Thermodilution cardiac output determinations and multigated equilibrium blood‐pool scintigraphy were performed in ten healthy chacma baboons ( Papio ursinus ). The correlation was moderately good between both the radionuclide and thermodilution stroke volume (r=0.58, SEE = 3 ml; SV th = 0.78SV r +15.6 ml) as well as the cardiac output (r=0.72, SEE=0.2 liter/min; CO th =0.56 Co r +2.1 liter/min). The attenuation depth d r as determined by radionuclide techniques was found to correlate well with the radiologically determined values d x (r=0.8, SEE=0.4 cm; d x =0.87d r +0.72 cm) which validated the depth values used in the calculations.
