What is the general term for measuring bone mineral content and density at skeletal sites?

• A. Osteoporosis screening
• B. Radiography
• C. Osteogenesis assessment
• D. Bone densitometry

Answer: (D)

Measuring bone mineral content and density at specific skeletal sites is bone densitometry. This term specifically refers to the quantitative assessment of how much mineral is in bone (bone mineral content) and how dense the bone is (bone mineral density) at regions such as the spine or hip. The most common method is dual-energy X-ray absorptiometry (DXA), which provides BMD in g/cm² and helps generate T-scores or Z-scores to diagnose osteoporosis and estimate fracture risk. This focused measurement distinguishes it from broader imaging or screening terms: osteoporosis screening encompasses risk assessment and may include densitometry but isn’t itself a measurement technique, radiography is general imaging without precise mineral quantification, and osteogenesis assessment isn’t a standard term for this purpose. In short, bone densitometry is the standard, specific way to quantify bone mineral content and density at skeletal sites.
