Reference Methods for Measuring Skeletal Muscle Mass: A Critical Perspective. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Skeletal muscle (SM) is an integral organ component in the pathophysiology of many acute and chronic diseases. But is there a ‘gold’ standard or accepted reference method for quantifying the amount and composition of human SM mass? Exploring that question led us to recognize the existence of a SM measurement paradigm that divides methods into ...

Effects of Nandrolone Decanoate on Muscle Strength, Body Composition and Bone Density: A Systematic Review and Meta-Analysis. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Background Despite ongoing interest in anabolic therapies for sarcopenia and cachexia, pharmacological interventions are being developed to counteract age‐ and condition‐related losses of muscle mass and strength. This systematic review and meta‐analysis evaluated the effect of nandrolone decanoate on lean soft tissue (LST), fat mass, handgrip

Evaluation of Skinfolds Based Predictive Equations for Estimating Body Fat Percentage in Older Adults: A Comparison Using Digital Adipometer (Lipowise) and Dual-Energy X-Ray Absorptiometry (DXA). [PDF]

Clin Obes
ABSTRACT Accurate assessment of body fat percentage (%BF) is essential for predicting health risks in older adults, as age‐related changes affect fat distribution and measurement accuracy. While dual‐energy x‐ray absorptiometry (DXA) is a standard reference, it is costly and less accessible.

Bone strain index reproducibility and soft tissue thickness influence: a dual x-ray photon absorptiometry phantom study

European Radiology Experimental, 2019
Background Bone strain index (BSI) is a tool measuring bone strain, derived from dual x-ray photon absorptiometry. It is able to characterise an aspect of bone quality that, joined to the quantity and quality parameters of bone mineral density (BMD) and ...

Photon-Counting CT Material Decomposition in Bone Imaging

Journal of Imaging, 2023
The accurate screening of osteoporosis is important for identifying persons at risk. The diagnosis of bone conditions using dual X-ray absorptiometry is limited to extracting areal bone mineral density (BMD) and fails to provide any structural ...

Primary Hyperparathyroidism in Adults: Recent Developments in Diagnosis and Management. [PDF]

Med J Aust
ABSTRACT Primary hyperparathyroidism has a prevalence of around 1% in the general population. Diagnosis requires biochemical testing of serum (for calcium and parathyroid hormone) and urine (for calcium excretion), as well as wider screening for complications including osteoporosis, renal disease, abdominal symptoms and neuropsychiatric disturbance.

Body composition measures assessed by bioelectrical impedance analysis and dual-energy X-ray absorptiometry in a sample of Brazilian adults and older adults [PDF]

Frontiers in Nutrition
IntroductionBioelectrical impedance analysis (BIA) is a common technique for assessing body composition in clinical and epidemiological settings. However, its accuracy is limited compared to reference methods such as dual-energy X-ray absorptiometry (DXA)

Dual-energy X-ray absorptiometry of the forearm: Reproducibility and correlation with single-photon absorptiometry

Journal of Bone and Mineral Research, 1992
Abstract Although single-photon absorptiometry (SPA) has been the predominant tool used to assess bone mineral density (BMD) in the forearm, the development of dual-energy x-ray absorptiometry (DEXA) provides the benefits of greater source stability, reduced scanning time, and improved image resolution compared to SPA.

Comparison of Two DXA Systems, Hologic Horizon W and GE Lunar Prodigy, for Assessing Body Composition in Healthy Korean Adults [PDF]

Endocrinology and Metabolism, 2021
Background Dual-energy X-ray absorptiometry (DXA) is the most widely used method for evaluating muscle masses. The aim of this study was to investigate the agreement between muscle mass values assessed by two different DXA systems.

Characteristics Associated with Bone Loss after Spinal Cord Injury: Implications for Hip Region Vulnerability [PDF]

Endocrinology and Metabolism, 2023
Background In individuals with spinal cord injury (SCI), bone loss progresses rapidly to the area below the level of injury, leading to an increased risk of fracture.
