This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…
