Comparing MRI characteristics of the no-flow region in reperfused and non-reperfused myocardial infarctions

This article establishes a comparison between the magnetic resonance imaging and histopathologic characteristics of the no-flow region (NF) in reperfused and non-reperfused myocardial infarctions.

Key points:

• The no-flow region (NF) is characteristic of both reperfused and non-reperfused myocardial infarct (MI)
• The size of the NF is significantly reduced in the post-contrast period
• The relative size of the NF and the uptake of contrast in the NF are similar in both models
• There is excessive calcification and haemorrhage in the NF in reperfused MI, but not in non-reperfused MI
