FIGURE 4. Graphs show results for monoexponential analysis of *Cu-ATSM PET (protocol I) (A), kinetic modeling analysis of *Cu-ATSM (protocol I) (B), monoexponential analysis after injection of *Cu-ATSM (protocol II at 3 h) (C), and kinetic modeling analysis after injection of *Cu-ATSM (protocol II at 3 h) (D). Global hypoxia increased tracer retention (B). In each animal, LAD occlusion significantly decreased MBF and concomitantly increased tracer retention. Individual (joined points) and mean values for all animals (far right and far left) of myocardial retention of *Cu-ATSM are given. SD error bars associated with each animal are on individual points; if not seen, bars are within symbol.
