Gallium imaging offers many practical advantages over indium-111-labeled leukocyte imaging, and calculating quantitative ratios in addition to performing the routine bone-gallium images allows accurate and easy evaluation of patients with suspected osteomyelitis. To add objectivity and improve the accuracy and confidence in diagnosis of osteomyelitis, quantitative comparison of abnormalities seen on bone scans and gallium scans was performed. One hundred and ten adult patients with 126 sites of suspected osteomyelitis were evaluated and categorized by gallium-to-bone ratios, gallium-to-background ratios, and spatial incongruency of gallium and bone activity. Combined evaluation using these criteria gave a 70% sensitivity and 93% specificity for the diagnosis of osteomyelitis.
与铟 - 111标记的白细胞成像相比，镓成像具有许多实际优势，除了进行常规的骨镓显像外，计算定量比值还能准确、简便地评估疑似骨髓炎的患者。为了增加诊断的客观性并提高骨髓炎诊断的准确性和可信度，对骨扫描和镓扫描中发现的异常进行了定量比较。对110例有126处疑似骨髓炎部位的成年患者进行了评估，并根据镓与骨的比值、镓与本底的比值以及镓和骨活性的空间不一致性进行了分类。使用这些标准进行综合评估，对骨髓炎诊断的敏感性为70%，特异性为93%。
