A cerebrospinal fluid (CSF) flow MRI is a specialized type of MRI scan used to visualize the flow of cerebrospinal fluid within the brain and spinal canal. In a CSF flow MRI, the goal is to assess the dynamics of this fluid to ensure it is moving properly throughout the brain and spinal column.

2024年8月28日 · CSF flow studies are performed using a variety of MRI techniques and are able to qualitatively assess and quantify pulsatile CSF flow. The most common technique used is time-resolved 2D phase-contrast MRI with velocity encoding.

PC-MRI is widely used to evaluate CSF hydrodynamics in normal pressure hydrocephalus (NPH), Chiari type I malformations (CMI), syringomyelia, and after neurosurgical procedures. In NPH precisely performed PC-MRI provides reliable clinical information useful for differential diagnosis and selection of patients benefiting from surgical operation.

In this pictorial review, we emphasise phase-contrast (PC) MRI technique, CSF physiology and cerebrospinal space anatomy, congenital and acquired disorders that can alter the cerebrospinal fluid dynamics, and the use of PC MRI in the assessment of various central nervous system (CNS) abnormalities.

2017年1月31日 · Phase-contrast MRI is a noninvasive method of measuring CSF flow dynamics. One of the most common indications for phase-contrast MRI is the assessment of patients with suspected normal-pressure hydrocephalus (NPH) and its differentiation from other disorders with a similar MRI appearance of ventricular enlargement [1 – 4].

Cerebrospinal fluid (CSF) flow MRI is used to assess pulsatile CSF flow both qualitatively and quantitatively. Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [1]

hase-contrast MRI is a noninva- P sive method of measuring CSF flow dynamics. One of the most common indications for phase-contrast MRI is the assessment of patients with suspected normal-pressure hydrocephalus (NPH) and its differentiation from other disor-ders with a similar MRI appearance of ventric-ular enlargement [1–4].

2019年1月28日 · The advent of MR technology with the emergence of new pulse sequences allowed better understanding of CSF flow dynamics. In this pictorial review, we aim to conduct a comprehensive review of the MR protocol used to study CSF flow disorders and to discuss the utility of each pulse sequence in the adopted protocol.

2016年4月1日 · This article provides an overview of magnetic resonance imaging (MRI) techniques used to assess cerebrospinal fluid (CSF) movement in the central nervous system (CNS), including Phase-Contrast (PC), Time-Spatial Labeling Inversion Pulse, and simultaneous multi slice echo planar phase contrast imaging.

2019年5月13日 · PC-MRI is widely used to evaluate CSF hydrodynamics in normal pressure hydrocephalus (NPH), Chiari type I malformations (CMI), syringomyelia, and after neurosurgical procedures. In...
