This presentation is targeted at those interested in phase contrast magnetic resonance imaging (PC-MRI) and cerebrospinal fluid (CSF) flow dynamics. Queckenstedtfs testis a clinical procedure used to diagnose spinal stenosis. If stenosis is present in the spine, there will be a damped, delayed response in the lumbar puncture indicating a positive Queckenstedtfs test. An increase in the CSF pressure indicates a change in the CSF flow dynamics. The purpose of this study is to measure the change in the CSF flow dynamics using PC-MRI when both jugular veins are compressed.
