The pre-LA and post-LA MR images of the target lesion are shown. a An arterial-phase axial MRI shows a hyper-enhanced lesion was located at the hepatic segment VIII (arrowhead). b The lesion (white arrowhead) with a high signal on T2WI is adjacent to the IVC (red arrowhead). c A portal-phase axial MRI after trans-IVC LA shows a non-enhanced ablation area (white arrowhead) with intact morphology and blood perfusion of the punctured IVC (red arrowhead)
