At a given field strength tissues present with specific T1-values. We hypothesize, that infarcted myocardial tissue can be delineated from normal myocardium by means of T1-maps in unenhanced and contrast-enhanced (Gadobutrol) scans. Analysis of T1-values was performed for normal myocardium (MYO), infarcted myocardium (CMI) and the left ventricular cavity (LVC). In addition T1-ratios of MYO/LVC and CMI/LVC were calculated. T1-values of MYO and CMI and the calculated ratios of MYO/LVC and CMI/LVC were significantly differenent in pre-contrast and post-contrast scans. MR-measurements of T1-values with the LVC as a reference allow for a differentiation of infarcted areas from normal myocardial tissue.
