Macro-regenerative nodules in biliary atresia: CT/MRI findings and their pathological relations

Figure 1 A 3-year-old BA girl with segments 5-8 (asterisk) and segment 2 (arrow) MRN. A: The density of the MRN is slightly higher than that in the surrounding liver parenchyma during pre-enhanced phase of the CT; B: FSE/T2WI MRI shows a lower signal intensity in the MRN than in the surrounding liver; C: During portovenous phase of the CT, the tubular structure and splaying portal veins can be seen in the MRN (arrowhead); D: The explanted liver and intra-tumoral portal tract can be seen (arrowhead).
