• A Computed Tomography (CT) scan shows more detail than a regular X-ray and can be used for any part of the body. Involving a narrow X-ray beam that circles around one part of the body, a CT scan shows the bones, organs and soft tissues more clearly than X-rays.

• A CT scan uses an X-ray machine to take several pictures from different angles, providing a highly detailed cross-sectional image. This process is repeated to produce a number of images to create a 3D picture. The computer stacks these scans one on top of the other to create a detailed image of a patient’s organs or bones.

• During a CT scan, a patient lies on a table inside a large, doughnut-shaped CT machine. As the table slowly moves through the scanner, the X-rays rotate around the patient’s body. A whirring or buzzing noise is usually heard.

• While X-rays consist of images in 2D formats and are usually used to detect fractures and tumours, 3D pictures from CT scans can be used to identify location of internal bleeding and monitor effectiveness of certain treatments.

• CT scans play a fundamental role in cancer treatment. They are regularly used to plan radiotherapy treatment to support doctors in deciding the amount of tissue to be exposed to the radiation treatment. This allows for more precise and effective treatment.

• Doctors also compare CT scans over time to see how a tumour is responding to treatment.

Once we’ve received your referral and booked a slot for your CT scan, you’ll receive confirmation with all the details of your appointment.

Most CT scans requires a dye to be administered into your body. You will be asked not to eat or drink anything except water for up to six hours before your appointment. You will be informed well in advance if this applies to you.

When you arrive at our hospital, our friendly reception staff will bring you to the basement. You’ll be then be greeted by the Radiographer, who will show you to the changing room, where you can lock away your valuables and change into a gown if necessary. He will also explain the examination to you and answer any queries that you may have.

You will be asked to complete a consent form stating that you are agreeable to do a contrast CT scan. The doctor will explain to you the common side effects from the dye and will be on stand-by during your scan in case any contrast allergy happens. You will then be taken through into the CT room, where you will lie on the CT couch and be slid into the scanner. The Radiographer will update you on the progress of the scan from the control room.

After your scan, you can collect your valuables from the changing room, and go back home. Your CT scan images will be read by our Consultant Radiologist who will then generate a report by end of the day.
