Table 3. Comparison of tumor extent defined by 18F-FLT uptake in PET image and abnormal signal change on MR image.
| Outcomes | N (%) |
|---|---|
| 18F-FLT uptake corresponding exactly to contrast-enhancement | 2 (10.53%) |
| 18F-FLT uptake beyond abnormal contrast-enhancement | 14 (73.68%) |
| Abnormal contrast-enhancement beyond 18F-FLT uptake | 16 (84.21%) |
| 18F-FLT uptake corresponding exactly to hyperintensity areas | 0 (0%) |
| 18F-FLT uptake beyond hyper-intensity areas | 8 (42.11%) |
| Hyper-intensity areas beyond 18F-FLT uptake | 19 (100%) |
