a CT scans showing three hypervascular HCC nodules located in segment 8 and 7 as confirmed by selective angiography performed in the common hepatic artery. b Superselective catheterization performed with balloon microcatheter Occlusafe® (Terumo, Japan). The angiography performed with inflated balloon (post) detects more feeding vessels compared to angiography performed with deflated balloon (pre). c Syngo iFlow is applied to selective angiographies, performed before embolization with both deflated and inflated micro-balloon, showing an increase of peak time in the ROI-t located in the centre of tumour and the ROI-ihl located in the healthy parenchyma of the same segment
