FIG. 3

Orthogonal slices of the same rat. a: Short-axis orientation. b: Horizontal long axis. c: Vertical long axis. Where the SPECT scan shows a perfusion deficit (upper row), the PET images (lower row) show an increased tracer uptake in the border zones (arrows) relative to the normal myocardium. Note that the activity on the left side of the middle SPECT image (column b, upper row) derives from liver tissue, whereas the activity on the far right side of the middle PET image (column b, lower row) derives from granulation tissue at the chest wall.
