Let's walk through the top five things to know before your first bone density scan.
1. It’s a Quick, Non-Invasive Scan
A bone density scan, often called a DEXA or DXA scan (Dual-Energy X-ray Absorptiometry), is a simple and painless procedure. If you’re anxious about medical tests, you can rest easy knowing there are no needles, injections, or special prep required. You won't be enclosed in a narrow tunnel; instead, you'll lie comfortably on a padded table while a mechanical arm passes over your body. The entire process is quick, usually taking only 10 to 15 minutes to complete. It uses a very low dose of radiation—less than a standard chest X-ray—to create detailed images of your bones, most commonly the hip and lower spine.
2. What to Wear (and What to Avoid)
Choosing the right outfit can make your appointment even smoother. The goal is to wear loose, comfortable clothing without any metal. Zippers, buttons, buckles, and underwire bras can interfere with the X-ray images and may need to be removed. It’s best to opt for simple attire like sweatpants, leggings, or athletic shorts and a plain t-shirt. You may be asked to change into a gown to ensure the images are as clear as possible. Also, avoid taking calcium supplements for at least 24 hours before your scan, as they can potentially affect the results.
3. What to Expect During the Test
When you arrive for your bone density testing near me appointment, a technologist will guide you through the process. After confirming you aren't wearing any metal, they will ask you to lie on your back on the padded DEXA table. To ensure your body is positioned correctly for the best images, the technologist may use foam blocks to support your legs and keep your hip or spine aligned.
Once you are in position, the scanner's arm will move slowly above you. It's important to stay as still as possible during this time to prevent blurry images, but you can breathe normally. The technologist will be in a nearby room, able to see and speak with you throughout the scan. The entire experience is designed to be quiet and comfortable.
4. How Your Results Are Interpreted
After the scan, a specialized radiologist doctor near me will analyze the images and interpret the results. Your bone density is reported using two main scores: a T-score and a Z-score.
T-score
Your T-score compares your bone mineral density (BMD) to that of a healthy 30-year-old adult, which is typically when bone mass is at its peak.
- A T-score of -1.0 or above is considered normal.
- A T-score between -1.0 and -2.5 indicates low bone mass, or osteopenia.
- A T-score of -2.5 or below is diagnosed as osteoporosis.
Z-score
Your Z-score compares your bone density to that of other people of your same age, sex, and ethnicity. While a T-score is the primary measure for diagnosing osteoporosis, a Z-score can be helpful if your score is unusually low. It may suggest that something other than aging is causing bone loss, prompting your doctor to look for secondary causes.
5. How Often You May Need Follow-Up Scans
The frequency of follow-up DEXA scans depends on your initial results and risk factors. If your bone density is normal, your doctor may not recommend another scan for several years. However, if you have osteopenia or osteoporosis, follow-up scans are typically recommended every one to two years. These regular checks allow your doctor to monitor any changes in your bone density, assess whether your treatment plan is working, and make adjustments as needed. Consistency is key, so finding reliable bone density testing near me is important for tracking your progress accurately over time.
