摘　　要：目的探讨剪切波弹性成像(SWE)对甲状腺乳头状癌(PTC)颈部淋巴结转移的预测价值。方法选取2017年1月—2020年2月安徽省宣城市人民医院收治的52例PTC患者,行常规超声及SWE检查,分析SWE参数与颈部淋巴结转移的相关性,比较常规超声及SWE的预测价值。结果多元回归分析结果显示:无淋巴门、淋巴结血流分布为混乱型/边缘型及Emean、Emax、Emin增大是PTC颈侧区及中央区淋巴结转移的影响因素,淋巴结纵横比>1/2是中央区淋巴结转移的影响因素(P<0.05)。SWE预测PTC颈部淋巴结转移的敏感性、特异性、准确性、阳性预测值、阴性预测值均高于常规超声;曲线下面积0.94大于常规超声。结论SWE诊断PTC颈部淋巴结转移具有较高的敏感性和特异性,可在一定程度上预测PTC是否出现颈部淋巴结转移。Objective To investigate the predictive value of shear wave elastography(SWE)in cervical lymph node metastasis of papillary thyroid carcinoma(PTC).Methods A total of 52 patients with PTC admitted to the People’s Hospital of Xuancheng City from January 2017 to February 2020 were selected for routine ultrasound and SWE examinations the correlation between SWE parameters and cervical lymph node metastasis were analyzed,and the predictive value of conventional ultrasound and SWE were compared.Results The results of multiple regression analysis showed that no lymphatic hilum,disorganized/borderlined blood flow distribution of lymph nodes,and increased Emean,Emax,and Emin were the influencing factors for lymph node metastasis in the cervical and central areas of PTC.Lymph node aspect ratio>1/2 was the influencing factor of central lymph node metastasis(P<0.05).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of SWE in predicting PTC cervical lymph node metastasis were higher than conventional ultrasound.Area under the curve was 0.94,which was greater than conventional ultrasound.Conclusion SWE has a high sensitivity and specificity in the diagnosis of PTC cervical lymph node metastasis.It can predict whether PTC cervical lymph node metastasis can occur to a certain extent.
