If you’re scheduled for a DEXA scan, you may wonder what to wear to ensure accurate results and a smooth appointment. The good news is that preparing for a DEXA scan is simple, and what you wear plays a small but important role in the process.
The Best Clothing to Wear
For the most accurate scan, wear comfortable, lightweight clothing without metal. Metal can interfere with the imaging, so it’s best to avoid items like zippers, buttons, snaps, underwire bras, or metallic threads. Ideal options include:
- Athletic shorts or leggings without zippers
- A cotton t-shirt, tank top, or sports bra (no metal)
- Soft, elastic waistbands instead of belts
Many people choose to wear workout or athleisure clothing, which is typically metal-free and comfortable for lying still during the scan.
What to Avoid Wearing
Certain clothing items can slow down your appointment or require you to change. Try to avoid:
- Jeans or pants with metal zippers or rivets
- Bras with underwire or metal adjusters
- Jewelry, watches, or hair accessories with metal
- Thick sweaters or layered clothing
If metal is detected during your scan, the technician may ask you to remove the item or change into a gown to ensure accurate results.
Do You Need to Change Clothes?
In most cases, you won’t need to change as long as your clothing meets the guidelines above. However, some facilities offer gowns as an option if needed. Removing metal objects like keys, phones, wallets, and jewelry is standard before the scan begins.
Does Clothing Affect Accuracy?
Yes—metal objects can distort DEXA images, which may affect the accuracy of measurements like body fat percentage, lean mass, or bone density. Wearing appropriate clothing helps ensure your results truly reflect your body composition and can be reliably compared over time.
Comfort Matters Too
A DEXA scan typically takes 10–15 minutes, during which you’ll lie flat on a padded table. Choosing comfortable clothing helps you remain still and relaxed, contributing to a smoother experience.
Final Tips Before Your Scan
- Wear metal-free, fitted clothing
- Remove all jewelry beforehand
- Avoid clothing with thick seams or embellishments
- When in doubt, choose simple athletic wear
Preparing properly allows your DEXA scan to be quick, accurate, and stress-free—so you can focus on what matters most: gaining clear insights into your health.
