Image intensity quantification on POD 5, 10 and 15 following gene transfer or UW only perfusion. Data are expressed as percentage of injected dose of ¹²³I per gram of heart tissue (%ID/g). Image intensity was significantly higher in the Ad-NIS, Ad-NIS-CEA, Ad-NIS-CG than UW only perfused hearts on POD 5 and 10 (*p<0.05, t-test). No differences in radioiodine uptake between the groups were noted on POD 15 imaging comparing UW group with either Ad-NIS or Ad-NIS-CEA or Ad-NIS-CG group (t-test).
