Body position influence on cerebrospinal fluid volume redistribution inside the cranial and spinal CSF compartments.

ABSTRACT:

Introduction

It is generally accepted that during body position changes from horizontal to vertical there is a short-lasting shift of a certain CSF volume from the cranium into the hydrostatically lower parts of the spinal space, which leads to transitory CSF pressure decrease to negative values.

Methods

In order to test this, we performed MRI volumetry of cranial and spinal part of the CSF space in healthy volunteers of both genders (n = 22) in three different body positions [horizontal (H); elevated head and upper body (H-UP) under an angle about 30° from the base; elevated lower body (B-UP) under an angle about 30° from the base].

Results

Volumes of brain and spinal cord tissue did not change during body position changes. Significant CSF volume (ml) changes
