Methods The left coronary artery (LCA) of 15 rats was occluded for 20 to 30 min, followed by reperfusion. After 2 weeks, 99mTc-AV was injected, and then 1 h later, 201Tl was injected after reocclusion of the LCA. Dual-tracer autoradiography was performed to assess 99mTc-AV uptake and the area at risk (AAR) by 201Tl defect. 99mTc-AV uptake ratio was calculated by dividing the count density of the AAR by that of the normally perfused area. In short-axis LV slices, LV cavity dilation index (DI) was calculated by dividing the area of LV cavity by that of the whole LV area. LV wall-thinning ratio (WTR) was calculated by dividing the LV wall thickness in the AAR by that of the normally perfused area. Results Significant 99mTc-AV uptake in the AAR was observed in 10 rats. DI was significantly higher in rats with positive 99mTc-AV uptake than in rats without uptake. WTR was smaller in rats with positive 99mTc-AV uptake than in rats without uptake.
