How does bone density testing work, and what is it for?


Recent research indicates there could be a high risk of spinal column fractures after stopping the drug. DXA can be used to evaluate your bone health in ways that go beyond measuring bone density. These tests are available at some but not all DXA facilities. page QCT scans can give very precise measurements of different parts of the bone structures. This can make it difficult to compare the results of different QCT scans. However, instead of emitting and detecting X-rays, they work with ultrasound.

For instance, X-ray and CT scans use radiation, but ultrasound scans may not be as accurate. Scientists have developed a wide variety of bone density testing methods. These can help doctors blog detect low bone density before it becomes severe or detect osteoporosis so that a person can begin treatment. These different bone density tests can scan different types of bone in the body.

Women and people assigned female at birth and anyone with a family history of osteoporosis should have regular bone density screenings. Ask your provider how often you need your bone density checked. Your healthcare provider will explain your test results and help you understand what they mean for your health. Your healthcare provider can help you make decisions about how to keep your bones strong. They can also recommend diet and lifestyle changes that may help to lower your risk of a fracture.


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 higher risk for fractures, including osteopenia and osteoporosis. Your bone density can be measured by a machine that uses low levels of X-rays to determine the proportion of mineral in your bones. During this painless test, you lie on a padded table as a scanner passes over your body. In most cases, only certain bones are checked — usually in the hip and spine. A bone density test, DEXA, measures the mineral content of the bones in certain areas of the skeleton.

Consequently, if your test on a peripheral device is positive, your doctor might recommend a follow-up scan at your spine or hip to confirm your diagnosis. X-ray scans, CT scans, and ultrasound scans can measure a person’s bone density. The results of bone density tests are shown as a T-score. The T-score refers to the density of a person’s bones when compared with the average bone density of a young person of the same sex. During a DXA or QCT scan, a doctor will use a machine that can emit and detect X-rays.

It’s an outpatient procedure, which means you won’t have to stay in the hospital. And there aren’t any needles or injections in this test. You may feel slightly uncomfortable lying on the table, depending on how have a peek here you’re positioned. But you’ll only need to stay in that position for a few minutes. The X-ray technologist will give you instructions before and during the test but they will leave the room to take the pictures.
