Proton MR spectroscopy metabolite ratios of lesions (and controls)
| Patient No. | NAA/Cr | Cho/Cr | Glx/Cr | Lac | Lip |
|---|---|---|---|---|---|
| 1 | 2.2 (1.9) | 2.0 (0.6) | 1.2 (0.5) | + | + |
| 2 | 1.6 | 1.1 | 1.1 | + | − |
| 3 | 2.1 (1.6) | 1.2 (0.8) | 1.5 (0.4) | ++ | + |
| 4 | 1.6 | 1.4 | 1.0 | + | + |
Note:—NAA indicates N-acetylaspartate; Cr, creatine; Cho, choline; Glx, glutamine and glutamate; Lac, lactate; Lip, lipid; +, mildly elevated; ++, markedly elevated; −, not evident.
