Cross-Calibration of GE Healthcare Lunar Prodigy and iDXA Dual-Energy X-Ray Densitometers for Bone Mineral Measurements
In long-term prospective studies, dual-energy X-ray absorptiometry (DXA) devices need to be inevitably changed. It is essential to assess whether systematic differences will exist between measurements with the new and old device. A group of female volunteers (21-72 years) underwent anteroposterior lumbar spine L2-L4 (n = 72), proximal femur (n = 72), and total body (n = 62) measurements with th...
متن کاملScan Mode Performance of Dual Energy X-ray Absorptiometry Bone Densitometer
Objective: A commercially available dual energy X-ray absorptiometry scanner normally provides more than 1 scan mode. The differences between scan modes affect scan time, received radiation dose, and quality of the scan image. A phantom study was performed to evaluate the performance of different scan modes for anteriorposterior spine scan. Patients and Methods: To measure the entrance skin exp...
متن کاملSimulated increased soft tissue thickness artefactually decreases trabecular bone score: a phantom study
BACKGROUND Trabecular bone score (TBS), which has been proposed to be used in complementary with bone mineral density (BMD) to improve the assessment of fracture risk, is negatively associated with body mass index (BMI). The effect of soft tissue, which is expected to be thicker in subjects with high BMI, on TBS was studied using three scan types: Hologic with fast array mode (Hfa), Hologic wit...
متن کاملLunar Observer Iaser Altimeter Observations for Lunar Base .- Site Selection
One of the oqtical datasets for optimal selection of future lunar lana_ng sites is local, to regional-scale topography. Lunar base site selection will require such data for hoth engineering and scientific olX,rations purposes. The Lunar Geosctence Orbiter or Lunar Obsert_or is the ideal precursory science mission from which to obtain this required information. We suggest that a simple laser alt...
متن کاملCross calibration of two dual-energy X-ray densitometers and comparison of visceral adipose tissue measurements by iDXA and MRI
OBJECTIVE Compare total percentage body fat (pfat) measurements between two densitometers and visceral adipose tissue (VAT) estimates between iDXA and magnetic resonance imaging (MRI) from the same defined abdominal region. METHODS Participants [N = 93 (50 men, 43 women), BMI: 19.1-57.6 kg/m2 ] underwent dual-energy X-ray absorptiometry (DXA) scans on two DXA systems (GE Healthcare Lunar iDXA...
