甲状腺炎(HT)合并甲状腺结节的超声弹性图像,计算病灶同侧胸锁乳突肌与病灶的应变率比值(strain rate),以5.03为界点判断结节的良恶性。结果 50个HT合并甲状腺结节中,恶性12个,良性38个,恶性结节应变率比的均值为7.83±4.95,良性结节应变率比的均值为2.89±1.50,两者的差别有统计学意义(P<0.05)。以5.03为诊断的最佳界点,则弹性成像应变率比值判断桥本甲状腺炎合并结节良恶性的敏感性、特异性和准确性分别为75.0%、92.1%和84.0%。结论超声弹性应变率比值在HT合并甲状腺良恶性结节的鉴别诊断中有较高的诊断价值。更多还原

【Abstract】 Objective To evaluate the clinical value of strain ratio using real-time elastosonography in differential diagnosis of benign and malignant thyroid nodules with Hashimoto thyroiditis.Methods Elasticity imaging was used to examine 36 Hashimoto thyroiditis patients with 50 nodules.The stain ratio was obtained through sternocleidomastoid and lesion.The cut off point of stain ratio was determined as 5.03,which is used to differential diagnosis of benign and malignant nodules.Results There were 12 malignant nodules and 38 benign ones in 36 Hashimoto thyroiditis with thyroid nodules.The mean of elastics stain ratio of benign and malignant was 2.89±1.50 and 7.83±4.95(P< 0.05).The cut off point of stain ratio was determined as 5.03,and the sensitivity,specificity,veracity was 75.0%, 92.1%and 84.0%respectively in differential diagnosis of benign and malignant nodules with Hashimoto thyroiditis. Conclusions The stain ratio has high value in the differential diagnosis of malignant and benign nodules with Hashimoto thyroiditis.更多还原
