A bone density scanner, also known as a dual-energy X-ray absorptiometry (DXA) scan machine, is a specialized type of X-ray machine that measures the density of bones. The scanner works by sending two low-dose X-ray beams through the bones being examined, and then measuring the amount ...
This chapter presents several noninvasive imaging techniques for measuring bone properties in children and adolescents. Dual-energy x-ray absorptiometry (DXA) is the most widely used but has several major limitations because it depends on two-dimensional projections. Quantitative computed tomography (QCT...
Fig. 2. DXA scanning device. Bone density measured by DXA is an areal density (g/cm2) rather than a volumetric density (g/cm3). The BMD is the bone mineral content (in grams) per unit area (cm2). The DXA scans are analyzed to generate measures of projected bone area, bone mineral...
Bone density or bone mineral density is the amount of bone mineral in the bone tissue. Bone density measurements are used in clinical medicine as an indicator of osteoporosis, a disease that makes your bones weak, and increases the risk of fractures. It can also indicate your response to trea...
Bone densitometry systems are required to fulfill various roles. For example,Ultrasound is used to measure bone density during pregnancy, and DXA is used for a detailed examination after childbirth. FUJIFILM's bone densitometry system will always support women regardless of their life stages....
The most commonly used method of measuring bone mineral density (BMD) is dual-energy X-ray absorptiometry (DXA). In this chapter, the basic principles of bone densitometry and its clinical applications in the management of pediatric patients affected by IBD are described. Bone modeling and ...

Dual x-ray absorptiometry (DXA) is the most widely used measurement for the assessment of bone mass in osteoporosis. In clinical measurement, bone width can affect bone mineral parameters. The purpose of this study was to examine the dependence of bone mineral pa-rameters on bone width. In ...
Frequently, BMC values are divided by the projected area of the bone analyzed and referred to as bone mineral density or BMD (g/cm2). DXA has been used for bone measurements in the whole body, the lumbar spine, the proximal femur, the forearm and the hand, and, in all sites, DXA ...
