Is a bone scan and bone density test the same?
DXA scans and whole-body bone scans are similar tests. Both tests involve scanning your bones, but providers use them to check different aspects of your bone health. DXA scans are special X-rays that measure your bone density to screen you for osteoporosis and other conditions that weaken your bones.
What are the two types of bone density tests?
A bone density test is used to measure bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
What is the best imaging for osteoporosis?
Dual x-ray absorptiometry is currently the state-of-the-art technique to measure bone mineral density and to diagnose osteoporosis according to the World Health Organization guidelines.
Why would a doctor order a bone density scan?
A bone density test measures how strong your bones are. The test will tell you if you have osteoporosis (weak bones), and it can help you understand your risk of breaking a bone in the future.

For example, a 2021 study found that older adults living in a care facility who experienced a hip fracture had a 25% death rate after 3 months.
Does Medicare pay for a bone density scan?

Which fruit is best for bones?
Figs contain minerals and vitamins that are essential for bone health. One cup of stewed figs has about 180 milligrams of calcium, plus some vitamins C and vitamin K.
