Receiver operator characteristics (ROC)-analysis of segmental and global strain. To the left ROC curves for the detection of infarcted segments with scar transmurality exceeding 50% LGE (84 [34 patients of 116] out of 1856 segments) using circumferential strain from DENSE, FT and Tagging at end systole. To the right ROC curves for the detection of infarcted segments with scar transmurality exceeding 50% LGE (34 patients out of 116 patients) using global circumferential strain (GCS) from DENSE, FT and Tagging at end systole. AUC values are shown in the lower right corner with significance level *p < 0.05 and **p < 0.01
