Dual-energy X-ray Absorptiometry

Journal of Clinical Densitometry, 2017
Bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) is the most commonly used method to assess fracture risk. DXA utilizes two different energy X-rays to calculate BMD and, by comparison to a young normative database, the T-score.

Current role for bone absorptiometry

Joint Bone Spine, 2017
Bone mineral density (BMD) measurement using dual-energy X-ray absorptiometry (DXA) is a key contributor to the management of bone fragility syndromes, most notably postmenopausal osteoporosis. Experimental studies of bone biomechanics have established that an accurate marker for mechanical strength is areal BMD (aBMD, g/cm2). Areal BMD contributes 70%

Assessing underlying bone quality in spine surgery patients: A narrative review of dual-energy X-ray absorptiometry (DXA) and alternatives.

The spine journal, 2020
Poor bone quality and low bone mineral density (BMD) have been previously tied to higher rates of post-operative mechanical complications in patients undergoing spinal fusion.

Roentgen video-absorptiometry

Physics in Medicine & Biology, 1974
Discusses the feasibility of performing absorptiometric measurements using a televised image-intensified fluoroscopic system. The system consists of an X-ray generator, image intensifier, TV camera and A/D convertor under computer control for digitizing the video signals.
