The concept of fat contained within the myocardium, has recently received attention because of its potential role in diabetic myocardial disease, obesity, and HIV infected individuals. Measurements of myocardial triglycerides in humans have been accessed using proton MR spectroscopy (1H MRS). We studied the accuracy of the dual-echo Dixon MRI in quantifying the fatty content of the myocardium in autopsies and patients. 1H MRS as an independent method was also applied for comparison.
