WebBoth T1 and T2 mapping require multiple images to be obtained at various TR or TE times, respectively, to calculate a relaxation curve, which can then be displayed as an absolute value for a given region of the heart or as an image with an overlaying color map representing the relaxation time [ 14, 15] ( Fig. 3 ). WebT2 black-blood / short tau inversion recovery (STIR) imaging: Focal myocardial edema can be seen in the apical and mid free lateral wall on T2 black-blood images (blue arrowheads) and not so obvious in the STIR images (blue arrows). It can be visualized with a color map.
