| 中文摘要: |
| 许多疾病表现为浅表淋巴结肿大,临床需要有效的方法鉴别淋巴结的良、恶性。应用高频超声能够观察淋巴结的结构和血流分布,并进行血流动力学分析,近年来出现的超声造影能够进一步观察淋巴结的血流灌注情况,恶性淋巴结呈现特征性的血流灌注特征,以此鉴别淋巴结性质准确性高。超声应作为鉴别浅表淋巴结病变的首选影像学检查方法,对疾病的早期发现与诊断有重要意义。本文 综述了超声对良、恶性浅表淋巴结病变的鉴别要点。 |
| 英文摘要: |
| Superficial lymph node enlargement is the manifestation of many diseases. Lymph node characterization is an important clinical issue. High-frequency gray-scale ultrasound, color Doppler flow imaging and power Doppler imaging have shown to supply useful information for differentiating malignant from benign superficial lymph nodes. Recently the advance in contrast-enhanced agents enable to evaluate the perfusion characteristics of lymph nodes, different lymph node diseases present characteristic enhancement pattern, and it has a high degree of diagnostic accuracy on the basis of the perfusion characteristics. Ultrasound should be the first-line diagnostic method for differential diagnosis of superficial lymph node diseases. This review focuses on the sonographic criteria for differential diagnosis of benign and malignant lymph nodes. |
