Figure 5
ROC analysis of the diagnostic performance of T1 mapping and LGE imaging in the detection of MI (using TTC staining as the gold standard). Legend: ROC analysis shows the diagnostic performance of T1 mapping compared to the LGE technique in detecting MI at segmental level against TTC staining as the gold standard. T1 mapping had an AUC of 0.89. The cut of value of 1124 ms had a highest Youden index (0.719), with a sensitivity of 75.6% and a specificity of 96.3%. There was no significant difference between the two techniques in AUC for the detection of MI.
