Cervical lymph node metastasis is an important determinant of cancer stage and the selection of an appropriate treatment plan for patients with head and neck cancer. Therefore, metastatic cervical lymph nodes should be effectively differentiated from lymphoma, tuberculous lymphadenitis, and other benign lymphadenopathies. The aim of this work is to describe the performance of Doppler ultrasound and superb microvascular imaging (SMI) in evaluating blood flow information of cervical lymph nodes. In addition, the features of flow imaging in metastatic lymph nodes, lymphoma, and tuberculous lymphadenitis were described. Compared with Doppler ultrasound, SMI, the latest blood flow imaging technology, could detect more blood flow signals because the sensitivity, specificity, and accuracy of SMI in the diagnosis of cervical lymph node disease were higher. This article summarizes the value of Doppler ultrasound and SMI in evaluating cervical lymph node diseases and focuses on the diagnostic performance of SMI.
颈部淋巴结转移是头颈部癌症患者癌症分期和选择合适治疗方案的重要决定因素。因此，转移性颈部淋巴结应与淋巴瘤、结核性淋巴结炎和其他良性淋巴结病有效区分。本研究旨在描述多普勒超声和超微血流成像（SMI）在评估颈部淋巴结血流信息方面的性能。此外，还描述了转移性淋巴结、淋巴瘤和结核性淋巴结炎的血流成像特征。与多普勒超声相比，作为最新的血流成像技术，SMI 可以检测到更多的血流信号，因为 SMI 在诊断颈部淋巴结疾病方面的敏感性、特异性和准确性更高。本文总结了多普勒超声和 SMI 在评估颈部淋巴结疾病中的价值，并重点介绍了 SMI 的诊断性能。
