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 ...

Preliminary Research on Dual-Energy X-Ray Phase-Contrast Imaging

, 2015
Dual-energy X-ray absorptiometry (DEXA) has been widely applied to measure bone mineral density (BMD) and soft-tissue composition of human body. However, the use of DEXA is greatly limited for low-Z materials such as soft tissues due to their weak ...

Fatty liver index associates with relative sarcopenia and GH/ IGF- 1 status in obese subjects [PDF]

, 2016
Recently the association between hepatic steatosis and sarcopenia has been described. GH/IGF-1 axis has been postulated to play a role in linking fatty liver and low muscle mass.

Body composition in patients with rheumatoid arthritis: a narrative literature review

Therapeutic Advances in Musculoskeletal Disease, 2021
There is growing interest in the alterations in body composition (BC) that accompany rheumatoid arthritis (RA). The purpose of this review is to (i) investigate how BC is currently measured in RA patients, (ii) describe alterations in body composition in

Accuracy and the influence of marrow fat on quantitative CT and dual-energy X-ray absorptiometry measurements of the femoral neck in vitro [PDF]

, 1996
Bone mineral measurements with quantitative computed tomography (QCT) and dual-energy X-ray absorptiometry (DXA) were compared with chemical analysis (ChA) to determine (1) the accuracy and (2) the influence of bone marrow fat.

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 ...

ODIASP: An Open‐Source Software for Automated SMI Determination—Application to an Inpatient Population

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background The diagnosis of malnutrition has evolved with the GLIM recommendations, which advocate for integrating phenotypic criteria, including muscle mass measurement. The GLIM framework specifically suggests using skeletal muscle index (SMI) assessed via CT scan at the third lumbar level (L3) as a first‐line approach.

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
