目的应用超声弹性成像对比淋巴瘤组淋巴结与转移组淋巴结的弹性成像特征,以探讨弹性成像在淋巴瘤组淋巴结诊断中的临床价值。方法回顾性分析淋巴瘤组67例淋巴结与转移组58例淋巴结的弹性图像特点,包括弹性图像的定性及应变率比值特点。结果淋巴瘤组淋巴结与转移组淋巴结与周围组织的弹性应变率比值平均值分别为1.29±0.39、1.70±0.55(P=0.000)。弹性应变率比值法(≤1.5)诊断淋巴瘤性淋巴结灵敏度可以达到82.09%。结论超声弹性成像在淋巴瘤性淋巴结和转移性淋巴结的鉴别诊断中提供一定的诊断信息。 Objective To compare the characteristics of elastography between lymph nodes and lymph nodes in lymphoma by ultrasound elastography to explore the clinical value of elastography in the diagnosis of lymph nodes in lymphoma. Methods The characteristics of elastic images of lymph nodes in 67 lymph nodes and metastases of lymphoma group were analyzed retrospectively, including the qualitative and strain rate characteristics of elastic images. Results The average ratios of elastic strain rates between lymph nodes and surrounding tissues in lymph node group and metastasis group were 1.29 ± 0.39,1.70 ± 0.55 (P = 0.000), respectively. The ratio of elastic strain rate (≤1.5) can be used to diagnose lymphatic lymph nodes with a sensitivity of 82.09%. Conclusion Ultrasound elastography provides some diagnostic information in the differential diagnosis between lymphatic lymph nodes and metastatic lymph nodes.
