Plain X-rays are one of the most common diagnostic procedures in healthcare. They are primarily used to visualize and assess bones and other internal structures of the body to detect fractures, infections, and other conditions. For more in-depth information on X-rays and the professionals involved, refer to the introductory page. Please note that this article covers ‘plain‘ X-ray imaging and not fluoroscopy; refer to the Fluoroscopy FAQs for details on fluoroscopic procedures.

What is an X-ray? #
X-rays are invisible energy waves that can pass through your body to create images of your internal structures, helping doctors understand what’s going on inside. Given their energy and the possible risks, X-rays are expected to only be done as indicated by a doctor.
What is Plain X-ray imaging, and how is it different from Fluoroscopy? #
Plain X-ray imaging, also known as conventional or static X-ray imaging, captures still images of your body. To make it more relatable, this means X-ray images are like a static photographic image. Fluoroscopy, on the other hand, provides real-time images. For more on fluoroscopy, check the Fluoroscopy FAQs.
Why is an X-ray required? #
There are several reasons for which X-rays can be requested. Your doctor is therefore in the best position to answer this question. However, common reasons for X-ray investigations may include fractures, infections, bone abnormalities, and abdominal swelling.
How are X-rays named? #
X-rays are mostly named based on the area being examined. For example, a Chest X-ray looks at the Chest, an Abdominal X-ray focuses on the Abdomen, and a Foot X-ray shows your Foot.
Note: One common assumption is that a single X-ray image can show every part of the body. This is not correct. X-rays are designed and carried out in such a way that the X-ray energy is only focused on the area of interest (described as Collimation).
How does Plain X-ray work? #
An X-ray machine directs a controlled amount of radiation through the body, creating an image on a X-ray detector or X-ray plate. Different body parts of your body absorb the radiation differently, allowing a radiologist to interpret the resulting image.
How does an X-ray test feel? #
X-ray tests are painless. You might experience slight discomforts while the Radiographer positions you, but this typically lasts for only a few seconds.
Do I need to stop my medication? #
Generally, you won’t need to stop any medications. However, if unsure, consult your doctor.
What should I wear for my X-ray? #
Wear loose, comfortable clothing, as you may be asked to change into a hospital gown.
Can I eat before my X-ray? #
Most X-rays don’t require fasting, although certain types (e.g., abdominal X-rays) may need you to avoid food for a few hours.
I think I may be pregnant. Should I inform the Radiographer? #
Yes. Always inform your referring doctor first as well as your Radiographer if you suspect a pregnancy. Special precautions or alternative imaging options may be used to avoid exposing your fetus to radiation.
Are X-rays safe if I’m not pregnant? #
Yes. X-rays are generally safe when used properly. Don’t worry, most trained Radiographers know the proper use of X-rays. The radiation exposure is minimal, the machines are optimized, and Radiographers sometimes take steps to minimize it further.
Can I use the Bathroom while waiting for my X-ray? #
Yes, unless instructed otherwise for a specific exam, you can relieve your bladder and use the bathroom if you have to.
How long will my X-ray take? #
The actual exposure lasts only a fraction of a second. The whole process, including preparation and positioning, usually takes 5-15 minutes, depending on the body part.
What will happen during my X-ray? #
During the test, you’ll be asked to lie on a table or stand against a surface. It may feel cold when your body touches it (due to the temperature of the room). The Radiographer will position you and the X-ray machine. Staying still is essential, as movement can you’re your images.
Why might I need to stay with my patient during the X-ray? #
For an uncooperative child or adult, a parent or relative may need to stay in the room. You’ll be given a lead apron to wear for protection.
What should I expect after the exam? Will I become radioactive? #
You won’t feel different or become radioactive after the X-ray. The radiation exposure is minimal and doesn’t remain in your body. You can resume normal activities immediately.
Why didn’t I receive my results right away? #
The Radiographer captures the images, which are then interpreted by a radiologist. Your doctor will discuss the results with you.
Will my doctor order additional tests? #
This is best answered by your doctor. Sometimes, an X-ray is enough, and sometimes, it is not. If more information is needed, your doctor may recommend further tests to confirm a diagnosis.
Why might I need a repeat X-ray? #
In rare cases, an additional view may be required to confirm a diagnosis, or the initial image quality was insufficient. You can ask the Radiographer questions on this if it happens.
I don’t feel comfortable with a male or female Radiographer. Can I request someone else? #
Yes. In most centers, you can inform the Radiographer of your preference, and they can arrange for a chaperone or another person to be present to ensure your comfort.
Can I request alternatives to an X-ray? #
This may be possible. It is best to discuss this with your managing doctor first. Alternatives like ultrasound or MRI, which don’t use radiation, may be available depending on your condition.
Why should I remove my accessories? #
Items like jewelry or other accessories can cause ‘artifacts’ which are unwanted shadows and appearances that may look like issues (diseases) on an X-ray image. Please, remove all items as instructed by your Radiographer.
What other items can cause artifacts? #
Accessories around the area of your X-ray, such as waist beads, keys, glasses, hearing aids, necklaces, earrings, and hair accessories, can interfere. Inform your Radiographer of any additional items you think they may have forgotten about.
Conclusion #
Plain X-rays are safe and quick, ensuring diagnosis are done faster and effectively. While they are generally safe, guidelines and instructions must be strictly followed.
Always follow your Radiographer instructions and speak with your healthcare provider if you have any additional concerns.
