Comparison of Localization Results of Visual Assessment and SPM Analysis of 18F-FDG PET
| SPM analysis* | Visual assessment | ||||||
|---|---|---|---|---|---|---|---|
| Correct localization | Lateralization only | Failure to lateralize or localize | |||||
| Correct localization | 12 | 3 | 4 | 19 | |||
| Failure to localize | 4† | 1† | 5 | 10 | |||
| 16 | 4 | 9 | 29 | ||||
* P < 0.005 (uncorrected) at voxel height of threshold with cluster size > 50.
↵† Cases that were not acceptable for normalization and were considered as localization failure.
