声辐射脉冲力弹性成像在颈部淋巴瘤诊断中的应用研究

Research on application of acoustic radiation force impulse in the diagnosis about cervical iymphoma

目的:探讨声辐射脉冲力弹性成像(ARFI)在颈部淋巴瘤诊断中的应用价值。方法:对本院16例颈部淋巴瘤患者的16枚颈部淋巴结及对照组30例的30枚颈部淋巴结的ARFI资料进行回顾性研究,分析其声触诊组织成像(VTI)评分及声触诊组织量化(VTQ)测值,以评估ARFI技术在颈部淋巴瘤诊断中的应用价值。结果:16枚淋巴瘤中,75.0%(12/16)VTI评分为1分,12.5%(2/16)为2分,0%(0/16)为3分,12.5%(2/16)为4分,SWV平均值为(1.70±0.40)m·s-1。30枚健康对照组VTI评分全部(30/30)为1分,SWV平均值为(2.06±0.45)m·s-1。淋巴瘤组与对照组SWV之间差异具有统计学意义(P=0.015)。结论:ARFI在颈部淋巴瘤的诊断中可提供更多的物理信息。

Objective： To discuss the values of application of acoustic radiation force impulse（ ARFI） in diagnosis of cervical lymphoma. Methods： 16 lymphomas in 16 patients and 30 cervical lymph nodes in a control group were examined at ARFI（ VTI and VTQ）,the following characteristics of lymph nodes were evaluated： the point in VTI and SWVs in VTQ,and the data were retrospectively analyzed to evaluate the value of diagnosis in cervical lymphoma. Results： 16 lymphomas： 75%（ 12 /16） were classified as 1 point in VTI,12. 5%（ 2 /16）were 2 point,0%（ 0 /16） were 3 point,and 12. 5%（ 2 /16） were 4 point; the average of SWVs was（ 1. 70 ±0. 40） m·s^- 1. 30 cervical lymph nodes in a control group： 100%（ 30 /30） were classified as 1 point in VTI,the average of SWVs was（ 2. 06 ± 0. 45） m · s^- 1. There was statistically significant between lymphomas and the control group on average of SWVs（ P = 0. 015）. Conclusion： ARFI provides important information of hardness which conventional ultrasound cannot provide in the diagnosis on cervical lymphoma.
