Measurement of the spatial distribution of the clearance rate of xenon-133 from the kidney after its injection into the renal artery for estimating intrarenal blood flow can easily be combined with selective X-ray angiography as a routine method. Using a gamma camera as detection equipment anand applying a special computer analysis technique, 'functional images' can be obtained, by which the spatial distribution of the blood flow in the kidney is quantitatively mapped. Experiments with a rather heterogenous group of 12 patients suggest that in at least one type of renal pathology the xenon-133 flow study is more indicative for clinical evaluation than the X-ray angiography
将放射性氙-133注入肾动脉后，通过测量其从肾脏清除率的空间分布来估计肾内血流量，这一方法能够轻松地与选择性X射线血管造影术相结合，成为一种常规手段。利用伽马相机作为检测设备，并应用一种特殊的计算机分析技术，即可获得“功能图像”，借此对肾脏内血流的空间分布进行定量测绘。针对12名患者组成的异质性群体开展的实验表明，在至少一种肾脏病理类型中，氙-133血流研究在临床评估方面比X射线血管造影更具指示性。
