Abstract:
Dual-energy x-ray absorptiometry (DXA) has become the most commonly employed technique worldwide for assessment of bone mineral content in adults and children. DXA interpretation in children is more complex because bone dimensions are highly dynamic. Pediatric use of DXA can be used to identify risk of adult osteoporosis. This technology and the increasing knowledge of the genetics, mutations, and mutagens associated with the development of osteoporosis are tools to identify the phenotypes and genotypes in children at risk for osteoporosis later in life, and to design appropriate early interventions for this condition. This paper gives a brief overview of how DXA works, calibration issues, efficacy, safety, and test interpretation.

Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
