You should always inform the CT technologist if there is any possibility that you are pregnant. CT scanning is generally not recommended for pregnant women unless medically necessary because of potential risk to the baby.
Some CT Scans require an injection of contrast medium. This highlights anatomy on the CT images and enables the Radiologist to identify areas more clearly. If you have allergies, diabetes, kidney disease or asthma, please discuss this with the receptionist when you make your appointment and with the CT staff.
There is some risk of an allergic reaction to the contrast materials.
Once NRL has received your CT request form from your referrer a CT administrator from NRL will contact you via the telephone. They will:
- Give you instructions on where to go for your CT scan.
- Ask questions about some of your medical history.
- Give you details regarding preparation before your scan - this may include a period without food and also drinking some specialised preparation a set time before your appointment. CT Colonography requires special preparation to clean out the large bowel.
- Give you details on how to arrange 'prior approval' from your medical insurance company for your CT examination.
- Give you information about what to do after your CT scan is completed.
- Send you out an information pack including a consent form and CT preparation instructions.
When you arrive you will be asked to change into a gown. It may be necessary to remove metallic objects such as jewellery, dentures, hearing aids etc.
A qualified CT Radiographer will position you on a bed that moves through the large "doughnut" shaped CT scanner. Images are taken when the appropriate area for diagnosis lies directly within the CT scanner. Though the scanning bed moves during the scan, you will be asked to remain very still and may be asked to hold your breath during your examination.
Your examination will be studied by imaging specialists (Radiologists). The formal report will be sent to your referring doctor within a few working days of your examination.
