摘　　要：炎症、结核、肿瘤及转移等因素均可导致颈部淋巴结的肿大,准确鉴别其良恶性对临床治疗方案有重要作用。恶性淋巴结新生血管的生成是恶性淋巴结的发生及转移的重要因素之一。动态对比增强磁共振成像(dynamic contrast enhanced magnetic resonance imaging,DCE-MRI)是一种利用小分子钆对比剂来评价微血管通透性的功能成像方法,能够通过半定量及定量参数准确地反映良恶性淋巴结通透性的差异,为临床诊疗提供更全面的诊疗信息。作者就国内外近五年,DCE-MRI半定量及定量分析在鉴别颈部淋巴结良恶性中的研究现状予以综述。Inflammation,tuberculosis,tumors,and metastasis can all lead to swelling of cervical lymph nodes.Accurate identification of benign and malignant lymph nodes plays an important role in clinical treatment.The neovascularization of malignant lymph nodes is one of the important factors for the occurrence and metastasis of malignant lymph nodes.DCE-MRI is a functional imaging method that uses a small molecule gadolinium contrast agent to evaluate microvascular permeability.It can accurately reflect the difference in permeability of benign and malignant lymph nodes through semi-quantitative and quantitative parameters,and provide more comprehensive diagnosis and treatment for clinical diagnosis and treatment.information.The author now reviews the research status of DCE-MRI semi-quantitative and quantitative analysis in the identification of benign and malignant cervical lymph nodes in the past five years at home and abroad.
