Bone microarchitecture, density, and strength assessment in automotive trauma patients using HR-pQCT: a pilot study.

OBJECTIVE Automotive trauma patients enrolled in the Crash Injury Research and Engineering Network (CIREN) typically undergo computed tomography (CT) imaging as part of emergency care. HR-pQCT is a noninvasive imaging technique that enables assessment of bone microarchitecture at the peripheral sites. CT and HR-pQCT ca...

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 spaceflight using quantitative magnetic reson...

Leg muscle assessment by HR-pQCT and DXA: associations between imaging measures and muscle function in adults with obesity—a pilot study

Abstract DXA and 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 area (CSA) and density vs DXA-derived lean mass, and explored associations with muscle strength, power, and physical performance in adults...

Multi-ethnic evaluation and calibration of 3D-DXA femoral shape, density and FEA strength

This is the first study to independently evaluate 3D-DXAs on multi-ethnic data across a wide age, including previously unstudied cohorts, and more than doubling the number of subjects used in prior validation works, providing detailed insights into the accuracy and limitations of DXA-based 3D reconstruction methods.

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)

Given that failure load is a strong predictor of fracture risk, future studies should investigate whether interventions that target muscle size may impact fracture risk in older adults.
