Craniocaudal spinal cord motion per heartbeat was larger at segment C2/C3 (peak-to-peak amplitude 7.30 {\textpm} 2.4 vs 5.82 {\textpm} 2.0 mm/s, total displacement 1.01 {\textpm} 0.4 vs 0.74 {\textpm} 0.4 mm, p = 0.006, respectively) and at segment C5/C6 (total displacement 1.41 {\textpm} 0.7 vs 0.97 {\textpm} 0.4 mm, p = 0.021).Discussion SLEC-positive patients with SIH show higher CSF flow and higher spinal cord motion at the upper cervical spine. This increased craniocaudal motion of the spinal cord per heartbeat might produce increased mechanical strain on neural tissue and adherent structures, which may be a mechanism leading to cranial nerve dysfunction, neck pain, and stiffness in SIH. Noninvasive phase contrast MRI of CSF flow and spinal cord motion is a promising diagnostic tool in SIH.Trial Registration Information German Clinical Trials Register, identification number: DRKS00017351.Classification of Evidence This study provides Class III evidence that noninvasive phase contrast MRI of the upper spine identifies differences in CSF flow and spinal cord motion in patients with SIH compared with healthy controls.AUROC=area under the curve of receiver operating characteristic; BMI=body mass index; CNN=convolutional neural network; CSA=cross-sectional area; ICC=intraclass correlation coefficient; ICHD=International Classification of Headache Disorders; SIH=spontaneous intracranial hypotension; ROI=region of interest; SLEC=spinal longitudinal extradural fluid collection; VENC=velocity ENCoding (parameter)}, issn = {0028-3878}, URL = {//www.ez-admanager.com/content/100/7/e651}, eprint = {//www.ez-admanager.com/content/100/7/e651.full.pdf}, journal = {Neurology} }
