WebThe goal of this study was to measure CSF velocities at multiple cervical spinal levels in patients with Chiari I malformation. Materials and methods: In a patient registry, consecutive patients without surgery who had PCMR flow images in 5-8 axial planes between the foramen magnum and C4 were identified. Four contiguous regions were defined ... WebAug 3, 2000 · Cerebrospinal fluid flow patterns were evaluated at four regions of interest: prebulbar cistern, foramen magnum, and the ventral and dorsal spinal subarachnoid spaces at the C-5 level. A temporal analysis of CSF flow waveforms was performed with measurement of cranial- and caudal-directed flow durations.
