Having certain medical conditions, such as arthritis or liver disease, can have a negative effect on bone health. Bone densitometry is a test that determines whether a person is experiencing a decrease in bone density. From there, a doctor can determine the underlying reason for the change. Here is a guide to what a bone density test is and what to expect during the procedure.

What Is a Bone Density Test?

There are numerous minerals in bone tissue, including calcium, phosphorus, and magnesium. Bones also store minerals for release into the bloodstream when needed. 

Hormone levels, diet, medical conditions, sex, and age are a few factors that affect bone density. A bone density test is an X-ray, dual-energy X-ray absorptiometry (DXA), or CT scan used to measure the mineral content of a segment of bone in the hip, spine, or forearm.  

What Is the Test Used For?

When mineral content decreases, bones become brittle and could break easily. You might also experience posture changes and back problems. Osteoporosis is a common bone disease that a doctor can diagnose through testing. Women over the age of 65 should have bone density testing, as they are at higher risk of developing osteoporosis. 

Your doctor might also recommend the screening if you have a family history of osteoporosis or a risk factor, such as rheumatoid arthritis. Based on the results, your doctor might prescribe calcium and vitamin D supplements or discuss other options to increase mineral levels.  

What Should You Expect?

You can wear your normal clothes to the appointment, which might take place at your doctor's office or an imaging facility. Just avoid garments with metal details, as the metal could compromise the scan. 

With a central DXA test, you will lay on a table while an X-ray machine scans bones in your spine, torso, or hip. During a peripheral DXA test, bones in the forearm, fingers, wrist, or heel are tested.

If you've experienced joint pain, back problems, recent fractures, or additional cause for concern, contact the staff at Tri Rivers Musculoskeletal Centers in Wexford, PA. The rheumatologist will perform bone density testing and then discuss next steps to take to manage your arthritis or osteoporosis.
