Mean metabolite levels within abnormal perfusion and T2h regions compared with contralateral NAWM for grade IV gliomas
| Region | Choline | Creatine | Lactate | No. Voxels |
|---|---|---|---|---|
| aPH | 17.6 ± 10.2 | 9.1 ± 5.6 | 4.3 ± 2.3 | 54 ± 43 |
| aRec | 15.9 ± 7.7 | 8.2 ± 4.7 | 4.3 ± 2.7 | 50 ± 70 |
| aPH+aRec | 16.1 ± 8.6 | 8.1 ± 4.9 | 4.8 ± 3.3 | 24 ± 38 |
| T2h | 14.4 ± 6.4 | 9.0 ± 4.7 | 3.4 ± 2.5 | 172 ± 117 |
| NAWM | 16.4 ± 4.5 | 14.5 ± 3.6 | 1.2 ± 1.9 | N/A |
Note:—aPH indicates the region of abnormal peak height with normal recovery; aRec, the region of abnormal recovery with normal peak height; NAWM, normal-appearing white matter; N/A, not applicable.
