Computed Tomography (CT)

What is a CT Scan?

A CT scanner uses a series of x-ray beams and a specialised computer to produce cross sections or slices (images) of organs and structures in the body.  The images when put together can be viewed as a 2D or 3D image.  CT can image different tissues including bones, soft tissues and blood vessels.

Patient Preparation

• Continue to take any prescribed medication unless you are told otherwise.
• If you are pregnant or there is any possibility you may be pregnant, please tell the radiographer before your scan.

What happens on arrival?

• Please report to the main reception area where you will be greeted by the administration staff. From there you will be escorted by a member of the imaging team to the imaging department.
• You will then be taken to the client changing area and changed for your scan if that is appropriate. We provide gowns, tunic and trouser sets, dressing gowns and slippers for your comfort. There is secure storage available.

What happens during the scan?

• A radiographer will take you into the CT scanning room and position you on a comfortable table where the examination will be explained to you.
• During the scan the table moves very slowly in and out of the scanner, which is a large ring shape rather like a doughnut.  Nothing touches you but you will hear the scanner working (it makes a whirring noise) and feel the table move.
• You may be asked to hold your breath for a few seconds at a time.
• The procedure time usually lasts 5 minutes.

What happens after your CT scan?

• There are tea and coffee facilities available which you can enjoy in the comfort of the imaging lounge after your scan.
• If you have changed for your scan you can get dressed and go home when you feel ready.
• The scan is reported by a radiologist.  Your result will be sent to your referrer and they will contact you directly.
