From: Current T1 and T2 mapping techniques applied with simple thresholds cannot discriminate acute from chronic myocadial infarction on an individual patient basis: a pilot study

Fig. 2

a and b. Thresholds that discriminate normal from abnormal T1 and T2 relaxation times for every myocardial pixel were defined based on reference T2-and T1-values from healthy controls. These thresholds were applied on the T2- and T1-maps so that all abnormal pixels in the myocardium (between the red and green contour) that were outside the normal range became highlighted in a color (blue in T2-map, brown in T1-maps). The red arrows in the LGE images highlight the infarct region. Note that patient #2 had an old inferior infarction (red asterisk) but actually presented with LAD occlusion. Patient 5 had microvascular obstruction with hemorrhage (white arrow). a = subjects 1-4; b = subjects 5-8
