WebMay 1, 2014 · The traditional understanding of CSF physiology assumes that 80% of CSF is secreted by the choroid plexus into the ventricular cavities. Other structures, e.g. the brain parenchyma, add the remaining 20%. The rate of CSF formation in humans is 0.3 – 0.4 ml min -1, and the total CSF volume is 90 – 150 ml in adults. WebMay 2, 2004 · One thing that must be considered for CSF flow analysis using 2D cine phase-contrast MR imaging is the possible residual systematic errors caused by imperfect suppression of eddy currents or brain motion. Therefore, to correct these possible residual systematic errors, a background baseline region representing the apparent velocity in a …
