Figure 1 Examples of Reconstructed Polar Maps for 2 Patients
In each set, the top panels are the raw perfusion (left) and raw F-18-fluorodeoxyglucose (FDG) uptake (right) polar maps; the middle panels are the normalized perfusion (left) and FDG uptake (right); the lowest panels are the scar score (left) and mismatch score (right); color scale in the lower panel is shifted to allow visualization of defects (this does not affect the score determinations). (Patient A) Predominantly scar in the anteroseptal are inferolateral walls and apex. Of the total left ventricular (LV) myocardium; 31% was scar and 3% was mismatch. Interpretation was that there was a large scar and a small amount of hibernating viable myocardium and that the patient would not be expected to improve after revascularization. (Patient B) Partial mismatch (mixture of scar and hibernating myocardium) in the large defect involving the inferior wall and apex and extending to the anteroseptal wall. Of the total LV myocardium; 8% was scar and 18% was mismatch. The interpretation was that there was a large amount of hibernating viable myocardium and that the patient would be expected to improve after revascularization.
