Bone is composed of two tissues: a mineralized cortical and trabecular bone component and a fatty and hematopoietic marrow component. Osteoporosis is a disease of weak bone and increased fracture risk due to low bone mass. Recent studies pointed link between bone marrow adipose tissue (bMAT) and osteoporosis notably in term of bMAT composition. Chemical Shift- Encoded MRI (CSE-MRI) allows detection of fat amount and fat composition. Our aim was to assess long term repeatability of CSE-MRI in proximal femur bMAT.
