Prospective comparison of B-mode-, plain and signal-enhanced colour Doppler ultrasound to evaluate new criteria for assessment of the tumour status of enlarged cervical lymph nodes.
Colour Doppler sonography was performed before and after application of d-galactose in 35 patients with suspected lymph node metastases of the neck. Sonomorphology was analysed qualitatively, maximal flow rate, pulsatility index and resistance index were determined quantitatively.
Signal enhanced Doppler revealed a typical vessel morphology of the lymph nodes facilitating differential diagnosis. In 23%, vascularisation of the lymph nodes was only visible after application of the signal-enhancing agent (benign: 44%, malignant: 5%). The measurement of flow velocity and the calculation of RI and PI did not lead to a reliable differentiation between malignant and benign lymph nodes whereas B-mode sonography yielded highly valid results.
The application of d-galactose facilitates differentiation between malignant and benign lymph nodes.
对B超、普通彩色多普勒超声及信号增强彩色多普勒超声进行前瞻性比较，以评估用于评估颈部肿大淋巴结肿瘤状态的新标准。
对35例疑似颈部淋巴结转移的患者在应用d-半乳糖前后进行彩色多普勒超声检查。对超声形态进行定性分析，定量测定最大流速、搏动指数和阻力指数。
信号增强多普勒显示了淋巴结典型的血管形态，有助于鉴别诊断。23%的病例中，仅在应用信号增强剂后才可见淋巴结血管化（良性：44%，恶性：5%）。流速测量以及RI和PI的计算无法可靠地区分恶性和良性淋巴结，而B超检查结果高度有效。
应用d-半乳糖有助于鉴别恶性和良性淋巴结。
