Wash-out of 133xenon from a local depot in the subcutaneous adipose tissue in the forefoot was measured continuously during 24 hours on subsequent recordings in 51 feet (normal circulation: 10, intermittent claudication: 22 and ischaemic nocturnal rest pain: 19) with a mean time interval of 26 days (range: 3-90 days). The patients were studied under two different conditions. Firstly, during the day in the erect position, awake (sitting, standing and quiet walking) and secondly, during night hours in the supine position, asleep. The coefficient of variation of nocturnal adipose tissue blood flow was calculated to 10%, and for the ratio of blood flow from day to night to 5%. The method is thus considered apt as a monitor in the treatment of peripheral vascular disease, for example, surgery and medical therapy. As predominant source of error is the formation of oedema.
在51只足（正常循环：10只，间歇性跛行：22只，缺血性夜间静息痛：19只）上进行后续记录时，连续24小时测量133氙从前足皮下脂肪组织局部贮库中的清除情况，平均时间间隔为26天（范围：3 - 90天）。在两种不同条件下对患者进行研究。首先，白天处于直立位，清醒状态（坐着、站立和安静行走）；其次，夜间处于仰卧位，睡眠状态。计算出夜间脂肪组织血流的变异系数为10%，白天与夜间血流比值的变异系数为5%。因此，该方法被认为适用于作为外周血管疾病治疗（如手术和药物治疗）中的一种监测手段。由于主要误差来源是水肿的形成。
