Characterisation of acute myocardial infarction by gated magnetic resonance imaging.
In studies with gated nuclear magnetic resonance imaging, patients with recent transmural myocardial infarction showed significantly longer spin-lattice relaxation times (T1) in the infarct area than did healthy volunteers or patients with non-ischaemic or chronic ischaemic heart disease. 10 of the 13 patients had a T1 longer than that found in any healthy subject or in any patient with other heart disease. Changes in T1 should prove useful in the assessment of interventions designed to limit infarct size.
