超声弹性应变率与常规超声检查对甲状腺结节的鉴别诊断价值

目的：探讨超声弹性应变率与常规超声对甲状腺结节的鉴别诊断价值。方法收集行甲状腺结节超声检查及手术患者72例，共86个结节，手术前均给予常规及超声弹性应变率超声检查，手术后对结节进行病理检查。分析超声弹性应变率联合超声对甲状腺良恶性结节检查的准确性、特异性以及敏感性。结果超声弹性应变率联合常规超声的准确性93．41％，明显高于常规超声的73．67％（χ^2＝12．0，P＜0．05）。结论超声弹性应变率联合常规超声可有效鉴别甲状腺良恶性结节，提高诊断甲状腺恶性结节的准确性，有利于治疗及预后，值得临床推广。

Diagnostic value of ultrasonic elastic strain rate and conventional ultrasound for thyroid nodules

Objective To investigate the diagnostic value of ultrasonic elastic strain rate and conventional ultrasound for thyroid nodules,and to guide the clinical treatment.Methods 72 cases,a total of 86 nodules,were treated with ultrasound examination for thyroid nodules and operation were given conventional and ultrasonic elastic strain rate echocardiography before operation, after operation they had a pathological examination for tubercle.The accuracy,specificity and sensitivity of ultrasonic elastic strain rate combined with ultrasound to check the benign and malignant thyroid nodules were analyzed.Results The accuracy of ultrasonic elastic strain rate combined with con-ventional ultrasound was 93.41%,which was significantly higher than 73.67%of the conventional ultrasound （χ^2 =12.0,P〈0.05） .Conclusion Ultrasound elasticity strain rate combined with conventional ultrasound can effectively differentiate benign and malignant thyroid nodules and improve the accuracy of diagnosis of malignant thyroid nodules, which is conducive to the treatment and prognosis.
