Periportal thickening on magnetic resonance imaging for hepatic fibrosis in infantile cholestasis

Figure 2 Representative images of periportal thickening for each hepatic fibrosis grade. The maximal thickness (double arrow in each figure) of periportal signal intensity change was measured. A: 2.7 mm on axial T2-weighted image in a 7-d-old girl with non-biliary atresia (non-biliary atresia, choledochal cyst) and hepatic fibrosis grade 1 (F1); B: 4.2 mm on T2-weighted axial image in a 2-mo-old girl with BA and F2; C: 5.5 mm on T1-weighted axial image in a 3-mo-old girl with biliary atresia and F3; D: 5.4 mm on T2-weighted axial image in a 2-mo-old girl with non-biliary atresia (metabolic disease) and F4.
