Brief Summary

There are three goals for this study. One is to investigate how different emotions and exposure to cold affect blood flow in the body. The second aim is to study how insulin affects blood flow and tissue glucose uptake, and to study whether this effect is altered in obesity. Last, the study focuses on establishing the lowest dose of a PET radiotracer, oxygen-15 labelled water, that can be used in clinical studies with a new whole-body PET scanner.
