Cardiac Output of Men and Dogs Measured by in vivo Analysis of Iodinated (I 131 ) Human Serum Albumin

Abstract
A time-intensity analysis of I131 was carried out with a highly shielded well-collimated scintillation detector placed over the chest of normal men and women, patients and dogs. I131 human serum albumin solution was injected intravenously. The curves thus obtained when analyzed for cardiac output gave values not significantly different from simultaneously obtained direct Fick values.
