目的探讨超声弹性应变率与常规超声鉴别甲状腺结节的应用价值。方法 166例经术前、术后检查确诊的甲状腺结节患者,手术证实共204个甲状腺结节。分别给予其超声弹性应变率检查和常规超声检查。对比分析常规超声、超声弹性应变率及联合诊断的诊断准确率。结果良性、恶性甲状腺结节弹性应变率比较,差异有统计学意义(P<0.05);常规超声、超声弹性应变率、联合诊断鉴别甲状腺结节的准确率分别为74.0%、75.0%、88.2%,联合诊断的准确率明显高于常规超声(P<0.05),但常规超声与超声弹性应变率结果比较,差异无统计学意义(P>0.05)。结论常规超声与超声弹性应变率在临床鉴别诊断甲状腺结节中的应用价值相当,而两者联合,能提升诊断准确率,为临床治疗提供必要的参考依据。
Objective To investigate the application of ultrasonic elastic strain rate and conventional ultrasound in differentiating thyroid nodules. Methods A total of 204 thyroid nodules were confirmed by operation in 166 cases of thyroid nodules confirmed by preoperative and postoperative examinations. Respectively given its ultrasonic elastic strain rate examination and conventional ultrasound. Contrast analysis of conventional ultrasound, ultrasonic elastic strain rate and diagnostic accuracy of combined diagnosis. Results The rates of elastic strain in benign and malignant thyroid nodules were significantly different (P <0.05). The accuracy rates of routine ultrasound and ultrasonic elastic strain rate in diagnosis of thyroid nodules were 74.0%, 75.0% and 88.2% respectively, (P <0.05). However, there was no significant difference between conventional ultrasound and ultrasonic elastic strain rate (P> 0.05). Conclusion Conventional ultrasound and ultrasonic elastic strain rate in the clinical diagnosis of thyroid nodules in the application of similar values, and the combination of the two can improve the diagnostic accuracy, provide the necessary reference for clinical treatment.
