- Resisted Inspiration Improves Visualization of CSF-Venous Fistulas in Spontaneous Intracranial Hypotension
This retrospective cohort of patients with observed or suspected CSF-venous fistula identified during standard maximum suspended inspiration CT myelography were rescanned using resisted inspiration and the Valsalva maneuver. Visibility of the CSF-venous fistula was greatest during resisted inspiration in most of the cases.
