This work presents the use of non-contrast MRI sequences to detect and identify acute lesions caused by RF ablation in the heart. Canine experiments were performed to investigate how soon after delivery of RF power MRI can visualize lesion and whether it is observable in the atrium of the heart. Preliminary results indicate that acute lesion in the atrium of the heart can be visualized within a minute of delivering RF energy.
