Detection of Focal Hypometabolism and Lateralization of Epileptic Foci
| Detection of focal hypometabolism | |||
| Method | Ipsilateral | Bilateral | Correct lateralization |
| Visual | 20 | 4 | 18/20 (90) |
| SPMP < 0.001 (uncorrected) | 20 | 12 | 20/20 (100) |
| SPMP < 0.0001 (uncorrected) | 19 | 8 | 19/20 (95) |
| SPMP < 0.05 (corrected) | 15 | 3 | 12/20 (60) |
Data in parentheses are percentages. In patients with bilateral hypometabolism on SPM, lateralization was determined by side of most severe hypometabolism (highest z value).
