What to Expect at Your X-Ray Appointment

What happens during an X-ray

An X-ray is a quick imaging test that takes pictures of the inside of your body using radiation. A technician positions you in front of a machine, asks you to hold still for a few seconds, and the machine sends radiation through the area being examined. The radiation passes through soft tissue and comes out the other side, creating an image on a sensor. The whole appointment usually takes 15 to 30 minutes, though the actual exposure lasts only a few seconds.

You won't feel anything during the X-ray itself — no pain, no heat, no sensation at all. The technician will step behind a protective barrier during the exposure and may ask you to hold your breath briefly so the image stays sharp. Different body parts require different positioning: a chest X-ray has you stand facing the machine, while an ankle X-ray might have you sit with your foot extended.

Key Takeaways

• Wear loose, metal-free clothing to your appointment, or the facility will provide a gown, because metal shows up on X-rays and blocks the image.
• Tell the technician if you are pregnant or think you might be, because X-rays use radiation that can affect a developing fetus.
• The appointment itself takes 15 to 30 minutes, but most of that is positioning and paperwork — the actual exposure lasts seconds.
• A radiologist reviews your images after the appointment and sends a report to your doctor, usually within 24 hours.

What to wear and bring

Wear comfortable, loose clothing without metal fasteners, zippers, or underwire. Metal appears white on X-rays and blocks the image underneath it, so the technician may ask you to remove jewelry, belts, or bras with metal components. If you cannot remove an item, tell the technician — they may be able to position you around it or ask you to change into a gown.

Bring your insurance card and photo ID. If your doctor's office sent you with a paper order or referral, bring that too. Some facilities ask you to arrive 10 to 15 minutes early to complete paperwork, so check your appointment confirmation for the exact arrival time.

Before your appointment: what to prepare

Most X-rays require no special preparation. You can eat, drink, and take your regular medications as normal. If your appointment is for a specific body part — a hand, foot, or shoulder — make sure that area is clean and free of lotion, makeup, or bandages if possible, because these can interfere with image quality.

If you have had X-rays of the same area recently at another facility, ask whether those images can be sent to your current provider. This saves time and reduces unnecessary radiation exposure. Call your appointment location a day or two before if you have questions about what to bring or wear.

Pregnancy and X-rays

Tell your doctor and the X-ray technician immediately if you are pregnant or think you might be. X-rays use radiation, which can affect a developing fetus, especially in the first trimester. Your doctor may decide to postpone the X-ray, use an alternative imaging method like ultrasound, or proceed with extra shielding if the X-ray is medically necessary.

If you have already had an X-ray and then discovered you were pregnant, do not panic — a single X-ray delivers a very small dose of radiation. Contact your doctor to discuss any concerns, but most single X-rays pose minimal risk.

After your X-ray: when you get results

You will not receive results at the appointment itself. A radiologist — a doctor who specializes in reading medical images — reviews your X-rays after you leave. This usually takes 24 hours, though urgent cases may be read the same day. The radiologist writes a report and sends it to the doctor who ordered the X-ray.

Your doctor's office will contact you with results and next steps. If you do not hear back within a few days, call your doctor's office to ask about the status. You can also request a copy of your X-ray images and the radiologist's report for your own records.

Different types of X-rays and what they show

Chest X-rays are the most common and show your lungs, heart, and ribs. They can reveal pneumonia, fluid in the lungs, or broken ribs. Bone X-rays show fractures, arthritis, or bone density issues and are used for hands, feet, arms, legs, and spine. Dental X-rays are small images of your teeth and jaw taken at the dentist.

Abdominal X-rays can show bowel obstruction or free air in the abdomen, though they are less detailed than CT scans. Sinus X-rays show the air-filled cavities in your face and can reveal infection or blockage. Your doctor will have ordered the specific type your situation requires.

Radiation exposure and safety

X-rays use ionizing radiation, which carries a small risk of cell damage over time. However, a single X-ray exposes you to less radiation than you receive naturally from the sun and cosmic rays in a year. The benefit of diagnosing a broken bone or infection usually outweighs the small risk from one X-ray.

If you have had multiple X-rays or other imaging tests with radiation in a short time, mention this to your doctor. They can track your cumulative exposure and decide whether additional imaging is necessary or whether an alternative test like ultrasound or MRI would be safer. Technicians wear protective gear and follow strict safety protocols because they are exposed to radiation repeatedly throughout their careers.

Frequently Asked Questions

Do I need to remove all my clothes for an X-ray?

No. You only need to remove clothing and metal items from the area being X-rayed. For a chest X-ray, you remove your shirt and bra if it has metal. For a foot X-ray, you remove your shoe and sock. The technician will tell you exactly what to remove.

Can I bring someone into the X-ray room with me?

Usually not, because anyone in the room is exposed to radiation. However, if you are a minor, very anxious, or unable to follow instructions, a parent or caregiver may be allowed in the room wearing a lead apron. Ask the technician when you arrive.

What if I move during the X-ray?

Movement blurs the image, and the technician may need to repeat the X-ray. This means a second exposure to radiation. The technician will give you clear instructions on how to position yourself and will tell you when to hold still. If you are in pain or uncomfortable, tell them — they can adjust the position to make it easier.

How long does it take to get X-ray results?

A radiologist typically reviews your images within 24 hours and sends a report to your doctor. Urgent cases may be read the same day. Your doctor's office will contact you with results, usually by phone or through a patient portal if your provider has one.

Is an X-ray the same as a CT scan?

No. An X-ray is a single two-dimensional image taken from one angle. A CT scan takes many X-ray images from different angles and uses a computer to create detailed three-dimensional pictures. CT scans show more detail but use more radiation and take longer.
