Head, neck, chest, abdominal, renal and pelvic scans:

Spinal and musculoskeletal scans:
No preparation required.
Some CT examinations require an injection of iodinated contrast medium into an arm vein, to allow imaging of the blood vessels and vascular tissues. If required, this will be discussed prior to the injection and you will be asked to complete a questionnaire and provide consent.
You may be asked to change into a gown and/or remove jewellery.
You will lie on a table which is slowly moved into the doughnut shaped CT unit. Housed within the CT is an X-Ray tube which rotates around you. Detectors capture the X-Rays passing through the examined area for the computer to interpret into images. You may be asked to hold your breath for a few seconds during the scan.
Our Radiologist will review the images and issue a report. Once completed, the report will be sent electronically to your referring health professional.
You will receive a small dose of X-Ray radiation.
Please advise the radiographer if you are, or think you may be pregnant.
Problems related to the contrast injection are very rare. The injection will be discussed prior to the examination and you will be asked to complete a questionnaire and provide consent.
CT examination times are normally between 5 and 20 minutes. This varies according to the type and reason for your examination.
