Entire-body PET Scans for Multiple Sclerosis

To collect exploratory data using the most recent PET-CT scanners with their increased detection sensitivity and spatial resolution for the evaluation of F18-florbetapir radiopharmaceutical uptake in the nervous system of the entire body with special attention to correlation of radiotracer activity levels in the myelinated, demyelinated, or remyelinated white matter of multiple sclerosis (MS) patients compared to normal healthy subjects. The pilot study will be conducted on 20 participants as a clinical research trial of PET amyloid and myelin imaging with the primary objective of identifying possible differences in F18-florbetapir radiotracer activity for MS patients compared to normal healthy subjects, and the secondary objective of monitoring psychological health of those participants who elect to be informed of imaging results and who complete a panel of psychometric scales before and after imaging results disclosure.

Inclusion criteria

• Multiple sclerosis (MS) patients diagnosed by a credentialed neurologist experienced with care of multiple sclerosis patients.
• Normal healthy subjects.
• Willing and able to lie motionless on the PET-CT scanner bed for at least 10 minutes and up to 20 minutes for the duration of the PET-CT medical imaging scan.

Exclusion criteria

• Any additional complicating medical illness other than MS including any other neuropsychiatric illness unrelated to MS diagnosed prior to the onset of initial symptoms of MS.
• Pregnancy or breast feeding.
• Diabetes or other metabolic-endocrine disorders.
• Any known concomitant acute infection.
