title: Dynamics of cerebrospinal fluid circulation evaluated by metrizamide CT cisternography.
abstract: Cerebrospinal fluid (CSF) circulation has been analyzed by metrizamide computed tomography (CT) cisternography in 46 patients. Included were 7 patients without any clinical evidence of impaired CSF circulation, and 39 with hydrocephalus due to various causes. CT cisternography delineated the anatomical structures of the CSF pathways clearly and accurately and enabled us to analyze ventricular filling in a quantitative manner. As a result, a new, more precise CT cisternographic classification of the CSF flow patterns has been established. On the basis of the presence of ventricular reflux and stasis, extent of ventricular filling, and convexity flow of metrizamide, seven groups of flow patterns have been defined.
