Are you scheduled for a bone density scan? Perhaps your doctor has recommended it for you or someone you know. You may have several questions about what to expect during the procedure. How long does a bone density scan take? In this article, we will answer some commonly asked questions about bone density scans.

What is a bone density scan?

A bone density scan, also known as a dual-energy x-ray absorptiometry (DEXA) or DXA scan, is a non-invasive and painless procedure used to measure the density of bones. It is primarily performed to diagnose osteoporosis and assess the risk of fractures.

How long does the procedure take?

The duration of a bone density scan can vary, but on average, the procedure takes approximately 15 to 30 minutes. The actual scanning time may be even shorter, ranging from 5 to 15 minutes, depending on the area being examined.

Is any preparation required before the scan?

There is usually no specific preparation required before a bone density scan. However, it is advisable to wear loose and comfortable clothing, as you may be asked to change into a gown. Additionally, you should avoid wearing any metal objects such as jewelry or belts, as they can interfere with the scan.

What happens during the scan?

During a bone density scan, you will be asked to lie on a padded table while a scanning arm passes over your body. The scanner uses a small dose of ionizing radiation to measure bone density, and it sends the data to a computer for analysis. You may be asked to hold your breath momentarily to minimize any potential blurring of the images.

Is the procedure painful?

No, a bone density scan is not painful. It is a non-invasive test that does not involve any injections or incisions. You may feel slightly uncomfortable lying still on the table, but the actual scanning process is painless.

Are there any risks associated with bone density scans?

Bone density scans involve a very low exposure to radiation, and the risk associated with the procedure is exceedingly minimal. The benefits of early detection and prevention of fractures far outweigh any potential risks. However, if you are pregnant or suspect you might be, it is important to inform your doctor beforehand, as the procedure may be contraindicated in such cases.

Are there any post-procedure instructions?

There are usually no specific post-procedure instructions after a bone density scan. You can resume your regular activities immediately. However, it’s essential to discuss the results of the scan with your doctor, who will provide you with appropriate guidance based on the findings.

How often should bone density scans be done?

The frequency of bone density scans depends on various factors, including age, gender, medical history, and risk factors for osteoporosis. In general, it is recommended that women over the age of 65 and men over the age of 70 should have bone density scans every two years. Your doctor can provide personalized recommendations based on your unique circumstances.

In conclusion, a bone density scan is a quick and painless procedure that plays a crucial role in diagnosing osteoporosis and assessing fracture risk. The scan typically takes 15 to 30 minutes, with the actual scanning time being even shorter. There is no specific preparation required, and the procedure involves minimal risks. Remember, it’s essential to discuss the results and any concerns with your doctor, who will determine the appropriate course of action based on your individual needs.
