目的探讨超声弹性成像及精细彩色血流显像(fine flow)技术在颈部淋巴结良恶性鉴别诊断中的价值.方法对87例肿大淋巴结分别进行常规超声、Fine flow及弹性成像,与病理或临床随访结果对照,采用Kappa一致性检验和ROC曲线分析3种超声检查结果的准确性.结果常规超声的一致性较差(Kappa=0.153,P =0.078),Fine flow的一致性中等(Kappa=0.526,P＜0.01),而弹性成像的一致性较好(Kappa=0.741,P＜0.01).常规超声的ROC曲线下面积为0.568(P=0.241),准确率较差;Fineflow的ROC曲线下面积0.787(P＜0.01);弹性成像ROC曲线下面积为0.899(P＜0.01),准确率较高.结论超声弹性成像对于颈部淋巴结良恶性的鉴别诊断具有较高的应用价值.

Objective To explore the diagnostic value of ultrasonic elastography and fine flow imaging in differential diagnosis of cervical lymph nodes.Methods Totally 87 lymph nodes were examined with ultrasonic elastography,fine flow and conventional ultrasonography.The results were confirmed with postoperative pathology or fine-needle biopsy as well as follow-up.Using consistency check of Kappa and ROC curve to analyse the accuracy of three types of ultrasonic examination.Results Taking the results of postoperative pathology or fine-needle biopsy as well as follow-up as golden standards,the Kappa value of conventional ultrasonography was poor (Kappa =0.153,P =0.078),fine flow was moderate (Kappa =0.526,P ＜0.01) and ultrasonic elastography was better (Kappa =0.741,P ＜0.01).The area under ROC of ultrasonic elastography,fine flow and conventional ultrasonography was 0.899 (P ＜0.01),0.787 (P ＜0.01) and 0.568 (P =0.241),respectively.Conclusions Ultrasonic elastography is more valuable to differentiate malignant from benign lymph nodes.
