Irreversible electroporation (IRE) is a new technique
for minimally invasive local tissue ablation.
Multi-contrast MRI has potential to non-invasively
monitor IRE procedures. The purpose of this study was to
evaluate multi-contrast (T2w, T1w pre and post contrast
agent, and diffusion weighted imaging (DWI)) MRI for
characterizing tissue ablation zones created by
irreversible electroporation (IRE) in normal pig liver
and correlate with histopathology. We found that IRE
ablation zones were clearly visualized with multiple MRI
contrasts and lesion short axis from both T2w and T1w
MRI were correlated with pathology.
