Distinction of salvaged and infarcted myocardium within the ischaemic area-at-risk with T2 mapping

Abstract

T2 relaxation parameters are different in the infarcted and salvaged myocardium, and both are significantly longer than remote. Furthermore, the magnitude of increase in T2 was less in the salvaged myocardium after longer reperfusion, indicating partial resolution of oedema in the first 48 h after reperfusion.
