X-Ray

An X-ray is a fast, painless procedure commonly used to capture images of bones and teeth for diagnosis and to guide treatment. X-rays are typically conducted in hospital departments or dentist surgeries by trained specialists to look at bones, teeth, and internal organs.

How an X-ray Works

X-rays are a form of radiation that passes through the body. They are invisible and painless. A detector picks up the X-rays after they’ve passed through the body and turns them into an image.

Bones absorb more radiation than soft tissue, and will appear white in the image. Softer tissues, such as the lungs and heart, will show up darker. The radiographer captures and assesses the images.

What Can an X-ray Be Used For

X-rays are a quick and effective method for viewing bones and certain body tissues. They are commonly utilised for:

• Identifying bone fractures and dislocations.
• Detecting chest infections and lung conditions.
• Assessing dental and oral health.
• Diagnosing arthritis and other joint issues.
• Evaluating digestive tract conditions with contrast studies.

X-rays provide a fast and efficient way to gain insights into a variety of health concerns, particularly in emergency and orthopaedic settings.

What to Expect When Receiving an X-ray

Before the Appointment

Before an X-ray, you can eat, drink, and take any usual medications unless told otherwise by the doctor. If you have a contrast agent, your doctor will give you specific instructions on how to prepare.

If you're pregnant, tell the hospital. X-rays are usually avoided during pregnancy unless necessary.

Wear loose and comfortable clothing, and avoid jewellery and zippers, as you may need to remove them before your X-ray.

During the Appointment

During the X-ray, you will lie on a table, stand against a flat surface, or position the required body part on the table. You may be given a contrast agent: this is a substance that acts like a temporary dye, helping reveal more internal details in your body. The radiographer will position the part of your body to be examined and carefully aim the X-ray machine. The radiographer will leave the room to operate the machine.

You will need to stay still for a clear image. The radiographer will take X-rays from different angles to get a full picture.

Risks and Complications

X-rays expose the body to minimal radiation and are very low risk. However, it’s important to be aware of the risks and complications.

You may have a reaction to the contrast agent the radiographer gives you. This could result in blurry vision, mild allergic reactions, and changes in stool colour.

How to Recover Following an X-ray

Usually, there are no after effects, and you can go home straight away after your X-ray.  A radiologist will look at the X-ray images and discuss the results with you on the same day or at a later date. Sometimes, it takes a few days to receive a full report.
