Cerebrospinal fluid flow imaging by using phase-contrast MR technique.

Area of Science:

• Neuroimaging
• Fluid dynamics
• Neurology

Background:

• Cerebrospinal fluid (CSF) spaces, including ventricles and subarachnoid spaces, are crucial for central nervous system homeostasis.
• CSF motion results from production and cardiac pulsations, vital for understanding neurological function.
• Disorders like hydrocephalus and Chiari malformation significantly alter CSF dynamics.

Purpose of the Study:

• To review the phase-contrast (PC) MRI technique for assessing CSF dynamics.
• To describe CSF physiology and anatomy of cerebrospinal spaces.
• To illustrate congenital and acquired disorders affecting CSF dynamics and their assessment using PC MRI.

Main Methods:

• Detailed explanation of the phase-contrast (PC) MRI technique.
• Review of normal CSF physiology and anatomy.
• Categorization and illustration of various CNS disorders impacting CSF flow.

Main Results:

• PC MRI is a valuable tool for visualizing and quantifying CSF motion.
• Abnormalities in CSF dynamics are associated with specific neurological conditions.
• PC MRI aids in the diagnosis and assessment of diverse central nervous system abnormalities.

Conclusions:

• Phase-contrast MRI is essential for evaluating cerebrospinal fluid dynamics.
• Understanding CSF flow is critical for diagnosing and managing various neurological disorders.
• This review highlights the utility of PC MRI in assessing central nervous system abnormalities related to CSF.
