实时超声弹性成像对常规恶性甲状腺结节的鉴别探讨

Study on Identification of Ultrasonic Elastography in Normal and Malignant Thyroid Nodules

目的探讨实时超声弹性成像对常规恶心甲状腺结节的鉴别诊断价值。方法选取我院2013年10月至2014年10月收治的常规恶性甲状腺结节患者50例,先行常规超声检查,观察结节形态、回声以及钙化等情况,再在纵切面进行实时弹性成像,最后将超声诊断结果与病理结果进行对比分析。结果实时弹性成像结果显示,50例患者中Ⅰ、Ⅱ级为0,Ⅲ级患者8例,Ⅳ级患者11例,Ⅴ级患者39例。其中,将高度恶性预测指标为实时弹性成像分级Ⅳ、Ⅴ级,则其特异度为84.37%,灵敏度为92.14%,准确率为91.21%,显然实时超声弹性成像明显高于单纯超声检查。结论实时超声弹性成像对常规恶性甲状腺结节来说具有重要的鉴别诊断价值,值得在临床上推广应用。

Objective To investigate the differential diagnosis of conventional real-time ultrasound elastography nausea thyroid nodules.Methods 50 cases in our hospital routine malignant thyroid nodules in patients from October 2013 to October 2014 were treated in advance of routine ultrasound examination, observation nodular shape, echo and calcification, etc., and then in the longitudinal section in real-time elastography, Finally, the ultrasound diagnostic results were compared with pathological results. ResultsReal-time elastography results showed that 50 patients Ⅰ, Ⅱ level is 0, Ⅲ grade 8 patients, Ⅳ grade 11 patients, Ⅴ grade 39 patients. Among them, the high-grade real-time elastography predictor grade Ⅳ, Ⅴ grade, its specificity was 84.37%, a sensitivity of 92.14%, 91.21% accuracy rate, real-time ultrasound elastography apparently significantly higher than ultrasound.ConclusionThe real-time ultrasound elastography has important differential diagnosis of malignant thyroid nodules routine, it is worth in clinical application.
