Comparison of mean metabolite levels within abnormal perfusion and T2h regions from voxels across all patients of each grade
| Region | Choline | Creatine | ||
|---|---|---|---|---|
| Grade III | Grade IV | Grade III | Grade IV | |
| aPH | 16.9 ± 9.6 | 16.5 ± 12.1* | 10.7 ± 5.8 | 7.6 ± 5.9** |
| aRec | 17.9 ± 11.2 | 16.0 ± 9.4 | 8.8 ± 5.0 | 8.2 ± 4.8 |
| aPH+aRec | 20.6 ± 12.8 | 19.0 ± 11.7 | 11.2 ± 6.9 | 8.4 ± 5.4* |
| T2h | 18.9 ± 10.7 | 13.6 ± 8.7 | 11.0 ± 5.6 | 8.5 ± 5.5 |
Note:—aPh indicates the region of abnormal peak height with normal recovery; aRec, the region of abnormal recovery with normal peak height.
