#7
Which medical imaging technique is commonly used to diagnose osteoporosis?
X-ray absorptiometry (DEXA)
ExplanationX-ray absorptiometry (DEXA) is a common medical imaging technique for diagnosing osteoporosis by measuring bone density.
#8
What is the T-score used for in the context of osteoporosis diagnosis?
Assessing bone density compared to a young adult reference
