Selection of myelographic technique based on spinal MRI findings
| SLEC | Likely cause of leak | Patient position | Technique |
| Present | Discogenic microspur Lateral or dorsal dural tear | Depends on distribution of SLEC | CTM, DSM, UFCTM |
| Absent | CSF-venous fistula | Lateral decubitus | CTM, DSM |
CSF, cerebrospinal fluid; CTM, CT myelography; DSM, digital subtraction myelography; SLEC, spinal longitudinal epidural collection; UFCTM, ultrafast CT myelography.
