Are bone density scans safe?
A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. You may also hear it called a DEXA scan. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break.

- Summary
In the United States, 18.8% of females aged 50 or older have osteoporosisof the femur neck (hip) or lumbar spine (lower back). Only 4.2% of males have osteoporosis. Decreased bone density and strength can lead to weakened bones that easily break. A bone density test helps screen, diagnose, and monitor the effects of conditions that put people at hi...
A bone density test (such as a DEXA scan) is relatively safe. However, you will be exposed to low-dose radiation during the test. Two very low-dose X-ray beams pass through your body's tissue to determine how dense and strong your bones are.
Pretest
Once you have checked in and completed the admission paperwork, you will be taken to an exam room. At this time, you might be asked to change into a gown. Your personal items will be put in a safe place (like a locker) while you are having the test.
Throughout the Test
During the test, you will lie on your back (supine) on the table. Your legs will rest, straight or bent, on a padded box. The detector above will pass over your body, and the X-ray generator will go under you. The two images will be combined and sent to a computer. You will need to lay very still. You might be asked to hold your breath for a few seconds to ensure a clear image. The test takes between 10-30 minutes, depending on the device used and the body area being scanned.
Post Test
When the test is over, you can change back into your regular clothing, gather your items, and go home.
Side effects of a bone density test are rare. You may go back to your normal activities immediately. In addition to the bone density test, your healthcare provider may want you to have bloodwork done to analyze your calcium and vitamin D levels.
A specially trained doctor called a radiologistwill interpret the bone density test. The results will be available to your healthcare provider a few business days after the scan has been completed. The results of your bone density test will have two scores: a T-score and a Z-score. 1. T-scores compare your bone density to a healthy young person wit...
A bone density test, such as a DEXA scan, measures how much calcium and minerals are in your bones. This information helps your provider determine if you are at is at risk for fractures. A bone density test can help diagnose osteopenia and osteoporosis, which decrease bone density and strength, but does not show arthritis. It is a painless procedur...
A bone density scan compares your bone density with the bone density expected for a young healthy adult or a healthy adult of your own age, gender and ethnicity. The difference is calculated as a standard deviation (SD) score.
May 28, 2024 · A DXA scan (bone density test) is a quick, painless way to check your bone health. It’s similar to a regular X-ray, but measures the strength and mineral content of your bones instead of just taking pictures of them. Providers use DXA scans to screen you for osteoporosis, osteopenia and other conditions that can silently weaken your bones.
A bone density test determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break. The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone.
Oct 3, 2018 · This is when a bone density scan shows you have lower bone density than the average for your age, but not low enough to be classed as osteoporosis. Osteopenia does not always lead to osteoporosis. It depends on many factors.
A bone density scan (DXA) scan can be used to check the density of your bones. If your bone density is low, you have a higher risk of a bone fracture. On this page. What is a bone density scan?
