Figure 1From: Transmural perfusion gradient analysis by high-resolution MR versus fractional flow reserve for the assessment of coronary artery stenosis(A) Scatterplot showing the distribution of FFR values according to the results of transmural perfusion gradient analysis (FN: false negative; TN: true negative; TP: true positive; FP: false positive). (B) Scatterplot showing the distribution of MPR values according to the results of transmural perfusion gradient. A dichotomous cut-off of 0.80 was used to signify a significant lesion.Back to article page
