Wear light, tight-fitting, and metal-free clothing to ensure accurate and hassle-free DEXA scan results.
Understanding What To Wear for a DEXA Scan?
A DEXA scan (Dual-Energy X-ray Absorptiometry) measures bone density and body composition using low-dose X-rays. For the test to be accurate, proper clothing is crucial. Wearing the wrong outfit can interfere with the scanner’s ability to get clear readings or even cause delays during the procedure.
The best clothing choices are those that minimize interference from metal objects and bulky fabrics. Metal pieces like zippers, buttons, belts, or jewelry can distort X-ray images. Bulky or loose clothing can create shadows or block parts of the body, leading to inaccurate results.
Choosing the right outfit not only speeds up the process but also ensures your scan results are precise. This article breaks down what you should wear—and what to avoid—to make your DEXA scan smooth and reliable.
Ideal Clothing Choices for a DEXA Scan
Lightweight and Tight-Fitting Clothes
The scanner requires a clear view of your body’s bone structure and soft tissue. Tight-fitting clothes like leggings, yoga pants, or fitted shorts work best. These garments sit close to your skin without wrinkles or folds that could confuse the scanner.
Loose clothes tend to bunch up or create extra layers that may block X-rays. Lightweight materials such as cotton or spandex blends reduce this risk because they conform well to your body shape without adding bulk.
Avoid Metal Components
Metal interferes with X-ray imaging by creating bright spots on the scan. Avoid clothes with:
- Zippers
- Buttons
- Snaps
- Buckles
- Underwire bras
Even small metal pieces like hooks on underwear or jewelry must be removed before the scan. Many clinics request you change into a hospital gown to eliminate this risk altogether.
Underwear Considerations
If you prefer not to wear a hospital gown, choose simple underwear without metal clasps or wires. Cotton briefs or sports bras without underwire are ideal. Avoid padded bras as they add thickness that may affect readings.
What To Wear for a DEXA Scan? – Clothing Do’s and Don’ts Table
| Do’s | Don’ts | Why It Matters |
|---|---|---|
| Tight-fitting leggings or shorts | Loose sweatpants or baggy jeans | Tight clothes reduce folds that block X-rays. |
| Cotton T-shirts without prints or logos | T-shirts with heavy prints or metallic threads | Plain fabric avoids image distortion. |
| No jewelry or accessories | Necklaces, watches, bracelets | Metal creates bright spots on scans. |
| No underwire bras; opt for sports bras instead | Padded bras with wires or clasps | Padded bras add thickness; wires interfere with imaging. |
| No belts or buckles | Pants with metal buttons and zippers | Metal hardware distorts results. |
The Role of Hospital Gowns in DEXA Scans
Many clinics provide hospital gowns for patients undergoing DEXA scans. This practice eliminates any risk related to clothing interference entirely. Wearing a gown ensures no hidden metals disrupt images and removes guesswork about what’s appropriate.
Gowns are typically lightweight, open-backed robes made from thin fabric that won’t affect X-ray penetration. They also make it easier for technicians to position you correctly on the scanning table without bulky clothing getting in the way.
If you want maximum accuracy and minimal fuss during your appointment, accepting a hospital gown is often the best bet.
How to Prepare If You Wear Your Own Clothes?
If wearing your own clothes is necessary due to comfort or preference:
- Select items from your wardrobe that meet all “do” criteria above.
- Avoid any clothing with hidden metal fasteners—check pockets and seams carefully.
- Remove all jewelry including piercings before arriving at the clinic.
- If possible, wear minimal layers; one thin layer is better than multiple thick ones.
- If uncertain about an item’s suitability, bring a change of clothes just in case.
This preparation helps prevent delays caused by needing to change at the clinic last minute.
Shoes and Accessories During Your DEXA Scan Appointment
While shoes don’t affect scan results directly because you’ll be asked to lie down during imaging, it’s wise to wear comfortable footwear since you might walk around before and after your appointment.
Accessories such as watches, rings, necklaces must be removed prior to scanning because metals interfere strongly with X-rays. Even small amounts of metal can cause artifacts in images that lead to misinterpretation of bone density data.
Many clinics provide lockers where you can store personal items safely during testing.
The Impact of Clothing on Scan Accuracy Explained
X-rays used in DEXA scans pass through soft tissue but are absorbed differently by bone versus fat versus muscle. Any foreign material—especially metals—can absorb or reflect X-rays abnormally.
This leads to “artifacts” which appear as bright spots or shadows on images. These artifacts confuse software algorithms analyzing bone mineral density (BMD) and body fat percentages.
For example:
- A zipper near the hip could mimic extra bone mass falsely elevating BMD scores.
- A bulky sweatshirt might cast shadows hiding subtle bone loss areas.
- An underwire bra wires could create bright lines disrupting chest area measurements.
By wearing appropriate clothing free of metals and bulk, these errors are minimized ensuring more trustworthy results clinicians can rely on for diagnosis and treatment planning.
The Step-by-Step Process During Your Scan Appointment
Knowing what happens during a DEXA scan helps understand why proper attire matters so much:
- Check-in: You arrive at the clinic wearing your chosen outfit (or hospital gown).
- Dressing:If needed, staff will ask you to remove shoes, jewelry, belts, and change into a gown if you brought inappropriate clothes.
- Lying down:You lie flat on the scanning table while technicians position you carefully for optimal imaging angles.
- The scan:The machine passes low-dose X-rays over specific body parts (usually hip/spine) taking only minutes per area.
- Completion:You get dressed again if changed into a gown; results are later analyzed by radiologists.
Each step depends heavily on minimizing obstructions so technicians can quickly complete scans without interruptions caused by adjusting clothing repeatedly.
How Clothing Choices Affect Different Types of DEXA Scans?
DEXA scans aren’t just for bones—they also measure total body composition including fat mass and lean muscle mass distribution. The accuracy of these measurements depends equally on what you wear.
For whole-body scans assessing fat percentage:
- Tight-fitting clothes ensure consistent compression across soft tissue areas allowing precise fat mapping.
For focused bone density scans (hip/spine):
- The absence of metal near joints prevents false high readings caused by reflections off zippers/buttons close by.
No matter which type of scan is scheduled, sticking strictly to recommended attire guidelines guarantees trustworthy data every time.
