彩色多普勒超声与超声弹性成像对甲状腺肿瘤的诊断效果对比分析

Comparative analysis of the diagnostic effects on thyroid tumors by color Doppler ultrasonography or ultrasonic elastography

目的探讨彩色多普勒超声与超声弹性成像对甲状腺肿瘤的诊断效果。方法选取2015年1月~2016年3月在我院甲状腺科就诊的170例患者作为观察对象,随机分为实验组与参照组,各85例。参照组采用彩色多普勒超声检查,实验组采用超声弹性成像检查,将两组的超声检查结果与后期病理学结果进行对比分析。结果实验组的病理诊断结果为结节性甲状腺肿22例,滤泡状腺癌8例,髓样癌6例,乳头状腺癌17例,甲状腺腺瘤32例。参照组的病理诊断结果为结节性甲状腺肿22例,滤泡状腺癌10例,髓样癌8例,乳头状腺癌14例,甲状腺腺瘤31例。实验组的超声诊断符合率为97.65%,显著高于参照组的71.76%,差异有统计学意义(P<0.05);实验组超声诊断的特异度为91.25%,敏感度为93.78%,显著高于参照组的69.81%和72.73%,差异有统计学意义(P<0.05)。结论超声弹性成像检查在甲状腺肿瘤患者诊断中的准确度高于彩色多普勒超声检查。

Objective To explore the diagnostic effects of color Doppler ultrasonography or ultrasonic elastography on thyroid tumors.Methods From January 2015 to March 2016,170 patients in the department of thyroid of our hospital were selected as the observation objects.They were randomly divided into the experimental group and the control group,85 cases in each group.In the control group,color Doppler ultrasonography was used,while in the experimental group,ultrasonic elastography was adopted.The ultrasonographic findings in the two groups were comparatively analyzed with those by pathological results in later.Results The pathological diagnosis in the experimental group was nodular goiter in22 cases,follicular thyroid cancer in 8 cases,medullary carcinoma in 6 cases,papillary adenocarcinoma in 17 cases,and thyroid adenoma in 32 cases.The number of nodular goiter,follicular thyroid cancer,medullary carcinoma,papillary adenocarcinoma,and thyroid adenoma was 22,10,8,14,31 cases in the control group accordingly.The diagnostic accordance rate of ultrasound was 97.65% in the experimental group,which was much higher than that in the control group accounting for 71.76%,with statistical difference（P〈0.05）.In the experimental group,the specificity and sensitivity of ultrasound diagnosis were 91.25% and 93.78%,which was much higher than that in the control group accounting for 69.81% and72.73%,respectively,which were displayed statistical differences（P〈0.05）.Conclusion The accuracy of ultrasonic elastography is higher than that of color Doppler ultrasonography in the diagnosis of patients with thyroid tumors.
