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 ...

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 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.

A simple equation to estimate body fat percentage in children with overweightness or obesity: a retrospective study [PDF]

PeerJ, 2017
Background Dual-energy X-ray absorptiometry (DXA) provides separate measurements of fat mass, fat-free mass and bone mass, and is a quick, accurate, and safe technique, yet one that is not readily available in routine clinical practice.

Novel lateral whole‐body dual‐energy X‐ray absorptiometry of lumbar paraspinal muscle mass: results from the SarcoSpine study

Journal of Cachexia, Sarcopenia and Muscle, 2021
Background Here, we aimed to propose novel lateral whole‐body dual‐energy X‐ray absorptiometry (lateral DXA) as a simple tool for measuring spinal muscle mass and investigate the feasibility of lateral DXA to measure lumbar paraspinal muscle (LPM) mass ...

Computed tomography-osteoabsorptiometry for assessing the density distribution of subchondral bone as a measure of long-term mechanical adaptation in individual joints [PDF]

, 1989
To estimate subchondral mineralisation patterns which represent the long-term loading history of individual joints, a method has been developed employing computed tomography (CT) which permits repeated examination of living joints.
