Fast ²³ Na Magnetic Resonance Imaging of Acute Reperfused Myocardial Infarction

Abstract

Following acute infarction with reperfusion, a regional increase in 23Na MR image intensity is associated with nonviable myocardium. Fast gradient-echo imaging techniques reduce 23Na imaging times to a few minutes, suggesting that 23Na MR imaging has the potential to become a useful experimental and clinical tool.
