Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Type 2 Diabetes with NAFLD
Patients with Type 2 Diabetes with NAFLD MR spectroscopy verified no steatosis |
Infusion of constant intravenous insulin to achieve hyperinsulinemia and concomitant infusion of glucose to maintain euglycemia (plasma glucose at 5 mM). Infusion of palmitate and VLDL-triglyceride tracer. PET/CT scans of heart and liver, both in basal period and during intervention. |
Active Comparator: Type 2 Diabetes without NAFLD
