Calculated Parameters for Assessing the Interaction of Fluids in the Central Nervous System According to Radiation Introscopy (Part I)

Abstract

The aim of this literature review is to consider the range of different integral characteristics and indices, by which it can be possible to evaluate impaired hemodynamics and cerebrospinal fluid dynamics in the central nervous system according to radiation introscopy, including ultrasound and phase-contrast magnetic resonance imaging. Consideration is given to various volume-velocity and temporal parameters and the possibility of using the described characteristics to study joint blood and cerebrospinal fluid flows. Emphasis is laid on the analysis of the information provided by each of the indices and by the possibility of its clinical application. This expanded study of the interaction of fluids in the central nervous system will be able to give a better insight into the mechanisms involved in maintaining homeostasis in the brain.
