MRI/MRS in neuroinflammation: methodology and applications

Area of Science:

• Neuroscience
• Immunology
• Medical Imaging

Background:

• Neuroinflammation involves complex immune, endothelial, and neuronal cell interactions in the central nervous system (CNS).
• It plays a critical role in infections, trauma, autoimmune disorders, and neurodegenerative diseases.
• Understanding these interactions requires sophisticated in vivo imaging methods.

Approach:

• This review discusses various Magnetic Resonance (MR) techniques for studying neuroinflammation.
• MR methods are employed to investigate endothelial activation and blood-brain barrier (BBB) permeability.
• The review also covers MR's role in assessing immune cell trafficking and metabolic changes associated with immune activity.

Key Points:

• MR imaging provides complementary techniques to explore brain/immune interactions in vivo.
• The discussed MR approaches allow detailed study of endothelial activation, BBB integrity, and immune cell dynamics.
• Metabolic alterations linked to immune cell function can also be monitored using MR.

Conclusions:

• The complementarity of MR techniques offers a powerful approach to studying neuroinflammation.
• Assessing these complex mechanisms with MR has significant potential for clinical applications.
• This can lead to improved disease management strategies for various CNS conditions.
