Delayed myocardial enhancement
Citation, DOI & article data
Delayed myocardial enhancement, as seen on cardiac MRI, occurs when gadolinium contrast material seeps into fibrotic or necrotic myocardial tissue. It is due to a number of etiologies, and has variable appearances.
- subendocardial enhancement indicates an ischemic etiology
- transmural enhancement is nonspecific, but suggestive of an ischemic etiology
- mid-wall enhancement indicates a non-ischemic etiology (e.g. myocarditis, idiopathic dilated cardiomyopathy)
- diffuse patchy areas of enhancement are seen in cardiac amyloidosis
