Representative 18F-FDG positron emission tomograms in a short-axis view, b vertical long-axis view, c horizontal long-axis view, and d bull’s-eye view. Before operation, the multiple area showed a sustained deficit. Six months after cell transplantation, the same areas show a restoration of glucose uptake, suggesting a return of myocardial viability with increased tracer intensity in the infarcted area after versus before cell infusion
