Osteoporosis (OP) is a disease associated with low bone mass and deterioration of bone microarchitecture leading to bone fragility and increased fracture risk, especially in the proximal femur. Therefore, we have developed a chemical-shift encoded acquisition performed with a spiral k-space sampling to acquire ultrashort echo-time and longer echo time in the echo train. This study aims to determine if uTE acquisition can be performed for fat/water separation and if additional information can be provided through cortical bone imaging.
