Error in blood flow measurements in chronic experiments by radioactive microspheres, specified per organ. Fluorescent and radioactive microspheres were injected simultaneously in rabbits 2 months before the animals were killed. No indications were found for the disappearance of fluorescent labels from the spheres. Radioactive microsphere blood flow values are expressed as a fraction of the fluorescent microsphere (FM) blood flow (mean of two simultaneously injected labels). Note log scale on vertical axis. Each data point is the average of three to five tissue samples from organs of one to two animals. (Figure reproduced from Ref. [45] with permission from the American Physiological Society.)
