目的探究“萤火虫”成像技术联合剪切波弹性成像在诊断甲状腺结节中的应用价值。方法选择2015年4月—2016年6月在本院收治患有甲状腺结节的患者120例,共195个甲状腺结节,以术后病理活检作为诊断金标准,应用“萤火虫”成像技术、剪切波弹性成像以及两种技术联合诊断,比较两种技术诊断甲状腺结节的灵敏度、特异度以及正确率。计数资料采用χ2检验,P<0.05为差异有统计学意义。结果 “萤火虫”成像技术诊断甲状腺结节的灵敏度、特异度、正确率分别为81.93%、82.14%、82.05%,剪切波弹性成像分别为83.13%、80.36%、81.54%,“萤火虫”成像技术联合剪切波弹性成像分别为93.98%、93.75%、93.85%,两种检查手段联合诊断的灵敏度、特异度、正确率均显著高于单纯一种方法,对比差异有统计学意义(P<0.05)。结论 “萤火虫”成像技术联合剪切波弹性成像诊断甲状腺结节具有较高的灵敏度和正确率,可以有效地提高临床诊断水平,对甲状腺结节良、恶性判断有着较高的临床价值。
Objective To explore the application value of “Firefly” imaging combined with shear wave elastography in the diagnosis of thyroid nodules. Methods From April 2015 to June 2016, 120 patients with thyroid nodules in our hospital were enrolled. A total of 195 thyroid nodules were obtained. Postoperative pathological biopsy was used as the gold standard for diagnosis. The “Firefly” imaging technique , Shear wave elastography and the combination of the two techniques to compare the sensitivity, specificity and accuracy of the two techniques in the diagnosis of thyroid nodules. Count data using χ2 test, P <0.05 for the difference was statistically significant. Results The sensitivity, specificity and correct rates of thyroid nodules diagnosed by “Firefly” imaging were 81.93%, 82.14%, 82.05%, 83.13%, 80.36%, 81.54% “Imaging technique combined shear wave elastography were 93.98%, 93.75%, 93.85%, respectively, the sensitivity, specificity and accuracy of the combination of the two methods were significantly higher than the simple method, the difference was statistically significant (P <0.05). Conclusion ”Firefly" imaging combined with shear-wave elastography in the diagnosis of thyroid nodules has high sensitivity and accuracy, which can effectively improve the level of clinical diagnosis, and has a high clinical value in the diagnosis of benign and malignant thyroid nodules.
