Official title
Three-Tracer PET Quantitation of Insulin Action in Muscle
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research is to develop a new method to study insulin action using positron emission tomography (PET). Insulin is the hormone made by your body to control the blood sugar level. We want to develop a way to image (look at) the following three things: 1) how insulin affects blood flow in skeletal muscle 2) how insulin affects glucose (sugar) transport (movement) into muscle, and 3) how insulin affects glucose metabolism (breakdown) in skeletal muscle of healthy individuals. The long term goal will be to later apply this method to the study of metabolic diseases, especially type 2 diabetes mellitus and obesity. PET imaging is a relatively non-invasive way to obtain a "metabolic picture" of body organs, and has been used successfully to study brain, heart and more recently skeletal muscle. In this research study, we will use PET with as many as four radioactive tracers (markers) to study skeletal muscle glucose transport in healthy volunteers.
