Quantitative assessment of NIC and dNIC in the proximal and distal regions of malignant and benign nodules in PP, AP, and VP.
| Group | Malignant nodules | Benign nodules | P value |
|---|---|---|---|
| ICPP | 11.128±6.509 | 14.381 ±7.010 | 0.089 |
| ICAP | 18.410±8.497 | 19.520 ±8.675 | 0.633 |
| ICVP | 17.440±5.637 | 18.620 ±9.952 | 0.619 |
| SDPP | 8.1723±2.176 | 7.891±1.297 | 0.591 |
| SDAP | 9.701±2.922 | 8.245±1.796 | 0.020 |
| SDVP | 8.457±2.292 | 7.535±1.426 | 0.060 |
| Longest diameter (mm) | 19.26±5.999 | 15.76±4.847 | 0.018 |
PP, pulmonary phase; AP, arterial phase; VP, venous phase; IC: iodine concentration; SD: standard deviation of iodine concentration in all nodules.
