【摘要】：目的探讨三维能量多普勒超声(3DPDUS)在诊断颈部转移性淋巴结中的应用价值。方法对116个颈部肿大淋巴结行3DPDUS检查,观察三维血流分型,计算血管血流指数(VFI),绘制ROC曲线并与病理结果对照分析。结果行3D PDUS检查并经病理证实:转移性淋巴结67个,主要表现为周边型血流(53.73%)和混合型血流(32.84%),VFI为4.781±3.000;炎性反应性增生49个,主要表现为中央型血流(73.47%)和无血流型(18.37%),VFI为1.429±1.012;上述差异均有统计学意义(P0.05)。当选取VFI=2.652为最佳诊断界点,ROC曲线下面积(AUC)为0.907、灵敏度为79.1%、特异度为87.8%。结论三维能量多普勒血流分型和定量参数VFI对诊断颈部转移性淋巴结有较高的应用价值。
[Abstract]:Objective to evaluate the value of 3D-PDUS in the diagnosis of metastatic cervical lymph nodes. Methods 116 enlarged cervical lymph nodes were examined by 3DPDUS, and three dimensional blood flow classification was observed. Vascular blood flow index (VFI) was calculated, ROC curve was drawn and compared with pathological results. Results 67 metastatic lymph nodes were examined by 3D PDUS and confirmed by pathology. The VFI was 4.781 卤3.000, the inflammatory reactive hyperplasia was 49, and the VFI was 4.781 卤3.000 in the peripheral blood flow (53.73) and the mixed blood flow (32.84). VFI was 1.429 卤1.012, the difference was statistically significant (P 0.05). When VFI=2.652 was chosen as the best diagnostic threshold, the area under the ROC curve was 0.907, the sensitivity was 79.1, and the specificity was 87.80.Conclusion Three-dimensional energy Doppler imaging is a good method for the diagnosis of ROC, and its sensitivity is 79.1, and the specificity is 87.80.Conclusion when VFI=2.652 is selected as the best diagnostic threshold, the area under the ROC curve is 0.907, the sensitivity is 79.1, and the specificity is 87.8. Blood flow classification and quantitative parameter VFI are valuable in the diagnosis of cervical metastatic lymph nodes.
