Key result
Early 99mTc-RIP uptake post-MI colocalizes with eventual 1-year scar formation in ~70% of patients.
Why the study?
The clinical feasibility of noninvasive imaging of interstitial alterations after myocardial infarction using a technetium-99m-labeled RGD imaging peptide was assessed.
Does early molecular imaging with technetium-99m-labeled RGD imaging peptide predict the extent of scar formation in patients after myocardial infarction?
Observational (n=10)
No
Does early molecular imaging with technetium-99m-labeled RGD imaging peptide predict the extent of scar formation in patients after myocardial infarction?
Early RGD-based molecular imaging after myocardial infarction may predict the eventual extent of scar formation at 1 year.
No takes yet. Share an insight, caveat, or question.
Early 99mTc-RIP uptake may predict post-MI scar extent; hypothesis-generating and requires prospective validation before clinical adoption.
Verjans et al. (2010) conducted an observational in Acute myocardial infarction (n=10). 99mTc-labeled RGD imaging peptide (RIP) imaging vs. Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) imaging was evaluated on Colocalization of early RIP uptake with eventual scar formation by LGE-CMR. In 7 of 10 patients after their first myocardial infarction, 99mTc-RIP uptake at 3 and 8 weeks colocalized with the eventual extent of scar formation observed at 1 year by delayed contrast-enhanced magnetic resonance imaging.
