Number of radiomic features under each class that differentiated (P < 0.05) the immunotherapy group (T + M + Tx) and untreated group (T + M). Radiomic analysis was performed on nanoparticle contrast–enhanced delayed CT, CT angio, and noncontrast T2-weighted MR images.
| Radiomic feature class | CT delayed | CT angio | T2w MRI |
| First-order statistics | 0 | 2 | 1 |
| Gray level co-occurrence matrix (GLCM) | 0 | 0 | 1 |
| Gray level dependence matrix (GLDM) | 2 | 2 | 1 |
| Gray level run length matrix (GLRLM) | 2 | 2 | 1 |
| Gray level size zone matrix (GLSZM) | 5 | 6 | 1 |
| Neighboring gray tone difference matrix (NGTDM) | 1 | 1 | 0 |
