What to Wear to a CT Scan
Wear soft pull-on pants and a plain tee with no metal over the area being scanned, and sleeves you can push above the elbow if you are getting contrast. Four formulas plus the layer and shoe picks, so the scan is the only thing you have to think about.
A CT scan uses X-rays, not a magnet, so the metal rule is narrower than it is for an MRI: metal only matters if it sits over the part being scanned. Wear soft pull-on pants with an elastic waist, a plain cotton or polyester top, and no jewelry, and you will almost always stay in your own clothes. If you are getting contrast dye, add one requirement: sleeves you can push above the elbow, because a nurse needs a vein in your arm.

Four Outfit Formulas for a CT Scan
1. The Default Two-Piece
Soft pull-on pants, a plain tee, wire-free bra if you wear one, real socks, slip-on shoes. Nothing fastens with anything harder than a drawstring. This clears a head, chest, abdomen, or pelvis CT without a gown. Leave rings, watches, and hair clips at home rather than in a locker.
2. The Contrast Setup
About half of CT scans use iodine contrast through an IV in the crook of your arm, and that detail outranks everything else in your outfit. Wear short sleeves, or long sleeves loose enough to push past the elbow and stay there. A fitted knit that grips your forearm gets rolled and bunched on the table. You are also told to drink a lot of water first, so an easy waistband matters more than it sounds.

This is the one most people get wrong, and it is the whole reason a CT is not an MRI. A magnet cares about metal anywhere in the room. An X-ray beam only cares about metal in the slice it is imaging. An underwire bra is a problem for a chest CT and irrelevant for a knee CT. Work out which body part is being imaged, keep hardware off that zone, and ignore the rest.
4. The Cold-Room Layer
Imaging suites run cold because the scanner electronics need it, usually 65F to 70F, and the table is unheated plastic under a thin sheet. You are lying still, producing almost no muscle heat. Add a metal-free knit crewneck and a thicker sock. Techs hand out blankets, but arriving already warm is easier.
Do and Don't
- Do check which body part is being scanned before you get dressed. That fact decides your whole outfit.
- Do wear sleeves that push above the elbow if contrast is on the order.
- Do bring socks you could walk a hallway in.
- Don't wear jewelry, hairpins, or metallic thread over the scan area.
- Don't assume a bra is fine because CT is not magnetic. Underwire still streaks a chest image.
- Don't leave anything in your pockets. Emptying them on the table is where delays start.
The Best Shoes for a CT Scan
Slip-on loafers are the most useful thing you can put on your feet for imaging. You will be asked to step out of them beside the table, then put them back on while holding a bag and an arm with a cotton ball taped to it. Laces are a two-hand job at the exact moment you have one hand. A leather slip-on with no eyelets and no shank is also nothing to explain at the screening desk.
Clean, cushioned socks are not optional. Imaging floors are hard tile held at the scan room temperature, and many centers walk you a short corridor in socks alone. A merino micro crew handles that better than a thin dress sock, and merino holds its insulating value even damp.

Shop This PickAvoid metal eyelets, buckles, a steel shank, or a heel you cannot take off standing on one foot. Avoid brand-new shoes, since a cold waiting room is a bad place to find a hot spot. And avoid flip-flops in winter, because that floor is cold and you will be on it a while.
Mistakes People Make
- Treating a CT like an MRI. People strip off every scrap of metal, including the bra they could have kept on for a knee scan, then sit underdressed in a cold building. The rule is local to the scan field, not global to the room.
- Wearing a fitted long-sleeve top to a contrast scan. The sleeve has to clear the elbow and stay clear. If it does not, you are changing anyway, and now while an IV is being placed.
- Forgetting that CT is often same-day and multi-stop. Bloodwork, a contrast drink, a wait, then the scan. Dress for two hours in a cold building, not six minutes on the table.
- Choosing clothes with magnetic closures. Magnets are metal. Safe near a CT in a way they are not near an MRI, but they still throw a bright streak across the image if they sit over the scan area.
Why This Approach Works
The reason metal matters at all in CT is beam hardening. Dense material absorbs the low-energy part of the beam and lets the high-energy part through, and the reconstruction software cannot reconcile the difference, so it draws bright and dark streaks out from the object. A single underwire can smear a band across both lungs. That artifact is confined to the slices the metal sits in, which is why the fix is positional rather than total.
The temperature side gets ignored more often. Scan rooms sit around 65F to 70F at low humidity, and you spend the scan motionless on an unheated surface. Lying still cuts your heat output to near resting baseline, so 68F on a CT table registers about the way the mid-50s do when you are walking around. A knit crewneck near 300gsm and a merino sock closes most of that gap.

Shop This PickFrequently Asked Questions
What should I wear for a CT scan? Soft pull-on pants with an elastic waist, a plain cotton or polyester top, no jewelry, and slip-on shoes. Keep metal off whichever body part is being imaged.
Can I wear a bra during a CT scan? For a head, neck, knee, or foot CT, yes. For a chest, abdomen, or spine CT, a wire-free bra is usually allowed and an underwire one usually is not, because the wire sits in the imaging field.
Can I wear jewelry to a CT scan? Take it off before you leave the house. Earrings and necklaces interfere with head and neck scans, and rings get in the way of the IV line.
Do you have to undress for a CT scan? Often no. If your clothes have no metal over the scan area and no thick seams, most centers let you stay in them.
Can I wear deodorant for a CT scan? Yes. Deodorant is a mammogram restriction, not a CT one, because there it is the aluminum showing up on a low-dose breast X-ray.
