FIGURE 1. Initial ^99mTcN-NOET myocardial uptake after bolus injection in isolated rat hearts perfused with KH buffer (control; n = 6), KH with FA-free BSA 0.03% (n = 5), or BSA 0.03% (n = 4). Myocardial ^99mTcN-NOET uptake was reduced in presence of BSA and reduction was not dependent on degree of lipid loading.
