Measurement of bone quality in growing male rats using dual energy x-ray absorptiometry and bone ash content : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Animal Science at Massey University, Palmerston North, New Zealand [PDF]

, 2001
Growing male rats have been considered and used as a model for bone growth and prevention of osteoporosis because of their high bone turnover and demand for calcium. Dual Energy X-ray Absorptiometry (DEXA) is a useful tool for identifying minimal changes

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 ...

The disparity of measuring bone mineral content using bioimpedance and dual-energy absorptiometry in the context of hyperparathyroidism

Brazilian Journal of Nephrology, 2020
Introduction: Body composition is critical for the evaluation of patients with Chronic Kidney Disease (CKD) and can be obtained from either multifrequency bioelectrical impedance analysis (BIA) or dual-energy absorptiometry (DXA).

The mandibular angle in osteoporotic men [PDF]

, 2011
Objectives: Osteoporosis induces the reduction of bone mass and screening for low bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) has been the current gold standard test to determine osteoporosis.

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.

Comparison of brain serotonin transporter using [I-123]-ADAM between obese and non-obese young adults without an eating disorder. [PDF]

PLoS ONE, 2017
Cerebral serotonin metabolism has an important but controversial role in obesity. However, it is not given enough attention in morbidly obese young adults.

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.

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.

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 ...
