Question

Dexa scan: -1-2.5: ? >-2.5: ?

a. Normal bone density, Osteoporosis
b. Osteopenia, Normal bone density
c. Osteoporosis, Osteopenia
d. Normal bone density, Osteopenia

Answer 1

A DEXA scan result with a T-score between -1 and -2.5 indicates Osteopenia, while a T-score less than -2.5 indicates Osteoporosis. Hence, option d (Normal bone density, Osteopenia) is the correct interpretation of the results.

Step-by-step explanation:

The question pertains to the interpretation of a Dual-energy X-ray absorptiometry (DEXA) scan in the diagnosis of bone density conditions. According to the World Health Organization (WHO), a DEXA scan result with a T-score between -1 and -2.5 indicates Osteopenia, which is a condition of lower than normal bone density but not low enough to be classified as osteoporosis. A DEXA scan result with a T-score less than -2.5 indicates Osteoporosis, which is a severe loss of bone density leading to bones that are weak and more likely to fracture.

Therefore, the correct answer to the question is: Dexa scan: -1 to -2.5 indicates Osteopenia (>-2.5 indicates Normal bone density), and a score less than -2.5 indicates Osteoporosis.
