Table 3. Summary of AR-based TI differences between tumor and healthy tissue and between adenocarcinoma and squamous cell carcinoma.
| Index | Tumor tissue | Healthy tissue | Adenocarcinoma | Squamous cell carcinoma |
|---|---|---|---|---|
| Homogeneity | - | + | + | - |
| Entropy | + | - | - | + |
| SRE | + | - | - | + |
| LRE | - | + | + | - |
| RLNU | + | - | - | + |
| LGZE | - | + | + | - |
| HGZE | + | - | - | + |
| SUVmax | + | - | - | + |
| MV | N/A | N/A | - | + |
N/A: not applicable
+: high in this tissue
-: low in this tissue
For instance (first row), homogeneity is higher in healthy tissue than in tumor tissue, and is also higher in adenocarcinoma than in squamous cell carcinoma.
