It is the purpose of this study to visualize and quantitatively evaluate left atrial cryoablation lesions with late gadolinium enhanced cardiac MR using commercially available pulse sequences. The individual pulmonary veins of 10 subjects were included. In particular, consideration is given to acquisition parameters such as the timing of image acquisition post ablation. Significant LGE scar was observed on the majority of the 10 pulmonary veins with well visualized lesions.
