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

Relation of BMI to a dual-energy X-ray absorptiometry measure of fatness [PDF]

, 2017
Dual-energy X-ray absorptiometry (DXA) is a valid technique for measuring the fat, bone and lean (muscle, organs and water) masses of the body. We evaluated relationships of BMI (kg/m2) with independent measurements of fat and lean masses using DXA in ...

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 ...

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.

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.

The Placenta Regulates Intrauterine Fetal Growth via Exosomal PPARγ

Advanced Science, Volume 12, Issue 15, April 17, 2025.
The placenta expresses much higher levels of PPARγ than fetal adipose tissue. Trophoblastic exosomes transport PPARγ into fetal preadipocytes via fetoplacental circulation and thus regulate adipogenic genes distinct from endogenous PPARγ. Compromised placental PPARγ leads to fetal adipogenesis deficiency and intrauterine growth restriction, reversible ...
