Perfusion MRI at rest in subacute and chronic myocardial infarct.

ConclusionPerfusion is decreased in subacute reperfused infarct tissue compared to normal tissue. K(trans) is not decreased, consistent with increased surface area of the vascular bed of the subacute infarct. Infarct tissue v(e) is increased, and decreases with scarring. The presence of persistent MO correlates to more pronounced perfusion reduction and results in delayed contrast arrival, indicating microvascular collateral circulation.
