In experiments on open chest dogs (group A) these indicators were administered separately as bolus injections into a cannulated diagonal branch of the left anterior descending coronary artery (LAD) and the curve of the response function was recorded by external activity registration.

Plasma perfusion coefficients calculated by kinetic analysis of response curves from 99mTc-DTPA SIRD experiments (group A) were on average 98 v 102 ml.min-1.100 g-1 in 51Cr-EDTA experiments, in good agreement with the average plasma flow rate of 92 ml.min-1.100 g-1 determined by local 133Xe washout technique.
