To evaluate 18F-AV-133 imaging of the pancreas in patients with early type 2 diabetes, late type 2 diabetes, subjects with pre-diabetes and in healthy overweight/obese control subjects. These subjects will also be evaluated for beta-cell function as measured by the insulin and C-peptide response to a challenge with intravenous arginine under basal and glucose enhanced conditions.
