Uptake of [11C]5-HTP in the human pancreas is not dependent on perfusion. Uptake of [11C]5-HTP in the human pancreas is not dependent on perfusion. A: Correlation between pancreatic size and % ID in all individuals. Pancreatic uptake of [11C]5-HTP as % ID completely separates between the TID and HV groups, whereas there is a substantial overlap in pancreatic volume despite the difference at group level. B: There is no correlation between the perfusion of pancreas and the uptake of [11C]5-HTP as measured by % ID. Olof Eriksson et al. Diabetes 2014;63:3428-3437 ©2014 by American Diabetes Association
