Doctor explains Bone Density Scan (DEXA / DXA scan)

In this video Dr O'Donovan explains key things you need to know about a bone density scan (DEXA / DXA scan). A bone density scan, also known as a DEXA or DXA scan, is a quick and painless procedure that uses low-dose X-rays to measure the density of your bones. This test helps assess your risk of osteoporosis, a condition where bones become weak and more likely to fracture. It can also be used to monitor the effectiveness of osteoporosis treatment. What does a DEXA scan involve? You'll lie on your back on an X-ray table while a scanning arm passes over the area being scanned, usually the hip and spine. The scan measures how much radiation is absorbed by your bones, which indicates their density. The scan is quick, typically taking 5 to 20 minutes. It's a non-invasive procedure, and you can resume normal activities immediately afterward. Why is a bone density scan used? 1. Diagnosing osteoporosis: The scan helps determine if you have low bone density, a key factor in osteoporosis diagnosis. 2. Assessing fracture risk: It helps predict your risk of breaking a bone due to osteoporosis. 3. Monitoring treatment: Bone density scans can track the effectiveness of osteoporosis treatments over time. 4. Identifying other bone disorders: It can also be used to diagnose or monitor conditions like osteopenia, brittle bone disease, and osteomalacia. Here are some important things you need to know: A. Pregnant women should avoid bone density scans due to the radiation exposure. B. The scan results are often used in conjunction with other factors, like age and medical history, to assess overall fracture risk. C. While the scan is safe, it's important to discuss any concerns with your healthcare provider.
