What is an X-⁠ray? How Does an X-⁠ray Work?

An X-ray, also known as radiography, is one of the oldest and most frequently used forms of medical imaging. It’s a quick, non-invasive procedure that uses a small amount of radiation to create images of the structures inside your body, particularly your bones. At Scope Radiology in Clayton, Victoria, we use digital X-ray equipment, which gives your doctor clear pictures to review.

How Does an X-ray Work?

X-rays use electromagnetic radiation to create pictures. When an X-ray beam passes through your body, different tissues absorb varying amounts of radiation. Dense materials like bone absorb more radiation and appear white on the image. Softer tissues, such as muscle, fat, and organs, absorb less and appear in shades of grey. Air, like in your lungs, appears black.

Our digital X-ray images are ready to view on screen straight after the scan.

Common Uses of X-rays

X-rays are used to look at many parts of the body, for example:

• Bone Fractures and Breaks: The most common use, quickly identifying bone injuries.
• Joint Injuries: Assessing dislocations, arthritis, and other joint problems.
• Chest X-rays: Looking at the lungs, heart and ribs, for example when your doctor is checking a cough, chest pain or a suspected chest infection.
• Abdominal X-rays: Identifying issues like kidney stones, bowel obstructions, or swallowed objects.
• Dental X-rays: Used by dentists to check for cavities and other dental problems.

Preparing for Your X-ray Appointment

Generally, very little preparation is needed for an X-ray. Here’s what you should know:

• No Fasting: You can usually eat and drink normally before your X-ray.
• Medications: Continue to take your regular medications unless otherwise advised by your doctor.
• Clothing: Wear loose, comfortable clothing. You may be asked to remove jewellery, glasses, and any metal objects, as these can interfere with the X-ray images. Depending on the area being examined, you might be asked to change into a gown.
• Pregnancy: Tell us before your appointment if you are pregnant or think you might be. X-rays use radiation, which can harm an unborn baby, so we may use a lead apron or your doctor may consider a different test.
• Referral: Please bring your referral letter from your GP, dentist, specialist or allied health professional.

What to Expect During the Procedure

When you arrive at Scope Radiology Clayton for your X-ray:

1. Check-in: Our friendly reception staff will greet you and confirm your details and referral.
2. Preparation: A qualified radiographer will explain the procedure and position you correctly. You may be asked to stand, sit, or lie on a table.
3. The Scan: You will need to remain very still for a few seconds while the X-ray is taken. You may be asked to hold your breath briefly. The process is quick and non-invasive.
4. Completion: Once the images are captured, you can usually leave immediately and resume your normal activities.

Your Results

After your X-ray, our radiologists will carefully review and interpret your images. A detailed report will then be sent to your referring doctor, typically within 24 to 48 hours. Your doctor will discuss the findings with you and explain what they mean for your health and any next steps.
