A Repeatability Study of Fatty Acid Uptake Using PET/MR Imaging in Patients With T2DM and Non-diabetic Control Subjects

"One arm: Subjects are studied under two consecutive conditions, after overnight fasting and after a liquid meal ingestion. During each condition they are examined for fatty acid uptake in subcutaneous fat and skeletal muscle by FTHA(\[18F\]-FTHA) PET/MRI as well as adipose and skeletal muscle blood perfusion by radioactive water(\[15O\]-H2O ) PET/MRI. This was done at two occasions, 2-14 days apart, to assess repeatability of the measurements.~Assigned interventions:~\[18F\]-FTHA tracer injections \[15O\]-H2O tracer injections~PET/MRI imaging~Overnight fasting Liquid meal ingestion"
