常规超声联合超声弹性成像在诊断甲状腺占位性病变中的应用价值

目的：为了进一步提高临床对甲状腺占位性病变的诊断率，分析和探讨常规超声配合超声弹性成像应用的必要性。方法：随机选取我院两腺外科门诊就诊的139例患者，共162个甲状腺占位性病变，均采用常规超声和超声弹性成像检查，且对照患者术后病理结果，分析应用超声弹性成像诊断甲状腺占位性病变的可行性。结果：常规超声检测结果，敏感度为84．48％，特异度为82．69％，准确率为83．33％；超声弹性成像（UE）检测结果其敏感度为91．38％，特异度为89．42％，准确率为89．02％。在鉴别甲状腺占位良恶性方面，常规超声与超声弹性图诊断的准确率相比较，差异有统计学意义（P〈0．05）。结论：临床上在分辨甲状腺占位病变良恶性时，超声弹性成像具有一定的诊断价值，可以配合常规超声进行诊断，从而提高诊断准确率。

Application value of conventional ultrasound combined with ultrasound elastography in diagnosis of thyroid lesions

Objective. To further improve the clinical diagnostic rate of thyroid lesions, and to ana- lyze and discuss the necessity of using conventional ultrasound combined with ultrasound elastography. Methods. Randomly chose 139 cases who were scheduled for ultrasound and ultrasound elastography exam- ination from June 2012 to June 2013, of which 162 patients had thyroid lesions, and to analyze feasibility of application of ultrasound elastography in diagnosis of thyroid lesions by comparing examination results with pathologic results. Results. Conventional ultrasonic testing results showed sensitivity was 84.48%, the specificity was 82.69%, the accuracy was 83.33%; ultrasound elastography （UE） test results showed a sensitivity of 91. 38% and specificity of 89.42%, the accuracy was 89.02%. The difference in identifica- tion of benign thyroid lesions from malignant ones was significant between the two methods （P〈0.05）.Conclusions. Uhrasound elastography shows diagnostic wdue in differentiating benign from malignant thy roid lesions, ultrasound elastography has some diagnostic value, and it can be used combining with con ventional ultrasound for diagnosis.
