Eighteen patients who underwent whole-body scintigraphy 24 and 48 hours after intravenous injection of 67Ga-citrate were evaluated retrospectively. At 24 hours, 7 of the 16 normal patients (44%) and both abnormal patients demonstrated significant pulmonary uptake. However, by 48 hours, only 2 normal patients (12%) remained positive, while both abnormal patients continued to show significant pulmonary activity. The authors conclude that 48-hour 67Ga images offer improved specificity and uncompromised sensitivty in patients with diffuse pulmonary disease.
对18例在静脉注射枸橼酸镓67后24小时和48小时接受全身闪烁扫描的患者进行了回顾性评估。在24小时时，16例正常患者中的7例（44%）以及2例异常患者均显示肺部有明显摄取。然而，到48小时时，仅有2例正常患者（12%）仍为阳性，而2例异常患者肺部仍有明显放射性。作者得出结论，对于弥漫性肺部疾病患者，48小时的镓67图像具有更高的特异性且不影响敏感性。
