Chronic Fatigue Syndrome, Fibromyalgia, Healthy, Multiple Sclerosis
Conditions
Brief 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.
Interventions
DRUG[Zr-89]Oxine-labeled leukocytes PET/MRI
All study participants will undergo an investigational imaging study using autologous \[Zr-89\]-labeled leukocytes and brain PET/MRI. Participants will undergo a venous blood draw, and the leukocytes in the blood sample will be isolated for labeling using \[Zr-89\]oxine. The labeled leukocytes (7.4- 18.5 megabecquerel (MBq), 200-500 uCi) will be re-injected into the participant followed by brain PET/MRI at 24-48 hours after injection. Participants will be asked to have a second brain imaging study 3-6 days after this injection, but this second imaging study is optional.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Regional brain distribution of radiolabeled white blood cells | 3 years | Descriptive statistics (means and standard deviations) of standardized uptake values (SUVs) will be presented for the patient groups and healthy controls in the following regions: whole brain, gray matter, white matter, atlas-based regions of interest, and lesions (MS patients only). Normality of the SUV distribution will be tested using Shapiro-Wilk tests, and the data will be transformed to normal distribution if necessary. |
