Hypothesis

The study aims to compare the transmural extent of T2-hyperintensity on CMR with the transmural extent of infarction.

Conclusion

T2-hyperintensity is often not transmural and closely relates to the extent of infarction, raising concerns about its use in assessing the area-at-risk.

Supporting Evidence

  • 59% of subjects showed transmural T2-hyperintensity.
  • 56% of subjects had transmural hyperenhancement.
  • 30.3% of slices showed transmural T2-hyperintensity.
  • 32.0% of slices showed transmural hyperenhancement.

Takeaway

The study looked at how much swelling in the heart matches with heart damage, finding that swelling doesn't always cover the same area as the damage.

Methodology

34 canines underwent coronary occlusion followed by reperfusion, with imaging performed post-MI to assess T2-hyperintensity and infarction.
