Quantitative assessment of microvascular obstruction by T1-mapping. Panel A shows a case of microvascular obstruction as depicted by LGE. The corresponding T1-map is shown in Panel B. The dark core of MO in the LGE image (arrows) is depicted by T1 values (Panel B) in the color range similar to remote myocardium (green). The surrounding injured myocardium (bright on LGE) shows high T1 values (red). Panel C shows quantitative analyses of the 7 cases with MO. T1 values in the MO regions are significantly lower than in the surrounding LGE-positive myocardium.
