Procedures / Computed Tomography (CT scan)
What is the test for?
A CT scanner uses xrays to obtain data which is then processed by a special computer. Detailed images of soft tissue, blood vessels and bone are produced.
What is the preparation for the test?
For studies requiring contrast media: (brain, chest, abdomen, pelvis or neck) Clear fluids only for 2 hours prior. Drink 600ml 30minutres prior. If you are asthmatic or diabetic please notify us.
Abdomen: certain studies of the abdomen require 600ml of water to be consumed 30 minutes prior to the appointment. You will be informed if you need to follow this preparation.
How is the test performed?
The duration of an examination depends on which part of the body is being examined. If you are asthmatic or diabetic it is very important that you inform reception staff. You may need to change into a gown and you will be asked to lie on a narrow bed. The bed is designed to slide through a large 'O' shaped xray tube. De-pending on the specific examination you will be oriented to pass either head first or feet first through the tube. A radiographer controls the scanner from behind a partition near the scanner. The table will move dur-ing the examination as images are obtained. You might be given breathing instructions during the scan - these are recorded on the machine and played back to you when necessary.
Will I feel anything?
If you receive a contrast injection you may feel a slight warmth and metallic taste.
How long will it take?
Most scans take 10 minutes.
