Abstract：
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.
摘要：
颈淋巴结转移是决定头颈部肿瘤分期和选择合适治疗方案的重要因素。因此,转移性颈淋巴结应与淋巴瘤有效区分，结核性淋巴结炎,和其他良性淋巴结病。这项工作的目的是描述多普勒超声和出色的微血管成像（SMI）在评估颈部淋巴结血流信息中的表现。此外,转移性淋巴结的血流成像特征，淋巴瘤并描述了结核性淋巴结炎。与多普勒超声相比，SMI,最新的血流成像技术,可以检测到更多的血流信号，因为灵敏度，特异性，SMI诊断颈部淋巴结病变的准确率较高。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。
