Figure 3 Transmural distribution of regional FDG deposition in pigs with hibernating myocardium. There was a marked transmural gradient in FDG deposition (extraction x flow) in the hibernating LAD regions (black squares) with regionally increased deposition in the inner two-thirds of the myocardial wall in each group. There were no significant differences in FDG deposition between groups of animals (3 months, n = 12; 4 months, n = 18; 5 months, n = 6) in any region or mural layer. FDG = ¹⁸F-2-deoxyglucose; LAD = left anterior descending coronary artery.
