“During ablation, MRI images provide a better view of the anatomy of the heart and the instruments used for treatment, but also of the changes made to the treated cardiac tissue. Unlike X-ray images, the entire area surrounding the heart can be seen, including the blood vessels and valves. And the MRI offers the opportunity during the procedure to visualize the effects of the treatment on the myocardial tissue.”
Hopman et al. (Tue,) studied this question.
