Marrow proton density fat fraction (PDFF) and R2* at the lumbar spine in postmenopausal females of widely varying bone density were simultaneously measured with a 3D Fat Analysis & Calculation Technique (FACT) Sequence at 3.0T. Discrimination of osteopenia and osteoporosis can be improved with a combination of the PDFF and R2*.
