Phase-Contrast-Cine MRI: a non-invasive qualitative approach to the study of various diseases of the Central Nervous System

Abstract

The introduction of velocity-sensitive sequences, such as those based on the phase-contrast technique, has recently
established a lure for the evaluation of the dynamics of CSF in MRI because it is the only non-invasive method for
the study of the CSF flow.
These sequences add to the classic anatomical study of brain, a qualitative functional analysis of his cerebrospinal
fluid system studied with sequences acquired in the sagittal plane, maintaining high spatial and temporal resolution
despite the small size of the analyzed section and the low speed of the circulating liquor.
The aim of this paper is to illustrate the importance of using amplitude and phase (Phase Contrast) images in CineRM, in healthy subjects and in patients with intra-cranial and cervical district diseases.
