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

Abstract

A time-intensity analysis of I 131 was carried out with a highly shielded well-collimated scintillation detector placed over the chest of normal men and women, patients and dogs. I 131 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.
