摘要
目的 :探讨彩色多普勒超声定性诊断浅表肿大淋巴结的价值。材料和方法 :应用彩色多普勒超声观测经病理 /临床证实的 15例炎性、2 0例淋巴瘤 (9例 )或转移癌 (11例 )患者的浅表淋巴结门髓质部厚度 /淋巴结厚度、血流分布及动力学参数 ,与 2 5例正常受检者相应指标比较。结果 :淋巴结门髓质部厚度与淋巴结厚度比值 ,炎性组 >正常组 >恶性组 ;恶性组血流频谱呈高速高阻型 ,炎性组、正常组呈相对低速低阻型。结论 :彩色多普勒超声对浅表淋巴结定性诊断具有较高价值。
Purpose: To assess the value of color Doppler ultrasonography in diagnosing the superficial lymphadenopathy. Materials and Methods: Twenty-five normal volunteers, 15 patients with chronic adenitis, 9 lymphoma and 11 metastasis were included in the study. The ratio of lymph node hilus thickness to lymph node thickness, blood flow changes in the lymph node arteries were observed and measured respectively. All the indices were statistically analyzed. Results: Among the normal, begin and malignant groups, the ratio of lymph node hilus thickness to lymph node thickness was different, with the maximum in chronic adenitis and the minimum in malignant. The highest PSV and RI was found in malignant group. Conclusion: Color Doppler ultrasonography is of value in diagnosing superficial lymphadenopathy.
