Computerised tomography (CT) is a specialised x-ray examination which combines many X-ray images to generate cross-sectional views of the body with the aid of a powerful computer. It produces detailed images of internal organs and structures of the body in both 2D and in 3D. A CT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.
Some CT scans require an injection of contrast medium, which shows up on the CT image and enables the Radiologist to identify areas more clearly.
If you have allergies, diabetes, kidney disease or asthma, or are pregnant, please discuss this when you make your appointment and with the CT staff.
The appointment generally takes about an hour.
We have multiple locations available for CT scans throughout New Zealand;
Before your Examination
Please phone us for an appointment and we will discuss:
Directions to your CT scan appointment
Details about the preparation for your scan including a period without food and drink
Details about the examination itself
Medical insurance and ACC if necessary
Post examination information
Please let us know as soon as possible if there is any reason why you cannot keep your appointment.
You will have time to read about the procedure, fill out a questionnaire as well as consent forms. A trained, experienced staff member will discuss the procedure with you. This is a good opportunity to ask any question you may have. In addition to a drink, an intravenous injection may be necessary during your scan. Both enable the radiologist to identify some organs or areas more clearly. If you have an injection, you may feel warm and have a metallic taste in your mouth.
You may be asked to change into a gown and remove all metallic objects such as jewellery, dentures, hearing aids, etc in the region to be scanned.
If an injection is needed, you will have an intravenous line inserted. Our staff will position you on a bed that will gently move through the scanner, stopping to scan relevant areas. You will be asked to remain very still throughout and you may need to hold your breath while some images are taken. If you have difficulty lying flat, or are uncomfortable in confined spaces, our staff will assist and make you more comfortable.
Scan times vary depending on the requested area of investigation and type of scan. A CT Medical Radiation Technologist (MRT) will discuss the procedure scan time with you prior to the procedure.
If you changed into a gown, you will be asked to change back into your clothes. Your personal items will be returned to you and you may be monitored for 10 minutes.
Your CT scan images will be interpreted by the radiologist and a report sent directly to your doctor who will discuss the results with you.
