Grace Cottage offers bone density scanning (DEXA) to evaluate bone mineral density. A bone density scan can help diagnosis osteopenia (bone loss) and osteoporosis (weak bones). A higher bone density indicates stronger bones. Treatment of early bone loss can reduce your risk of fractures and other serious health problems. The bone density scan is non-invasive and painless.
How to Prepare for Your Test
- On the day of your exam, you may eat normally. Do not take calcium supplements for at least 24 hours before your exam.
- Wear loose, comfortable clothing. Avoid zippers, belts or buttons or any other objects made of metal that may interfere with the x-ray images.
- Women should always inform their physician and technologist if there is any possibility that they are pregnant. Another type of test may be recommended.
A radiologist will analyze the images and send a signed report to your primary care or referring physician, who will discuss the results with you. DEXA scan results are reported as “T scores” and “Z scores.” The T score shows the amount of bone you have compared with a young adult of the same gender with peak bone mass. The T score is used to estimate your risk of developing a fracture. The Z score reflects the amount of bone you have compared with other people in your age group of the same gender and size.
