Aims of this study were: 1) to correlate T2, T2*, ADC and Gi of the calcanei spongy-bone measured in healthy, osteopenic and osteoporotic women with their correspondent bone-marrow fat-content, assessed by 1H-MRS and their T-score 2) to assess the ability of each MR parameter to predict the osteopenic and/or osteoporotic status of bone; 3) to identify the MR-parameter which better predicts the bone fracture risk. Our results show the great potentiality of ADC and T2* in combination with 1H-spectroscopy in the diagnosis of osteoporosis. This study highlights that the best parameter to assess the bone status is skeletal-site-dependent.
