Doctors at the National Institutes of Health (NIH) seek patients with thyroid cancer that spread outside the thyroid - to the lymph nodes, lungs or bones. The standard treatment in such situation is therapy with radioactive iodine (RAI). In this study, doctors will assess a new imaging tool - 124I PET/CT, which enables evaluation of how much iodine goes into the tumor. The study goal is to compare how much iodine goes into cancer cells after two different methods of stimulation of RAI uptake.

Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about the stages of multiple sclerosis and follow them until a person's death to understand how the physical and clinical signs of MS relate to its changes over time.

Researchers at the National Institutes of Health seek volunteers, 21-60 years old, to participate in a study researching if a gene and smoking affect drinking. All study-related tests and procedures are provided at no cost to the study participant. Compensation may be provided.
