X-ray, the most common diagnostic procedure, uses short wavelength radiation that can penetrate solid body masses, resulting in film images of bones, cartilage and other internal anatomical features. X-rays are completely painless and, in fact, involve no direct patient-equipment contact.

How do I prepare for x-rays?

There is no need to change your normal routine prior to your exam. Depending on the parts of the body to be x-rayed, you may need to remove jewelry or any other metallic accessories that may be detected. As always, let your technologist know if you are pregnant or have metal implants or similar devices. Their presence will not affect the exam, but knowing about them will make it easier for your physician to read the x-rays.

What will happen during my x-ray?

You may be asked to change into a gown to avoid x-ray detection of clothing zippers and buttons. After changing, you will lie, sit or stand in a certain position at the machine depending on the view to be taken. Your technologist will position you prior to taking the x-ray. Your technologist will then step behind a lead enclosure and activate the machine. You will hear a clicking or buzzing noise which is normal.

How long will my x-rays take?

Each x-ray only takes a few minutes. Your total exam time will depend on the number of views taken.

Are x-rays harmful?

X-rays are made up of ionizing radiation, so long-term exposure can be harmful. However, the amount of radiation you are exposed to during an x-ray exam is minimal.

If x-rays aren't harmful, why do the technologists stand behind lead shields?

During a normal work week, an x-ray technologist or radiologist could potentially be exposed to hours of radiation from the exams they perform. Because of the cumulative effect such exposure could have on them over many years, they stand behind a lead barrier to protect themselves from long-term exposure.
