Magnetic resonance imaging of cerebrospinal fluid volume and the influence of body habitus and abdominal pressure.


BACKGROUND Although the cerebrospinal fluid (CSF) is the pathway of anesthetic delivery and the diluent for neuraxially administered drugs, little is known about its volume, including variability among individuals, longitudinal distribution, or influence of body habitus. Models made to investigate subarachnoid anesthetic distribution lack valid dimensions… (More)
