Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Healthy Control Group

Subjects without inflammatory-demyelinating diseases of the central nervous system

Group Type EXPERIMENTAL

C-11 ER176 Radiotracer

Intervention Type DRUG

Administered at a single time IV prior to the PET imaging. The injected dose of C-11 ER176 will be 518 MBq (14 mCi) (range 370-666 MBq; 10-18 mCi).

C11 Pittsburgh Compound B

Intervention Type DRUG

Administered at a single time IV prior to the PET imaging. The injected dose of C-11 PiB will be 555 MBq (range 370 - 629 MBq).

PET/CT scan

Intervention Type DIAGNOSTIC_TEST

Imaging of entire brain

MRI

Intervention Type DIAGNOSTIC_TEST

Magnetic Resonance Imaging of the Brain

Multiple Sclerosis Group

Subjects with current diagnosis of Multiple Sclerosis or an InflammatoryDemyelinating Disease of the Central Nervous System will have a PET/CT scan with radiotracer drug C-11 PIB \& C-11 ER176

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Meet the requirements for one of the case or control groups.
* MS patients undergoing neurologic evaluation procedures as part of Understanding Sex Differences in Multiple Sclerosis Spectrum of Demyelinating Disorders (IRB# 19-002807) Study or the Mayo Clinic Neurology Multiple Sclerosis Clinic.
* Control participants without inflammatory-demyelinating diseases of the central nervous system
* Capacity to sign consent.

Exclusion Criteria

* Participants unable to lie down without moving for 20 minutes.
* Women who are pregnant or cannot stop breast feeding for 24 hours.
* For all patients and controls, any acute glucocorticoid (e.g., IV methylprednisolone or PO prednisolone) use within 2 weeks is an exclusion to limit medication interaction but preserve possible chronic systemic inflammation interaction with microglia activation metrics. Chronic disease modifying treatments in MS are allowed as these medications are not known to impact microglia activation.
* Standard safety exclusionary criteria for MRI such as metallic foreign bodies, pacemaker, etc., since the quantitative PET data analysis is based on anatomic criteria that are established uniquely for each subject by registration to his/her MRI.
