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.
