Vertebral bone marrow glucose uptake is inversely associated with bone marrow fat in diabetic and healthy pigs: [(18)F]FDG-PET and MRI study.

Objectives: Diabetes induces osteoporosis and during osteoporosis, vertebral bone marrow (VBM) adipose tissue amount increases. The association between this adiposity and bone marrow metabolism is unclear. Here, we compared VBM glucose metabolism and fat content in healthy and diabetic pigs, in vivo, using positron emission tomography (PET), in-phase and out-of-phase magnetic resonance imaging and magnetic resonance proton spectroscopy ((1)H MR spectroscopy).
