超声成像联合声触诊定性弹性成像在鉴别甲状腺良恶性结节中应用研究

目的:探讨超声成像联合声触诊定性弹性成像在鉴别甲状腺良恶性结节中应用价值.方法:以2012年5月~2013年12月我院收治的经手术病理证实的82例甲状腺良恶性结节患者(共82个甲状腺结节)为研究对象,依据入院顺序均分为联合组及单一组,2组患者均行超声成像检查,联合组另联合声触诊定性弹性成像检查,参照病理组织检查结果,对比2组诊断鉴别甲状腺良恶性结节的临床应用价值.结果:82例患者(82个结节),良性结节52个,恶性结节30个,联合组诊断甲状腺良恶性结节的与病理诊断结果符合率较单一组显著高,且联合组诊断的敏感性、特异性、准确性、阳性预测值、阴性预测值均较对照组显著高.结论:声触诊定性弹性成像在鉴别甲状腺良恶性结节中应用价值较超声成像技术显著高,两者成像技术的联合应用可提高甲状腺良恶性结节诊断的敏感性、特异性、准确性,推荐临床广泛应用.

Study on application of ultrasonic imaging combined with acoustic palpation qualitative elastography in the differential diagnosis of benign and malignant thyroid nodules

Objective To explore the application value of ultrasonic imaging combined with acoustic palpation qualitative elastography in the differential diagnosis of benign and malignant thyroid nodules. Methods Eighty-two patients with benign and malignant thyroid nodules(a total of 82 thyroid nodules)confirmed by surgery and pathology who were admitted to our hos-pital between May 2012 and December 2013 were selected as study subjects. According to the order of admission, they were divided into combined group and single group. Both groups underwent ultrasound imaging examination. The combined group was additionally examined by ultrasonic imaging qualitative elastography. Referring to the results of pathological examination, the clinical application value was compared between the two methods in the differential diagnosis of benign and malignant thy-roid nodules. Results In 82 cases(82 nodules), 52 nodules were benign nodules and 30 nodules were malignant nodules. The coincidence rate with the results of pathological diagnosis of diagnosis of benign and malignant thyroid nodules in the combined group was higher than that in the single group. The sensitivity, specificity, accuracy, positive predictive value and negative pre-dictive value of the combined group were significantly higher than those of the control group. Conclusion The application value of ultrasonic imaging in the differential diagnosis of benign and malignant thyroid nodules is significantly higher than that of ul-trasonic imaging. The combined use of the two methods can improve the accuracy, sensitivity and specificity of the diagnosis of benign and malignant thyroid nodules. It is recommended in clinical application.
