Visualization of ablation lesions with single-shot native contrast imaging, suitable for monitoring lesion placement during an ablation procedure. a Gross pathology and b ex vivo imaging of two RF ablation lesions (green arrows) and one chemoablation lesion (orange arrow), c in vivo 3D navigator gated T1w imaging shows good correspondence to the lesion core regions on ex vivo assessment. The chemoablation lesion has higher contrast compared to RA ablation lesions. d,e in vivo single-shot imaging with 2-RR triggering in both short axis (SAx) and horizontal long axis (LAx) corresponds well to in vivo 3D imaging This suggests visualization of lesions immediately after and likely during formation is feasible with 2-RR triggering, particularly for higher contrast chemoablation lesions. Additional files 4 and 5: Video S1 display a time series of the images (d)
