A bone density test, commonly known as a DEXA (Dual-Energy X-ray Absorptiometry) scan, is a specialized imaging procedure that measures bone mineral density. This non-invasive test plays a role in diagnosing osteoporosis, a condition that weakens bones, and assessing an individual’s risk of fractures. Preparing for this test often raises questions about appropriate clothing, particularly regarding bras. This article will provide clarity on what to wear to ensure accurate results.
Bra Guidelines for Your Bone Density Test
When undergoing a bone density test, the type of bra you wear can influence the accuracy of the results. Bras containing metal components, such as underwires, metal hooks, zippers, or any metallic embellishments, should be avoided. These materials can interfere with the X-ray technology used during the scan.
Soft bras, sports bras without any metal elements, or bralettes made entirely of fabric are generally acceptable. Some testing facilities may offer a gown for you to wear, which ensures there are no clothing-related interferences. If you are uncertain about your bra, it is always a good idea to bring an alternative or be prepared to change into a gown.
Why Specific Clothing Matters
The precise nature of a DEXA scan means that even small metallic objects can affect the imaging process. Dual-energy X-ray absorptiometry systems use two X-ray beams at different energies to differentiate between soft tissue and bone. Metal components absorb X-rays differently than bone and soft tissue, leading to artifacts or distortions in the images.
These interferences can falsely elevate bone mineral density readings, making accurate assessment of bone health difficult. Obtaining clear, reliable data is important for proper diagnosis, monitoring bone density changes, and guiding treatment decisions.
General Preparation Tips
Beyond bra choices, other clothing and accessories require consideration for a DEXA scan. It is advisable to wear loose-fitting, comfortable clothing that is free of any metal, including zippers, buttons, snaps, or buckles. Elastic waistband pants can be a good option due to their flexibility and lack of metal.
Before the test begins, you will typically be asked to remove all jewelry, body piercings, and any other metallic objects. If you have any uncertainties about what to wear or remove, contacting the testing facility beforehand for specific instructions is always recommended.
