Spine MR imaging findings for three different sequences in the patient cohort
| T2WI | 3D T2WI FS | T1WI Gd FS | |
|---|---|---|---|
| Sequence available in all patients | 96/103 (93%) | 96/103 (93%) | 75/103 (73%) |
| Sequence available in patients with leaks | 65/70 (93%) | 64/70 (91%) | 45/70 (64%) |
| Craniocaudal extent of the CSF leak (mean No. of vertebrae) | 7.7 ± 6.2 | 8.5 ± 6.9 | 7.5 ± 6.7 |
| Interrater agreement for the presence of a CSF leak | 0.84 | 0.91 | 0.82 |
| Interrater agreement for the location of the CSF leak | 0.29 | 0.67 | 0.62 |
| Mean number of suspicious lesions potentially causing CSF leakage | 4.3 ± 3.0 | 5.6 ± 3.9 | 5.1 ± 4.2 |
Note:—T2WI indicates T2-weighted; 3D T2WI FS, three-dimensional, isotropic, T2-weighted turbo SE sequence with fat saturation; T1WI Gd FS, isotropic T1-weighted blocks with fat saturation after intrathecal application of gadolinium.
