Prevalence of sarcopenia and sarcopenic obesity in Korean adults: The Korean Sarcopenic Obesity Study (KSOS) [PDF]

, 2009
*Context:* Sarcopenic obesity (SO), a combination of excess weight and reduced muscle mass and/or strength, is suggested to be associated with an increased risk of adverse health outcomes.

Reference Data and Predictors of HR‐pQCT‐Derived Muscle Density and Its Prediction of Physical Performance

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background There is increasing awareness of a role for muscle composition in sarcopenia and cachexia. Computed tomography (CT)–based measures of muscle density (MusD) are commonly used to indicate composition, with a decrease in MusD reflecting an increase in muscle fat infiltration. The current study explored predictors of MusD acquired using

Improving decomposition image quality in dual‐energy chest radiography using two‐dimensional crisscrossed anti‐scatter grid

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background Chest radiography is a widely used medical imaging modality for diagnosing chest‐related diseases. However, anatomical structure overlap hinders accurate lesion detection. While the dual‐energy x‐ray imaging technique addresses this issue by separating soft‐tissue and bone images from an original chest radiograph, scattered ...

SPECIFIC SITES OF BONE EXPANSION DEPEND ON THE LEVEL OF VOLLEYBALL PRACTICE IN PREPUBESCENT BOYS

Biology of Sport, 2013
The purpose of this study was to investigate the effect of 18 months of high and low levels of volleyball practice on bone acquisition. 130 prepubescent boys (mean age 11.4 ± 0.7) were divided into a high-level training group (HLG), low-level training ...

Downturn in Childhood Bone Mass: A Cross‐Sectional Study Over Four Decades

JBMR Plus, 2022
Screen time and physical inactivity have increased among children. As physical activity is a determinant of bone mass, there is a concern that children today have lower bone mass than earlier.

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays

Journal of Applied Clinical Medical Physics, Volume 26, Issue 6, June 2025.
Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Determinants of bone damage: An ex-vivo study on porcine vertebrae. [PDF]

PLoS ONE, 2018
Bone's resistance to fracture depends on several factors, such as bone mass, microarchitecture, and tissue material properties. The clinical assessment of bone strength is generally performed by Dual-X Ray Photon Absorptiometry (DXA), measuring bone ...

AAPM Task Group No. 249.B—Essentials and guidelines for clinical medical physics residency training programs

Journal of Applied Clinical Medical Physics, Volume 26, Issue 6, June 2025.
Abstract The establishment of guidelines and curriculum standards for medical physics residency training is a critical component of setting expectations and competencies for the profession. Since the last publication of these standards, residency training has become integrated into the eligibility criteria for most medical physics certification bodies.
