超声弹性成像评估淋巴结的研究进展

Research progress on ultrasound elastography in lymph node evaluation

淋巴结作为人体免疫系统的重要组成部分,分布于全身各个部位,各种良性和恶性疾病都可能导致淋巴结病变,而良恶性淋巴结的鉴别诊断对于预后和分期非常重要。超声弹性成像(ultrasound elastography,UE)作为一种非侵入性技术,在临床上,可以显示出淋巴结皮质和髓质的硬度和均匀性,并能发现早期局限性恶性浸润。因此,本文主要讨论超声弹性成像的原理和优缺点,以及对淋巴结肿大相关疾病的应用进展。

As an important part of the human immune system,lymph nodes are extensively distributed throughout the body.Various benign and malignant diseases may lead to lesions in lymph nodes,and the differentiation of benign and malignant lymph nodes is very important for prognosis prediction and staging.Ultrasound elastography(UE)is a non-invasive technique that can visualize the hard⁃ness and uniformity of the cortex and medulla of the lymph nodes and detect early local malignant infiltration.Therefore,this paper mainly discusses the principles and advantages and disadvantages of ultrasound elastography and the application progress on ultra⁃sound elastography in lymphadenopathy.
