Osteoporosis has an estimated prevalence of up to 30% among post-menopausal women in Europe. Osteoporotic spine and hip fractures considerably reduce quality of life and are associated with an increased mortality. Osteoporosis can be treated using known medications, but its current early diagnosis based on bone mineral density (BMD) measurements remains insufficient and poorly correlated with fracture risk. In addition to the role of the bone mineral matrix, there is recent preliminary evidence that bone marrow fat plays a role in the pathophysiology of bone disease. MRI is the ideal tool to quantitatively measure properties of bone marrow and can be also used to simultaneously indirectly assess trabecular bone density.
Our bone and bone marrow MRI research focuses on the following directions:
