Table 2 Comparison of portal venous phase computed tomography quantitative parameters between two groups, mean ± SD/median (interquartile rage)

Parameter	Stricture group (n = 23)	Non-stricture group (n = 176)	t/Z value	P value
PV-HU (HU)	128.6 ± 18.3	142.5 ± 21.6	-3.012	0.003
Liver-HU (HU)	89.4 ± 12.7	92.8 ± 14.2	-1.124	0.263
Aorta-HU (HU)	94.2 ± 15.8	92.6 ± 16.4	0.452	0.652
SV-HU (HU)	118.3 ± 16.9	132.7 ± 19.5	-3.452	0.001
Portal perfusion index	0.70 ± 0.09	0.66 ± 0.11	1.706	0.09
PV-HU/aorta-HU	1.38 ± 0.18	1.56 ± 0.22	-3.847	< 0.001
nPV-HU (%)	35.2 (28.6-42.8)	52.4 (41.6-64.3)	-4.126	< 0.001

PV-HU: Portal vein computed tomography value; Liver-HU: Hepatic parenchyma computed tomography value; Aorta-HU: Abdominal aorta computed tomography value; SV-HU: Splenic vein computed tomography value; nPV-HU: Normalized portal vein computed tomography value.
