The entire spine is scanned up to 24 hours in cases of spontaneous intracranial hypotension, spinal trauma, or postoperative CSF leaks. Fast CSF leaks have rapid contrast diffusion and may not be localized to a 2-vertebral segment of the spinal canal (suitable for local treatment by extradural blood patch or alternate therapy) by routine postmyelogram CT spine scan. CSF is produced at a rate of approximately 20 mL/h for a total of approximately 500 mL daily. This occurred on bed linen, filter paper, absorbent paper, and coffee filters.

High-Resolution Computed Tomography as an Initial Diagnostic and Localization Tool in Patients with Cerebrospinal Fluid Rhinorrhea: A Meta-Analysis. Localization of the leak to the right or left nasal cavity may be difficult because of the tendency of the fluid to cross sides and flow from both nostrils. HHS Vulnerability Disclosure, Help Surg Neurol. Rapid echo-planar imaging with the patient in the prone position and performing a Valsalva maneuver may allow for limited coronal imaging and increase the accuracy of MR cisternography. Beta-2 transferrin is the most reliable confirmatory test for CSF leak. If CSF is present, a dextrose stick test may be positive. 1979 Oct 25;97(40):1814-20.
