Answer

MRI with gadolinium–diethylene-triamine pentaacetic acid (DTPA) has been used to evaluate the extent of mid-wall fibrosis, which may correlate with risk of arrhythmias and failure to respond to treatment. Further investigation is ongoing in the role that subendocardial sparing mid-wall fibrosis plays in the pathogenicity of arrhythmias. In the future, MRI with gadolinium may be used for the risk stratification of patients with dilated cardiomyopathy. [82]
