FIGURE 3. (A) Short-axis images from apex (left) to base (right) in rat with permanent left coronary occlusion (1 d after myocardial infarction). 18F-FDG PET shows an uptake defect, and delayed-enhancement MRI (ce-MRI) demonstrates hyperenhanced area in corresponding anterior wall indicated by fused images (arrows). Corresponding histologic sections stained with hematoxylin–eosin reveal the infarct area as a poorly stained area. (B) Polar map views of 18F-FDG uptake (left) and of infarct area (blue) determined by threshold analysis using 6 SDs (right). Examples of tracing of LV region (red) and infarct area (blue) are displayed in C (ce-MRI) and D (histology).
