Videodensitometry has made it possible to determine not only total but also regional blood flow within the kidney. In animal experiments good agreement was found between the measurements by videodensitometry and isotope technique, taking vein samples, using 125I-labelled Angiografin. The blood flow in 21 human kidney has been determined by both videodensitometry and Xe wash-out method. The correlation was fairly good.
视频密度测定法不仅能够测定肾脏的总血流量，还能测定局部血流量。在动物实验中，通过视频密度测定法和同位素技术（采集静脉血样，使用125I标记的泛影葡胺）进行的测量结果吻合良好。通过视频密度测定法和氙洗脱法测定了21例人肾的血流量。两者的相关性相当好。
