The Cerebral Blood Flow in Man Determined by the Use of Radioactive Krypton
Abstract
Summary.: A method for the determination of cerebral blood flow in man using the radioactive isotope krypton 85 is described. The standard deviation of cerebal blood flow was esperimentally determined to he 1.6 cc/100 g/min. Repeateil determinations of cerebral oxygen consumption at an interval of 30 minutes showed insignificant variations in 10 normal subjects and significant variations in 1 subject with slight hypertension. Repeat ect deteminations of cerebral oxygen consumption at all interval of 3 to 8 days showed significant variations in 3 out of 4 normal individuals and in none out of 5 arteriosclerotic individuals. In a group of 10 normal males and 10 normal females, mean age 38 years, the mean value for cerebral blood flow was 52 (S. D. = 8.6) cc/100 g/min., the mean value for cerebral oxygen consumption was 3.4 (S. D. = 0.58) cc/100 g/min., and the mean value for cerebral vascular resistance was 1.8 (S. D. = 0.38) mm Hg/cc/100 g/min. The method described is compared to the nitrous oxide method as described by K ety and S chmidt. The results of the two methods agree, but the krypton 85 method is more accurate, secures more normal physiological conditions during the examination. and demands less manual work.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
