How could a cardiac MRI scan help my doctor diagnose a cardiac condition?

An MRI scan of your heart could, in theory, help your doctor decide if you are a good candidate for an implantable cardioverter-defibrillator (ICD) or for a procedure called pulmonary vein isolation that can help halt atrial fibrillation.

A cardiac MRI is painless, and doesn't expose you to any radiation. But it can be a bit of a hassle, and it takes time. I suggest that you ask your doctor why he thinks you need a cardiac MRI and what you would get out of it.
