Cardiovascular magnetic resonance (CMR) imaging offers precise visualization of cardiac anatomy, function, and tissue composition. Interventional CMR (iCMR) holds potential for real-time, radiation-free myocardial ablation guidance, yet limitations in direct in-vivo tissue assessment have limited progress.
