目的分析颈部增大淋巴结超声造影灌注模式及时间-强度曲线(TIC)参数特点,探讨超声造影对颈部淋巴结的诊断价值。方法回顾性分析97例颈部增大淋巴结超声造影灌注模式及TIC参数特点,比较转移性淋巴结、淋巴瘤及反应增生性淋巴结超声造影表现及TIC参数。结果超声造影灌注模式中造影剂动脉期灌注方式(向心性强化/离心性强化)、是否均匀增强及是否合并无增强区在转移性淋巴结与反应增生性淋巴结之间、转移性淋巴结与淋巴瘤两组间比较差异均具有统计学意义(P<0.05)。转移性淋巴结峰值强度(PI)与淋巴瘤及反应增生性淋巴结差异均有统计学意义(P<0.05),TIC参数k在转移性淋巴结与淋巴瘤两组间比较差异具统计学意义(P<0.05)。结论超声造影增强模式及时间-强度曲线参数特点有助于提供诊断信息,对颈部增大淋巴结诊断及鉴别有一定价值。
Objective To analyze the contrast-enhanced perfusion mode and time-intensity curve (TIC) parameters of enlarged lymph nodes in the neck to evaluate the value of contrast-enhanced ultrasound in the diagnosis of cervical lymph nodes. Methods A retrospective analysis of 97 cases of enlarged neck lymph node contrast-enhanced perfusion mode and TIC parameters characteristics of metastatic lymph nodes, lymph nodes and reactive hyperplasia of lymph node contrast-enhanced imaging and TIC parameters. Results Contrast medium arterial phase perfusion mode (concentric enhancement / centrifugal enhancement), uniform enhancement and whether there was no enhancement area in the contrast-enhanced perfusion mode between metastatic lymph nodes and reactive hyperplastic lymph nodes, metastatic lymph nodes and lymphoma The differences between the groups were statistically significant (P <0.05). There were significant differences between the peak value of metastatic lymph node (PI) and lymphoma and lymph node response (P <0.05), the difference of TIC parameter k between metastatic lymph node and lymphoma was statistically significant (P < 0.05). Conclusions Contrast enhancement mode and the characteristic of time-intensity curve parameters are helpful to provide diagnostic information and have some value in the diagnosis and identification of enlarged lymph nodes in the neck.
