Bone geometry, structure, and mineral distribution using dual energy x-ray absorptiometry (DXA).

Year: 1993

Type: article

Abstract: Dual energy x-ray absorptiometry (DXA) is currently the most widely used method of analyzing regional and whole body changes in bone mineral content (BMC) and areal (g/cm2) bone mineral density (BMD). However, BMC and BMD do not provide direct measures of long bone geometry, structure, or strength, nor do regional measurements detect localized changes in other regions of the same bone. The capabilities of DXA can be enhanced significantly by special processing of pixel BMC data which yields cross-sectional geometric and structural information. We have extended this method of analysis in order to develop non-uniform structural beam models of long bones.
