• A. DEXA
• B. EKG
• C. Ultrasound therapy
• D. Angiography

Answer: (A)

Radiologists oversee a broad range of diagnostic imaging, including tests that measure density in bones. Bone density testing is done to assess osteoporosis risk and uses a specific imaging modality called DEXA (dual-energy X-ray absorptiometry). It provides a quantitative measure of bone mineral density, typically at the spine and hip, making it the standard bone density test to complement the other radiologic and nuclear medicine studies listed (CT, PET, MRI, ultrasound). The other options don’t assess bone density: an EKG records heart electrical activity, ultrasound therapy is a treatment rather than a diagnostic imaging test, and angiography images blood vessels rather than bone density.
