Room: Marquis Ballroom 1-4

Dual Energy X-Ray Absorptiometry (DXA)is a radiologic technique used to evaluate the composition of tissues in the body. Its most widely known application is in bone densitometry, but it is also used to determine whole-body composition (bone, lean, and fat). The fundamental science behind DXA is similar to that of dual-energy imaging, but with variations important to its uses as a quantitative modality rather than an imaging modality.

This session will explore the variations in DXA technology from its roots in Dual Photon Absorptiometry to the clinical scanners in use today, and the kinds of QA testing typically performed on DXA scanners.

Learning Objectives:
1. Understand the fundamental science behind DXA
2. Understand the variations in technology between models of DXA scanners
3. Understand the kinds of QA testing done on DXA scanners
