Bone densitometry is used to diagnose osteoporosis by measuring bone density. Which option best fits this modality?

• A. Computed Tomography
• B. Ultrasound
• C. Magnetic Resonance Imaging
• D. Bone Densitometry

Answer: (D)

Bone densitometry is the imaging method designed to quantify bone mineral density and diagnose osteoporosis. It typically uses dual-energy X-ray absorptiometry (DXA) to measure how much mineral is in a bone, producing a bone density value that is compared to reference norms to determine osteoporosis or fracture risk. Other modalities—CT, ultrasound, and MRI—provide anatomical detail or assess different aspects of bone health but do not routinely measure density in the standardized way used for osteoporosis diagnosis. Thus, this modality best fits the purpose.
