Gallium citrate Ga 67 (67Ga) scans were performed in 50 consecutive lymphoma patients who underwent routine staging. The overall accuracy of 67Ga scans was greater than 80% for all nodal sites except the spleen (68%). Sensitivity was greater than 88% in the neck and mediastinum, 67% in the abdomen-pelvis, and 33% for the spleen. Specificity was greater than 85% for all nodal sites except for the mediastinum (67%). The accuracy of pedal lymphangiograms was 75%, sensitivity 87%, and specificity 68%. Gallium 67 scans complemented the lymphogram in the abdomen-pelvis but, due to limited sensitivity and high number of equivocal studies (16%), did not replace it. Infraclavicular, pectoral, and mediastinal lesions were detected by 67Ga scans when missed by other means. In 20% to 25% of patients, 67Ga scans provided information not afforded by other diagnostic studies and are therefore considered an important staging procedure for lymphoma patients.
对50例接受常规分期的淋巴瘤患者进行了枸橼酸镓Ga 67（67Ga）扫描。除脾脏（68%）外，67Ga扫描对所有淋巴结部位的总体准确率均高于80%。颈部和纵隔的敏感性高于88%，腹盆腔为67%，脾脏为33%。除纵隔（67%）外，所有淋巴结部位的特异性均高于85%。足部淋巴管造影的准确率为75%，敏感性为87%，特异性为68%。67Ga扫描在腹盆腔补充了淋巴管造影，但由于敏感性有限且有大量可疑研究（16%），无法取代淋巴管造影。当其他方法漏诊时，67Ga扫描可检测到锁骨下、胸肌和纵隔病变。在20%至25%的患者中，67Ga扫描提供了其他诊断研究无法提供的信息，因此被认为是淋巴瘤患者重要的分期检查方法。
