Comparison of a neuroradiologist's subjective impression of language lateralization from fMRI compared with known lateralization, conducted without (top half) and with (bottom half) the use of CLIa
| Known Lateralization | Neuroradiologist's Subjective Impression | |
|---|---|---|
| Left | Nonleft | |
| Without CLI | ||
| Left | 77 (0.44) | 11 (0.06) |
| Nonleft | 28 (0.16) | 60 (0.34) |
| With CLI | ||
| Left | 81 (0.46) | 7 (0.04) |
| Nonleft | 27 (0.15) | 61 (0.35) |
↵a The numbers refer to the total assessments obtained after review of all 8 neuroradiologists with all 22 studies, for a total of 176 comparisons. The number in parentheses is the corresponding fraction. Lateralization was dichotomized into 2 categories of either left or nonleft lateralization, with the latter group combining bilateral and right lateralization (ie, any examination with some component of right-sided activation).
