Estimates of intermodality and interrater agreement
| Modality | Intermodality agreement (95% CI) | Intermodality clinical significance | Interrater agreement (95% CI) | Interrater clinical significance |
|---|---|---|---|---|
| 95% confidence intervals (CI) are one-sided. | ||||
| CT, computed tomography; DWI, diffusion-weighted imaging; FLAIR, fluid attenuated inversion recovery. | ||||
