浅淋巴结病变的超声诊断

目的：探讨超声诊断对不同病因所致浅淋巴结肿大的临床应用价值。方法：应用超声诊断仪并高频探头，检测72例91枚淋巴结不同病变的回声表现及血流动力学特点。结果：淋巴结不同病变的回声有异，血流动力学表现不一，其中收缩期最大值流速（Vmax)及阻力指数（RI）：非何杰金淋巴瘤＞何杰金淋巴瘤＞淋巴结转移癌＞急性淋巴结炎＞慢性淋巴结炎（均有统计学意义）。结论：超声诊断不同病因所致浅淋巴结肿大有一定的临床价值，其血流动力学表现对良、恶性病变的分辨更有实际意义。

Ultrasonic Diagnosis of Superficial Pathologically Enlarged Lymphnodes

Objective:To evaluate the significance of ultrasound in diagnosis of the superficial pathologicially enlarged lymphnode.Methods:A prospective study was undertaken with high frequency 2DUS and CDFI in 91 enlarged peripheral lymphnode of 72 patients with different diseases. The sonographic features and vascular peak systolic velocity(Vmax),end diastolic velocity(Vmin), resistivity index(RI) of the each enlarged node were investigated.Results:The different etiological nodes was shown a variable sonographic appearance. The Doppler indices (Vmax and RI) was shown non Hodgkin's lymphoma>Hodgkin's lymphoma > lymphnode metastases> acute lymphadenitis>chronic lymphadenitis ( P <0 05).Conclusions: There is different echo pattern in the 91 nodes and significant difference in the Doppler indices between benign and malignant nodes, suggesting that further differentiation of malignant node may be possible. The ultrasound possesses higher chinical value.
