摘　　要：目的 探讨超声造影到达时间参数成像对颈部反应性增生淋巴结与转移性淋巴结的鉴别诊断价值。方法 选取经病理证实的反应性增生淋巴结42枚,转移性淋巴结73枚,使用超声造影到达时间参数成像对比分析两组淋巴结造影剂灌注模式及中心-外周到达时间差(△T)。结果 转移组多呈混合型灌注,反应性增生组多呈离心型灌注,两组间差异有统计学意义(P<0.05);转移组△T大于反应性增生组(P<0.05)。ROC曲线分析:△T>3.61 s为诊断转移性淋巴结最佳截断值。结论 超声造影到达时间参数成像可为颈部反应性增生淋巴结与转移性淋巴结的鉴别诊断提供更客观的参考依据。Objective To explore the value of ATPI in the different of cervical reactive lymph nodes and cervical metastatic lymph nodes. Methods A total of 42 reactive hyperplastic lymph nodes and 73 metastatic lymph nodes confirmed by pathology were selected.ATPI was used to compare and analyze the contrast agent perfusion mode and central-peripheral arrival time difference(△T)between the two groups. Results Mixed perfusion was found in the metastatic group and centrifugal perfusion was found in the reactive hyperplasia group, and the difference between the two groups was statistically significant(P<0.05).The △T of metastatic group was longer than that of reactive hyperplasia group(P<0.05).ROC curve analysis showed that △T>3.61 s was the best cut-off value for the diagnosis of metastatic lymph nodes. Conclusions ATPI can provide more objective reference for the differential diagnosis of cervical reactive hyperplasia lymph nodes and metastatic lymph nodes.
