Brief Summary
University of Pittsburgh Medical Center (UPMC) diabetes research physicians are studying the action in muscle tissue of "inhaled" insulin (Exubera®) and "infused" (intravenous or IV) insulin on blood sugar control in people with type 1 diabetes. Type 1 diabetics often take 2-4 shots of insulin every day. Exubera may offer an alternative to these insulin injections.

Outcome Measures
Primary Outcomes (1)
To perform positron emission tomography (PET) imaging of [18F]-fluoro-deoxy-glucose (FDG) uptake by muscle, following administration of a single dose of inhaled compared to infused insulin in volunteers with type 1 diabetes
Secondary Outcomes (1)
To determine overnight rates of glucose production and plasma glucose after a single pre-dinner dose of inhaled compared to IV infused insulin in volunteers with type 1 diabetes
