Excerpt

Cardiac RF ablation is a widely accepted procedure for treatment of ventricular tachycardia and atrial fibrillation. Late gadolinium enhanced MRI (LGE-MRI) can be used to assess RF ablation lesions. However, LGE-MRI requires contrast injection and the visibility of lesions and appearance considerably change with time after the injection. Recently, native (non-contrast) T1-weighted (T1w) MRI was proposed to visualize RF lesions immediately post-ablation. The main aim of this work was to study how the visibility and volume of RF lesions in native T1w MRI changes with time after ablation. …
