WebApr 13, 2024 · All patients were preoperatively evaluated by phase contrast cine-MRI to study the CSF flow and enhanced MRI to assess possible arachnoiditis. A complete spinal cord MRI was also obtained. There were 84 patients (85.7%) with CM Type 1 (CM-1), while CM Type 1.5 (CM-1.5) was identified in 14 patients (14.2%). Time-resolved 2D phase-contrast imaging with velocity encoding is the most widely used method and relies upon location-specific sequential application of a pair of phase encoding pulses in opposite directions. Stationary protons will experience the same pulse at both times and therefore return no … See more Quantification of flow can be generated by defining a region of interest (e.g. cross-sectional area of the aqueduct of Sylvius) and charting velocity … See more The following clinical situations can benefit from CSF flow studies 2: 1. aqueduct stenosis 2. normal pressure hydrocephalus … See more
