高频彩超在浅表淋巴结定性诊断中的临床应用

Clinical application of high-frequency color doppler ultrasonography in qualitative diagnosis for superficial lymph nodes

目的:探讨高频彩超在定性诊断浅表淋巴结病变中的临床应用价值。方法:应用彩色多普勒超声观察经病理或临床证实的80例炎性、97例恶性患者的浅表淋巴结长短径、淋巴结门髓质部厚度、彩色血流特征。结果:炎性淋巴结纵径变异大,淋巴结门髓质部增厚,以中央血流为主;恶性淋巴结横径变异大,淋巴结门髓质部变薄或消失,以周边型血流为主。结论:高频彩超对浅表淋巴结定性诊断具有重要临床意义。

Objective：To access the clinical application of high-frequency color doppler uhrasonography in qualitative diagnosis for enlarged superficial lymph nodes. Methods： A retrospective analysis of enlarged superficial lymph nodes was made in eighty cases with inflammatory and ninty-seven cases with maglignant lesions, of which forty-two were lymphoma and fifty-five were metastasis. All cases were confirmed by pathological examination and clinical approach. The vertical size, horizontal size, medullary thickness of lymphatic door and charactercise of blood flow in enlarged superficial lymph nodes were examined by high-frequency color doppler uhrasonography. Results：In inflammation lymph nodes, vertical size varied much, mainly with central blood flow. The medullary of lymphatic door became thicker in inflammation enlarged lymph nodes. In maglignant enlarged lymph nodes, horizontal size varied much, mainly with peripheral blood flow. The medullary of lymphatic door became narrow or disappear. Conclusion： High-frequency color doppler uhrasonography had definite value in qualitative diagnosis for enlarged superficial lymph nodes.
