JCEM:超声弹性成像可用于甲状腺结节鉴别诊断

2013-09-29 desperado-c DXY

超声(US)弹性成像(USE)最近被报道为是一种敏感、无创的识别甲状腺癌的方法。然而,这种技术的准确性受到同一操作员每次操作之间变异性和不同操作员之间变异性、结节的一些US特征和合并自身免疫性甲状腺疾病(ATD)的限制。为了评价与其他超声特征相比,USE在甲状腺结节鉴别诊断中的准确性,评估合并ATD时USE的可行性,确定最高诊断性能的应变指数(SI)切点,来自意大利帕维亚大学Luca Chiova

超声(US)弹性成像(USE)最近被报道为是一种敏感、无创的识别甲状腺癌的方法。然而,这种技术的准确性受到同一操作员每次操作之间变异性和不同操作员之间变异性、结节的一些US特征和合并自身免疫性甲状腺疾病(ATD)的限制。为了评价与其他超声特征相比,USE在甲状腺结节鉴别诊断中的准确性,评估合并ATD时USE的可行性,确定最高诊断性能的应变指数(SI)切点,来自意大利帕维亚大学Luca Chiovato教授及其团队进行了一项研究,该研究发现超声(US)弹性成像(USE)在甲状腺结节鉴别诊断中有高敏感性、特异性和阴性预测值。 该研究结果在线发表在2013年9月24日的The Journal of Clinical Endocrinology & Metabolism杂志上。【原文下载

该研究中,在528例连续患者中评估共计661个甲状腺结节。所有结节进行细针穿刺抽吸细胞学(FNAC)检查和USE评估。SI计算方法为结节的应变率除以周围正常组织中最柔软部位的应变率。

该研究结果表明,ATD阳性、ATD阴性和ATD未知患者中THY4和THY5结节的SI值中位数显著高于THY2结节。在一个筛查组中(379个FNAC结果)通过ROC曲线分析恶性结节的SI切点估计在2.905,并且随后在一个复制组中(252个FNAC结果)进行检测。所有病例中,SI≥2.905提示这个结节为恶性的概率显著增加。与恶性结节的常规US特征相比,这个SI切点有最大的AUC、敏感性和NPV。

该研究发现,在合并和不合并ATD的甲状腺恶性肿瘤的诊断中,弹性成像SI有高敏感性、特异性和阴性预测值。
