Eleven patients suspected of having tumor involving para-aortic lymph nodes were studied with the Varian 6 second whole body CT scanner. All patients had a pedal lymphangiogram; six were abnormal. In three of these six, CT provided clinically important information on the extent of disease which was not detectable by other radiographic studies. CT scanning improved on lymphangiographic interpretation when large bulky nodes were only partially filled and when whole chains of nodes failed to fill. In both situations, the enlarged paraaortic nodes were well delineated on CT. The internal architecture and morphological abnormalities of small well filled nodes were better portrayed by lymphangiography. In the four cases in which lymphangiograms were normal and the one case in which the lymphangiogram showed reactive hyperplasia, the CT scans were normal.
对11名疑似患有累及腹主动脉旁淋巴结肿瘤的患者使用瓦里安6秒全身CT扫描仪进行了研究。所有患者均进行了足部淋巴管造影；其中6例异常。在这6例中的3例中，CT提供了关于疾病范围的重要临床信息，而这些信息通过其他影像学检查无法检测到。当大的肿大淋巴结仅部分显影以及整条淋巴结链未显影时，CT扫描在淋巴管造影解读方面更具优势。在这两种情况下，肿大的腹主动脉旁淋巴结在CT上都能清晰显示。淋巴管造影能更好地描绘充盈良好的小淋巴结的内部结构和形态异常。在淋巴管造影正常的4例以及淋巴管造影显示反应性增生的1例中，CT扫描结果均正常。
