What are the main body parts assessed in DEXA?

• A. Hips, Wrists, Spine
• B. Hips, Knees, Spine
• C. Spine, Ribs, Clavicle
• D. Skull, Pelvis, Hips

Answer: (A)

DEXA assesses bone mineral density at specific sites to gauge fracture risk. The hip (proximal femur) and spine (lumbar region) are the primary sites because changes there are most predictive of major fractures. The wrists (forearm) are also commonly scanned as an additional site when spine or hip imaging isn’t suitable. So, the combination of hips, wrists, and spine matches the standard sites used in routine DEXA assessments. Other options include areas not routinely measured for bone density in DEXA, such as knees, ribs, clavicle, or skull, which aren’t standard sites for BMD evaluation.
