What is an X-ray, and why is it done?

X-ray technology is a painless and rapid diagnostic procedure that shows images of internal organs, including bones. This diagnostic method is used in the following cases:


  • Diagnosis of fractures and bone infections: Any fractures and infections in the bones can be detected using X-ray technology.
  • Tooth Decay: Dentists use this technique to check the status of the teeth.
  • Bone cancer: If there is a tumor in the bones, it is diagnosed using the X-ray procedure.
  • Osteoporosis: Doctors can use special X-ray based devices to check bone density based on X-ray.
  • Arthritis: This disease is swelling and tenderness in the joints. X-ray technology detects any inflammation in the joints.


  • Lung diseases: Diseases such as lung cancer, tuberculosis, and pneumonia can be diagnosed using this test.
  • Blocked blood vessels: To check for vascular problems, first, a contrast material containing iodine is injected, and then the status of blockage of the vessels is checked using an X-ray.
  • Breast cancer: Mammography is an X-ray-based diagnostic procedure that helps examine breast tissue.
  • Heart Enlargement: X-rays help doctors diagnose problems such as heart enlargement.


  • Digestive problems: To diagnose digestive problems, barium is first used orally, or by enema, then X-rays are used to check for gastrointestinal problems.
  • Swallowed objects: For example, if your child swallows objects such as coins or keys,  the X-ray can determine the position of the swallowed object in the body.

How is an X-ray done?

In this diagnostic method, X-rays are emitted inside the body. Different parts of the body absorb different amounts depending on their density. Bones and metals are marked white on X-rays. Fat and muscle are seen as shades of gray, and the air inside the lungs is marked as black.

In some X-rays, the patient must use a contrast material containing iodine or barium to make the image clearer.


Different types of X-ray imaging

  • Radiography or conventional X-ray: In this method, a single image is recorded and later evaluated by the doctor. Mammography is a type of radiography to image the breast tissue.
  • Fluoroscopy: This method requires a high radiation dose and is often used to place medical devices such as stents.
  • Computed tomography (CT): In this method, the amount of radiation is high. The CT image is the result of the reconstruction of individual X-ray projections.


How to prepare for the test?

Different X-ray tests require different preparations that your doctor will explain to you before the test. Before performing the test, you will be asked to remove jewelry, glasses, and any metal objects. These objects are shown on the X-ray. It is also necessary to use an iodine or barium contrast agent orally or as an injection or an enema before performing some tests.


During the test

X-ray is performed in a doctor or dentist’s office, emergency unit, and wherever an X-ray machine is available. SNOHC performs full-service X-ray imaging in-house in Las Vegas. Radiation exposure from this technique is low, and its benefits far outweigh the risks.

A technologist puts your body in a position to get the most appropriate views. To prevent having blurry images, you must stay still during the test (often, you need to hold your breath to avoid moving). Completion of the X-ray may take from a few minutes to more than an hour for a bone X-ray.


After the test

After the test, you can continue your daily activities. If you have used a contrast material before the test, you should drink plenty of fluids to help your body excrete it.

After performing the test, the results can be seen on the monitor. Our SNOHC specialists will interpret the results and send a report to your doctor.


Do X-rays have side effects?

The discovery of X-rays is very valuable because it has helped to diagnose many diseases to date. This method not only helps diagnose diseases but also plays a role in controlling the treatment process or even the placement of medical devices such as catheters or stents.

X-ray radiation exposure is very low, and it can be said that the benefits of these tests outweigh their side effects. Radiation sensitivity depends on your age, sex, body region, and radiation dose. Accordingly, children are more sensitive than adults. If you are pregnant or may be pregnant, tell your physician before taking the test. Because X-rays may be dangerous for the unborn baby, other methods, such as ultrasound, can replace X-rays in pregnant women.

Contrast injection in some people may cause the following problems:

  • Warmth or flushing
  • The taste of metal in the mouth
  • Nausea
  • Itching and hives
  • Lightheadedness


Information for patients

X-ray imaging should be performed only after careful consideration of the patient’s needs. Keep in mind that the diagnostic benefits of this method outweigh the small radiation risk.
