Tracking Peripheral Immune Cell Infiltration of the Brain in Central Inflammatory Disorders Using [Zr-89]Oxinate-4-labeled Leukocytes.

Summary

This study will use brain Positron Emission Tomography/ Magnetic Resonance Imaging (PET/MRI) and an investigational radioactive drug called \[Zr-89\]oxine to track the location of white blood cells (also called leukocytes) in the body. PET/MRI will be used to visualize labeled white blood cells and determine if they enter the central nervous system in conditions associated with brain inflammation (also called neuroinflammation). By better understanding the role of neuroinflammation in fibromyalgia, chronic fatigue syndrome, and multiple sclerosis, the investigator hopes to be able to better diagnose and treat patients in the future.
