Delayed Myocardial Enhancement-Ischemic versus Non-ischemic Myocardium-Teaching Point

Delayed enhancement MRI has an important role in establishing the diagnosis of ischemic versus nonischemic myocardial disease.  The differentiation between ischemic and nonischemic cardiac diseases is essential for guiding clinical management.  

The expected pattern of delayed enhancement in patients with ischemic heart disease follows a coronary artery territory distribution. The delayed enhancement initially involves the subendocardial region and can progress to a transmural abnormality.
Patchy or diffuse delayed enhancement that does not follow a coronary artery distribution and primarily involves the midwall and/or subepicardial regions of the left ventricular (LV) myocardium is a characteristic finding of nonischemic cardiomyopathies.
