Late Gadolinium Enhancement (LGE) MRI is frequently used to assess acute injury from RF ablation in the left atrium. In this work, we strive to determine the accuracy of the LGE MRI technique used to determine the gaps between acute lesions to optimize and improve the real-time MRI guided targeted RF ablation of lesion gaps.
