摘要
目的探讨良、恶性浅表肿大淋巴结声像图及多普勒血流参数变化特征,评价超声诊断技术的临床应用价值。方法98例213枚肿大淋巴结分为良、恶性两组,采用高频探头观察肿大淋巴结的形态、大小、内部回声及血流动力学指标。并结合病理,分析不同病因浅表肿大淋巴结的超声特征。结果恶性淋巴结横径、形态更接近圆形,多融合,其周边型血流明显高于良性淋巴结(P<0.05),良性肿大淋巴结血流分支细少,走行规律,呈低阻力;恶性呈高阻力,为不规则扭曲、紊乱血流。结论超声在浅表肿大淋巴结定性诊断中可为临床提供更多诊断信息,为影像学首选诊断方法。
Objective To investigate differences between benign and malignant superficial enlarged lymph nodes with two-dimensional and Doppler ultrasonography, and to evaluate its clinical application. Methods Two hundred and thirteen enlarged lymph nodes of ninety-eight patients were divided into benign and malignant groups. The size, morphology, echo and blood flow dynamic parameters of the lymph nodes were observed, and the characteristics of superficial enlarged lymph nodes resulting from different pathogenesis was analysed. Results Compared with benign group, a larger cross section, rounder shape was observed in malignant group. The distribution of benign group showed small branch blood flow, regular formation and low-resistant spectrum, and the distribution of malignant group showed malposition, deformation disorder and high-resistant spectrum. Conclusion Ultrasonography is a preferable method in diagnosis of superficial enlarged lymph nodes.
