The microsphere distribution results are summarized in this table. The distribution over LHA or S4A and RHA are shown for both catheter types. The column LHA/S4A targeting refers to LHA for experiments 1–3, and S4A for experiments 4–7. The deviation from homogeneous distribution (DHD) is the distance to a perfect homogenous distribution (50 %-50 %) in percentage points. Abbreviations: LHA = left hepatic artery; S4A = segment 4 artery; RHA = right hepatic artery; SMC = standard microcatheter; ARC = anti-reflux catheter
