T1, T2 mapping and multi-b DWI are novel CMR technologies with different advantages on myocardium viability evaluation. The aim of this study is to evaluate myocardial viability using T1, T2 mappings, and multi-b DWI, and explore the characteristics of pre-contrast T1, ECV, T2 and ADC values for patients with recent, sub-acute and chronic myocardial infarction. From this preliminary study, it is not hard to quantitatively identify the infarcted myocardium from the normal, but hard for the reperfusion reversible myocardium around the infarction zone. Its been demonstrated ECV has a high correlation with the findings of LGE comparing with other parameters.
