What Does This Test Measure?

This test specifically evaluates the mineral content in your femoral region, which includes parts of the proximal femur (near the hip joint). It measures bone density in this area, often used to identify issues like osteoporosis or other bone-related conditions.

Why Might Your Doctor Order This Test?

Your doctor may recommend this test if you have symptoms like bone pain, a history of fractures, or if you’re at higher risk for osteoporosis. It’s also used for monitoring bone health in conditions like rheumatoid arthritis or after treatments that affect bone density.

How Is the Test Performed?

You’ll lie on a table while a small X-ray device moves over your lower body. The scan takes just a few minutes and is painless. You’ll wear a gown and remove any metal objects, like jewelry or belts.

What Should You Expect Before the Test?

No special preparation is needed, but tell your doctor if you’re pregnant, have a pacemaker, or have any metal implants. Avoid taking calcium supplements 24 hours before the scan if instructed by your provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Lower than expected bone density in the femoral region can indicate osteoporosis or other bone diseases. High density may suggest normal bone health or conditions like hyperparathyroidism. Results help guide treatment plans, such as medication or lifestyle changes to support bone strength.

Frequently asked questions

What Are the Possible Results?
Results are compared to a standard reference based on your age, gender, and body size. A lower score may mean your bones are less dense than typical, increasing fracture risk. Your doctor will interpret results in the context of your overall health.
How Often Should I Get This Test?
Frequency depends on your health. Typically, healthy adults may get it every 2–5 years. Those at higher risk (e.g., postmenopausal women, those with a family history of osteoporosis) may need it more often, as advised by your doctor.
Are There Any Risks or Side Effects?
The scan is very safe with minimal radiation exposure. Most people experience no discomfort. Rarely, some may feel mild discomfort from lying still or a slight metallic taste from the contrast dye (if used). Always discuss risks with your healthcare provider.
