超声弹性成像与常规超声诊断甲状腺结节的效果比较

目的:比较超声弹性成像与常规超声对甲状腺结节的临床诊断价值,以期为该病的临床诊疗提供指导依据。方法:回顾性分析本院2020年2月~2020年11月收治的经病理检查确诊的甲状腺结节病患者68例临床资料,包括良性结节52例,恶性结节16例,采用荷兰飞利浦公司EPIQ5型彩色多普勒超声诊断仪进行检查,所有患者均接受常规超声和超声弹性成像检查,以病理结果为标准,比较常规超声和超声弹性成像诊断结果与病理结果的一致性,诊断准确率、灵敏度及特异度。结果:超声弹性成像检查诊断出良性结节46例、恶性结节9例;常规超声检查诊断出良性结节44例、恶性结节7例;与病理结果的一致性均较好(Kappa=0.701,0.687);超声弹性成像诊断准确率为80.88%(55/68)、敏感度为56.25%(9/16)、特异度为86.79%(46/53);常规超声诊断准确率为75.00%(51/68)、敏感度为43.75%(7/16)、特异度为83.02%(44/53);两组检查方法的诊断准确率、敏感度及特异度比较差异无统计学意义(P>0.05)。结论:超声弹性成像与常规超声均是诊断甲状腺结节的有效手段,临床可根据实际情况进行合理选择。

Comparison of Ultrasound Elastography and Conventional Ultrasound in the Diagnosis of Thyroid Nodules

Objective:To compare the clinical diagnostic value of ultrasound elastography and conventional ultrasound in thyroid nodules,in order to provide guidance for clinical diagnosis and treatment of this disease.Methods:Clinical data of 68 patients with thyroid sarcoidosis diagnosed by pathological examination in our hospital from February 2020 to November 2020 were retrospectively analyzed,including 52 cases of benign nodules and 16 cases of malignant nodules.EPIQ5 color Doppler ultrasonography from Philips Netherlands was used for examination.All patients received conventional ultrasound and ultrasound elastography.The consistency,diagnostic accuracy,sensitivity and specificity of conventional ultrasound and ultrasound elastography were compared with pathological results.Results:46 cases of benign nodules and 9 cases of malignant nodules were diagnosed by ultrasound elastography.Conventional ultrasonography diagnosed benign nodules in 44 cases and malignant nodules in 7 cases.The consistency with pathological results was good(Kappa=0.701,0.687).The diagnostic accuracy,sensitivity and specificity of ultrasound elastography were 80.88%(55/68),56.25%(9/16)and 86.79%(46/53).The accuracy,sensitivity and specificity of conventional ultrasound diagnosis were 75.00%(51/68),43.75%(7/16)and 83.02%(44/53).There were no significant differences in diagnostic accuracy,sensitivity and specificity between the two groups(P>0.05).Conclusion:Ultrasound elastography and conventional ultrasound are both effective methods for diagnosing thyroid nodules,which can be rationally selected according to the actual situation.
