Which of the following is NOT listed as a bone densitometry technique?

• A. Central skeletal measurements
• B. Total body/body composition
• C. Pediatric assessment
• D. Ultrasound bone density

Answer: (D)

Bone densitometry relies on methods that quantify bone mineral density with imaging, most commonly DXA. Central skeletal measurements refer to scanning the central skeleton, like the spine and hip, to get BMD values. Total body/body composition uses whole-body DXA to assess overall bone density alongside fat and lean mass, giving a broader picture of bone health. Pediatric assessment involves adapting densitometry techniques for children so their bone development can be tracked accurately. Ultrasound bone density, on the other hand, doesn’t provide a direct BMD value; it uses ultrasound to infer bone properties and fracture risk rather than measuring mineral density, so it isn’t categorized as a standard bone densitometry technique.
