摘要: |
目的? 探讨经淋巴管超声造影(LCEUS)及超声剪切波弹性成像(SWE)对甲状腺癌(TC)中央区转移淋巴结的评价。方法? 选取2020年2月~2023年2月在本院确诊的70例TC患者,根据有无淋巴结转移,分为转移组(n=30)和无转移组(n=40)。转移组和无转移组均接受LCEUS和SWE检查,比较LCEUS参数(灌注顺序、灌注模式、到达时间、达峰时间、峰值强度)、SWE参数[杨氏模量最大值(Emax)、最小值(Emin)、平均值(Emean)]。采用绘制受试者工作特征(ROC)分析 LCEUS和SWE对TC中央区转移淋巴结诊断效能的ROC曲线特征。结果? 转移组和无转移组关于灌注顺序、灌注模式、到达时间、达峰时间、峰值强度等LCEUS参数的差异有统计学意义(P<0.05);转移组的SWE参数Emax、Emin和Emean高于无转移组(P<0.05)。ROC分析可见,到达时间、达峰时间、峰值强度、Emax、Emin、Emean及联合检测诊断TC中央区转移淋巴结的AUC分别为0.582、0.698、0.771、0.861、0.660、0.757、0.764,敏感度分别为70.00%、66.70%、76.70%、86.70%、76.70%、78.00%、90.00%,特异度分别为40.00%、62.50%、67.50%、85.00%、60.00%、62.50%、57.50%。结论? LCEUS联合SWE诊断TC中央区转移淋巴结具有较高的敏感度,具有较高的临床价值。 |

Abstract: |
Objective To explore the evaluation value of contrast-enhanced ultrasound through lymphatic vessel (LCEUS) and ultrasonic shear wave elastography (SWE) in central compartment lymph node metastasis of thyroid carcinoma (TC). Methods A total of 70 patients with TC confirmed in the hospital were enrolled between February 2020 and February 2023. According to presence or absence of lymph node metastasis, they were divided into metastasis group (n=30) and non-metastasis group (n=40). All underwent LCEUS and SWE. LCEUS parameters (perfusion order, perfusion mode, arrival time, time to peak, peak intensity) and SWE parameters [the maximum Young modulus (Emax), the minimum Young modulus (Emin), mean Young modulus (Emean)] were compared. The diagnostic efficiency of LCEUS and SWE for central compartment lymph node metastasis of TC was analyzed by receiver operating characteristic (ROC) curves. Results There were significant differences in LCEUS parameters (perfusion order, perfusion mode, arrival time, time to peak, peak intensity) between metastasis group and non-metastasis group (P<0.05). SWE parameters (Emax, Emin, Emean) in metastasis group were higher than those in non-metastasis group (P<0.05). ROC curves analysis showed that AUC, sensitivity and specificity of arrival time, time to peak, peak intensity, Emax, Emin, Emean and combined detection in the diagnosis of central compartment lymph node metastasis were (0.582, 0.698, 0.771, 0.861, 0.660, 0.757, 0.764), (70.00%, 66.70%, 76.70%, 86.70%, 76.70%, 78.00%, 90.00%) and (40.00%, 62.50%, 67.50%, 85.00%, 60.00%, 62.50%, 57.50%), respectively. Conclusion LCEUS combined with SWE has high sensitivity and clinical value in the diagnosis of central compartment lymph node metastasis of TC. |
