On the bulk motion of the cerebrospinal fluid in the spinal canal
Journal of Fluid Mechanics, 2018 Radionuclide scanning images published in Nature by Di Chiro in 1964 showed a downward migration along the spinal canal of particle tracers injected in the brain ventricles while also showing an upward flow of tracers injected in the lumbar region of the

Verification Of Measurements Of Lumbar Spinal Dimensions In T1- And T2-weighted Magnetic Resonance Imaging Sequences [PDF]
, 2014 BACKGROUND CONTEXT: Magnetic resonance imaging (MRI) is commonly used to assess patients with lumbar spinal stenosis. No single MRI sequence has been shown to be superior in spinal canal measurements.
