Development of MRI-guided electro-physiology procedures
for atrial fibrillation ablations requires robust MRI
techniques for intra-procedural evaluation of acute
cardiac ablations. LGE-MRI has been used to visualize
ablation related tissue changes but it requires contrast
infusion limiting repeatability. In this study, we
demonstrate that non-contrast T1-weighted technique can
be used to visualize acute cardiac RF lesions.
