Figure 3 The transmural extent of delayed enhancement is inversely related to quantitative regional wall thickening (a: acute study, b: chronic study, p < 0.001 for both trends). For segments with <1 mm of wall thickening on the acute study, the improvement in wall thickening is much greater for segments that appear normal on delayed enhancement images compared with abnormal segments (c). There were too few segments with residual severe wall motion abnormalities on the acute study with <50% transmural extent of delayed enhancement to allow further stratification of the change in wall thickening (WT).
