What to Expect of a DXA Scan

Introduction to DXA Scans

A Dual-Energy X-ray Absorptiometry (DXA) scan is commonly used in the United Kingdom to measure bone mineral density (BMD). This diagnostic tool is crucial for assessing conditions such as osteoporosis and for evaluating fracture risk. It provides precise data by using low-dose X-rays to measure the amount of calcium and other minerals in a segment of bone.

Before the Scan

Before undergoing a DXA scan, you typically won't need to follow any specific dietary restrictions. However, it is essential to inform your healthcare provider if you have recently had any procedures involving barium or if you've taken any calcium supplements, as these could affect the scan's accuracy. Wearing loose, metal-free clothing is recommended to prevent interference with the X-ray images.

The Scan Process

Upon arrival, you will be asked to lie on a padded table. The scanner will pass over your lower spine and hips, though sometimes the forearm is scanned if the spine or hip cannot be scanned. The process is non-invasive, meaning no injections or incisions are involved. During the scan, you'll need to stay still to ensure clear and precise images. Most DXA scans are completed within 10 to 20 minutes.

What to Expect During the Scan

The DXA scan is pain-free, and while you may hear some mechanical noises from the scanner, it doesn’t cause discomfort. The low-level X-rays used in the scan expose you to minimal radiation—much less than a standard chest X-ray. The technologist operating the machine will be in a separate room but will be able to communicate with you throughout the procedure.

After the Scan

There is no recovery period needed following a DXA scan, so you can return to your daily activities immediately. Your results will typically be analyzed by a radiologist or a specialist. The findings will be shared with your referring healthcare provider, usually within a week. Based on your BMD results, your doctor will discuss any necessary lifestyle changes, medications, or follow-up tests.

Conclusion

A DXA scan is a safe, quick, and effective method to evaluate bone health. Understanding what to expect can help alleviate any concerns and ensure you are prepared for the procedure. This diagnostic tool plays a vital role in detecting and managing bone-related conditions, helping you maintain optimal health.

What to Expect from a DXA Scan

Introduction to DXA Scans

A DXA scan is a test that checks how strong your bones are. It is often used in the UK to see if someone has weak bones, a condition called osteoporosis. The scan uses a small amount of X-ray to look at the minerals like calcium in your bones.

Before the Scan

Before the DXA scan, you usually don't need to change what you eat. Tell your doctor if you've recently had a test with barium or if you take calcium pills. This can change how the scan works. Wear loose clothes without metal so the images are clear.

The Scan Process

When you arrive, you'll lie on a soft table. A machine will scan your lower back and hips. If it can’t scan these areas, it may scan your arm. The test doesn’t use needles, and you won’t feel pain. You need to stay still so the images come out clear. The whole scan takes about 10 to 20 minutes.

What to Expect During the Scan

The DXA scan does not hurt. You might hear some noise from the machine, but it won’t bother you. The X-rays are very low and safe, much less than a normal X-ray. The person running the machine will be in another room but can talk to you.

After the Scan

You can go back to your normal activities right after the DXA scan. A doctor will look at your results and send them to your healthcare provider, usually in a week. Your doctor will talk to you about the results and if you need to change anything or take more tests.

Conclusion

A DXA scan is a safe and quick way to check bone health. Knowing what will happen can help you feel calm and ready. This test is important for finding and treating bone problems, so you can stay healthy.
