Organ clearance kinetics from imaging quantification in normal dogs administered 99mTcN-MPO (a) or 99mTc-Sestamibi (b). The liver activity of 99mTcN-MPO was markedly decreased within the first 60 min, whereas 99mTc-Sestamibi had a slower reduction in liver activity over time. A mild myocardial washout was observed in the dogs administered 99mTcN-MPO. No significant myocardial washout was seen in the dogs administered 99mTc-Sestamibi.
