What the trial is, and whether it could suit you
Background:
Multiple sclerosis (MS) and progressive multifocal leukoencephalopathy (PML) are disorders that affect the central nervous system (CNS). The CNS includes the brain, spinal cord, and optic nerves. Both diseases can cause muscle weakness and impair vision, speech, and coordination. Researchers are working to better understand how MS and PML affect the CNS.
Objective: To test whether an experimental radioactive tracer (minibody) can help positron emission tomography (PET) scans detect certain immune cells in the CNS of people with MS and PML.
Eligibility:
People aged 18 years and older with MS, other neuroinflammatory diseases with BBB leakage, or PML.
Design:
Participants will come to the clinic for at least 3 visits over 4 to 6 weeks.
Participants will undergo testing. They will have a physical and neurological exam. They will have blood tests and tests of their heart f

* Male or female, aged \>=18.
EXCLUSION CRITERIA:
An individual who meets any of the following criteria will be excluded from participation in this study:
* Pregnant or lactating.
* Contraindications for MRI gadolinium contrast administration or 3T MRI.
* History of, or current diagnosis with, concomitant medical or clinical conditions that would adversely affect participation in this study.
* Weighs \> 350 lb. (158 kg; weight limit for the scanner table) or is unable to fit within the MRI or PET imaging gantry.
* Severe claustrophobia unresponsive to oral anxiolytics.
* Has an alkaline phosphatase level greater than 2x ULN (unless known to have non-liver related disorder) OR AST greater than 1.5 x ULN OR ALT greater than 1.5 x ULN.
* Has a total bilirubin \>1.5X ULN, unless known to have elevated bilirubin due to nonliver related disorder or Gilbert s.
* Creatinine clearance \< 60 mL/min as estimated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)
