Implication

Randomized trial demonstrates high-contrast imaging of myocardial infarction in dogs, suggesting effective non-invasive diagnosis.

Key Points

The study aims to assess the ability of ECG-gated nuclear magnetic resonance imaging to distinguish between normal and infarcted myocardial tissue in vivo.
Seven dogs were studied using ECG-gated NMR imaging in vivo with a spin-echo technique.
Imaging was performed at 2 to 7 days post-ligation of the left anterior descending coronary artery.
No intravenous paramagnetic contrast agents were used during imaging.
In six dogs, anterior wall signal intensity was 66% greater than normal myocardium (p<.01).
The T2 relaxation time in infarcted myocardium was 69% longer compared to normal myocardium (p<.01).
One dog showed uniform signal intensity and had no evident infarct on postmortem examination.
