摘要
目的探讨超声微细血流显像在鉴别诊断颈部淋巴结良恶性中的应用价值。方法选择2019年6月至2022年3月超声检查发现颈部异常淋巴结肿大患者114例,分别采用常规二维灰阶超声(US)联合彩色多普勒血流成像(CDFI)、能量多普勒成像(PDI)、微血流成像(MFI)三种超声检查技术对淋巴结疾病进行诊断,比较不同超声检查技术诊断颈部肿大淋巴结良恶性的准确率。结果114例患者检查了114个颈部肿大淋巴结,手术病理证实62例患者为良性淋巴结,38例患者为转移性淋巴结,14例患者为淋巴瘤性淋巴结;US联合CDFI、PDI、MFI三种超声检查技术鉴别诊断颈部肿大淋巴结的准确率分别为80.70%、77.19%及90.35%,以US联合MFI的诊断准确率最高(P<0.05)。结论超声微细血流显像可以更敏感显示淋巴结内部血管走形的改变以及异常微小新生血管血流信号的出现,可以更全面显示淋巴结的血流分布,从而提高淋巴结良恶性诊断的准确率。
Objective To investigate the application value of Ultrasound Micro-flow Imaging(MFI)in the differential diagnosis of benign and malignant cervical lymph nodes.Methods One hundred and fourteen patients with cervical lymphadenectasis in our hospital from June 2019 to March 2022 were enrolled in our study,and were took examine with conventional grayscale ultrasound(US)combined with Colour Doppler Flowing Imaging(CDFI),Power Doppler Imaging(PDI),and MFI for differential diagnosis respectively.The diagnostic accuracies of cervical enlarged lymph nodes were analysed.Results One hundred and fourteen enlarged cervical lymph nodes were examined in 114 patients,of which 62 were benign lymph nodes,38 were metastatic lymph nodes,and 14 were lymphoma lymph nodes.The diagnostic accuracies of US combined CDFI,PDI,and MFI were 80.70%,77.19%and 90.35%,respectively,while the diagnostic accuracy of US combined MFI was the highest(both P<0.05).Conclusion MFI can more sensitively display the changes of blood vessels in the lymph nodes and the appearance of abnormal micro-vascular blood flow signals,which can more comprehensively display the blood flow distribution of lymph nodes,thereby improving the sensitivity and accuracy of lymph node diagnosis.
