title: Spinal descent of cerebrospinal fluid in man.
abstract: The descent of radiopharmaceuticals injected within the right lateral ventricle toward and into the spinal subarachnoidal spaces has been followed by scintiphotographic techniques and by computerized flow analysis in a group of "normal" patients. A substantial and rapid downward progression of the albumin-tagged tracer has been observed. This progression is faster than the subarachnoidal ascent toward the convexity of the brain.
