| 目的 探讨应用实时剪切波弹性成像(SWE)技术鉴别诊断淋巴瘤和转移淋巴结的临床价值。方法 对可疑结内淋巴瘤患者于活检前行常规超声及剪切波弹性成像检查，获取图像和指标。以病理结果为标准，得到淋巴瘤组25例，转移组30例。分析两组淋巴结各指标差异。通过ROC曲线评价用弹性模量均值鉴别两种恶性淋巴结的诊断效能。结果 二维超声指标中仅淋巴门消失与否存在统计学差异。两组间在取样框色彩充填是否完整及弹性模量值间存在显著差异。转移组淋巴结的弹性模量均值（30.01±13.26）kPa高于淋巴瘤组（14.43±2.46）kPa。淋巴结弹性模量均值鉴别淋巴瘤和转移淋巴结的灵敏度为83.3％。结论 SWE获取的颈部淋巴结弹性图像及弹性模量值可以为鉴别恶性淋巴结性质提供诊断依据。 |

| Abstract: |
| Abstact:Objective To evaluate the clinical value of real shear wave elastography (SWE) in the differential diagnosis of lymphoma and metastatic lymph nodes. Methods Get images and indicators from suspected lymphoma involved lymph nodes before biopsy by routine ultrasound and SWE .Use pathological results as standerd ,get 25 cases of lymphoma and 30 cases of metastatic lymph nodes .Compare indicators of two groups.Evaluate the diagnostic performance of differential diagnosis lymphoma and metastatic lymph nodes with the mean of Young’s modulus by ROC curve.Results The significant distinguishing features for conventional ultrasound was the absent of echogenic hilum only.For SWE,if the sampling frame filled with colors completed and Young’s modulus demonstrated significant differences between groups.The mean of Young’s modulus of metastasis lymph nodes (30.01±13.26)kpa was higher than that of lymphoma involved lymph nodes (14.43±2.46)kpa.The mean of Young’s modulus of lymph nodes could achive 83.3% sensitivity in diagnosing metastatic lymphadenopathy.Conclutions The elastography images and Young’s modulus of cervical lymph nodes by SWE are helpful for distinguish the nature of malignat lymph nodes. |
