X-ray

What are X-rays?

X-rays are the most frequently used form of medical imaging. Conventional X-rays are performed for a variety of reasons, but are most commonly done to detect problems in the bones and chest.

An X-ray image is produced when a small amount of radiation is passed through a body part to expose a sensitive surface (historically a film) that is positioned on the other side. The image is produced as a result of the ways in which different internal structures absorb the radiation. For example, bones tend to stop the X-rays and cause a definite shadow. The lungs, which are filled with air, allow nearly all the X-rays to pass through, causing very little shadow.

What will happen during my X-ray procedure?

Before undergoing an X-ray, you will be asked to remove all jewellery and objects containing metal, as metal can block the image and interfere with test results. You may also be asked to change into a gown provided by us. A technologist will then position you so that the part of your body being examined is set between the X-ray machine and a receptor surface which is sensitive to X-rays. In some cases, body parts not being imaged will be covered with a lead apron, to stop the X-rays. The technologist will then ask you to stay very still for a moment. The X-ray equipment will be activated, sending a very brief beam of X-rays. This is a painless procedure; you will not feel anything.

X-rays will usually need to be taken with you in different positions. Once all necessary views have been captured, the technologist will process the images. You may be asked to wait a few minutes while we confirm that the images are acceptable. If they are blurred, you may have to repeat the procedure.

How do I prepare for my X-ray study?

No special preparation is required for general X-rays. However, it is important to tell the technologist, before the exam, if you are or may be pregnant.
