| Parameters | TAA (mean ± SD) | ANHP (mean ± SD) | TNA (mean ± SD) | P |
|---|---|---|---|---|
| λHu | 3.32 ± 1.24*& | 0.71 ± 0.39# | 0.29 ± 0.27 | < 0.05 |
| NICAP (%) | 16.51 ± 6.75*& | 2.66 ± 2.05 | 2.28 ± 1.47 | < 0.05 |
| NICPP (%) | 46.68 ± 15.10*& | 39.48 ± 10.65# | 9.30 ± 7.46 | < 0.05 |
| ICD(mg/mL) | 0.56 ± 0.46*& | 1.49 ± 0.54# | 0.29 ± 0.36 | < 0.05 |
| AIF | 0.93 ± 0.31* | 0.18 ± 0.14# | 0.99 ± 0.86 | < 0.05 |
λHu, slope of the spectral Hounsfield unit curve; NICAP, normalized iodine concentration at arterial phase; NICPP, normalized iodine concentration at portal venous phase; ICD, iodine concentration difference; AIF, arterial iodine fraction; TAA, tumor active area; ANHP, adjacent normal hepatic parenchyma; TNA, tumor necrotic area.
*Indicates a significant difference between TAA and ANHP (P < 0.05).
#Indicates a significant difference between TNA and ANHP (P < 0.05).
&Indicates a significant difference between TAA and TNA (P < 0.05).
