Acute noncontrast T1-weighted magnetic resonance imaging predicts chronic radiofrequency ablation lesions.
Magnetic resonance imaging (MRI) has been used to visualize radiofrequency (RF) ablation lesions but the relationship between volumes that enhance in acute MRI and the chronic lesion size is unknown. ⋯ Native T1w MRI acquired acutely after RF ablation is a good predictor of chronic lesion size. Acute LGE-MRI significantly overestimates the chronic lesion size.
