Table 1:

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.
