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.
