Dual-energy X-ray absorptiometry: fat estimation errors due to variation in soft tissue hydration.

, 1998
Dual-energy X-ray absorptiometry (DXA) is rapidly gaining acceptance as a reference method for analyzing body composition. An important and unresolved concern is whether and to what extent variation in soft tissue hydration causes errors in DXA fat ...

Comparison of total-body measurements by dual-energy x-ray absorptiometry and dual-photon absorptiometry

Journal of Bone and Mineral Research, 1991
Abstract Both dual-photon absorptiometry (DPA) using 153Gd and dual-energy x-ray absorptiometry (DEXA) can be used for measurement of bone mineral content (BMC) and bone mineral density (BMD) of the total skeleton and its seven major regions.

Comparison of Total-Body Calcium with Radiographic and Photon Absorptiometry Measurement of Appendicular Bone Mineral Content [PDF]

, 1978
Two groups of investigators utilized three techniques for evaluating bone mineral mass. In one institution, total-body calcium by total body neutron activation analysis, and bone mineral content of the radius by photon absorptiometry were measured ...

A proposal for individualized administration of energy and protein in the critically ill with obesity

Nutrition in Clinical Practice, EarlyView.
Abstract The increasing prevalence of obesity has transformed intensive care and nutritional therapy of patients with obesity from a specialized problem to standard care. The dilemma in providing nutrition to critically ill patients with obesity is that current and historical nutritional guideline recommendations are based on expert opinion, are ...

Severe malnutrition and persistent myopenia despite weight recovery in newly diagnosed stricturing Crohn's disease: A case report

Nutrition in Clinical Practice, EarlyView.
Abstract Protein‐energy malnutrition is a common complication in Crohn's disease (CD). In addition to weight loss, patients may develop significant alterations in body composition, including skeletal muscle depletion, which can negatively affect clinical outcomes and quality of life.

Seeing Through the Density: A Case of Misleading BMD Results on bone densitometry

Journal of the Pakistan Medical Association
Bone mineral densitometry (BMD) using dual-energy X-ray absorptiometry (DXA) is widely recognized as the standard method for evaluating bone density. DXA produces attenuation maps that aid in measuring BMD. Non-relevant findings are commonly observed in

Validity and agreement of bioelectrical impedance equations against dual energy X‐ray absorptiometry for muscle mass assessment in patients on hemodialysis: A cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Low muscle mass is common in patients on hemodialysis (HD), and bioelectrical impedance analysis (BIA) predictive equations have been proposed as an alternative for estimating muscle mass. This study aimed to analyze the validity and agreement of different BIA‐based prediction equations against dual energy X‐ray absorptiometry (DXA)
