Quantitative MRI changes in neck muscle size and composition following long‐duration spaceflight

Abstract Long‐duration spaceflight poses several challenges to human health, including muscle loss and fat deposition. To mitigate these effects, exercise countermeasures are prescribed. This study aimed to measure neck muscle size and composition changes with long‐duration space...

Leg Muscle Assessment by HR-pQCT and DXA: Associations Between Imaging Measures and Muscle Function in Adults with Obesity – A Pilot Study

Abstract Dual energy X-ray absorptiometry (DXA) and high-resolution peripheral quantitative computed tomography (HR-pQCT) are used for bone assessment but also image adjacent soft tissue. This pilot study examined association between HR-pQCT-measured leg muscle cross-sectional ar...

Greater D3-Creatine Muscle Mass and MRI Thigh Muscle Volume are Associated with Higher Bone Strength in Older Adults: Exploratory Findings in The Study of Muscle, Mobility and Aging (SOMMA)

Abstract Low bone mineral density (BMD) and impaired bone strength are established risk factors for fractures in older adults. Decreased muscle size also contributes to fracture risk, however, the relationship between muscle size and bone density, microarchitecture, and strength...
