Perfusion of enlarged lymph nodes by colour-coded sonography was studied prospectively in 105 benign and 115 malignant lymph nodes. The diagnosis was confirmed histologically in 158 and clinically in 62. Spectral analysis in the benign lymph nodes provided normal values for pulsatility and resistance indices. A pulsatility index greater than = 1.8, or a resistance greater than = 0.9 indicate lymph node metastases with positive prediction of 93% and specificity of 97%. In addition, subjective, semiquantitative classification of lymph node perfusion in relation to the surrounding fat or connective tissue improves the diagnosis of lymph node metastases and of malignant lymphomas.
对105个良性淋巴结和115个恶性淋巴结进行了前瞻性彩色编码超声灌注研究。158个通过组织学确诊，62个通过临床确诊。对良性淋巴结的频谱分析提供了搏动性和阻力指数的正常值。搏动指数大于或等于1.8，或阻力大于或等于0.9提示淋巴结转移，阳性预测值为93%，特异性为97%。此外，根据与周围脂肪或结缔组织的关系对淋巴结灌注进行主观、半定量分类，可提高对淋巴结转移和恶性淋巴瘤的诊断。
