CT Scan in Perth

Need to have a CT scan in Perth? Contact the team at Imaging Central to book in your CT scan appointment or book online.

We’re conveniently located in Claremont and Morley and our CT scans are performed using a 128 or 256 slice CT capable of up to 60%-80% radiation dose reduction.

What is a CT scan?

Computerised Tomography (CT) uses multiple X-rays to create pictures of sections of your body. Imaging Central uses a state-of-the-art Multidetector CT for very short scan times and excellent image quality.

Patients needing a CT scan in Perth are required to lie on a flat, narrow, bed which moves in and out of a short tube. A high-tech computer then analyses the detected X-rays and converts the data to a series of 2D and 3D images for your radiologist to examine.

How do I prepare for my Perth CT scan at Imaging Central?

It is important to remember to bring any previous X-ray, CT or other medical imaging films or reports that you have at home. Your radiologist will compare to the previous films in order to make a judgment about the current examination.

Metal objects such as watches, keys, coins and jewellery can affect the images and will have to be removed. You may be provided with a gown to wear instead of your own clothes.

If you are pregnant or think that you may be pregnant, tell your doctor and IC staff, as X-rays can affect an unborn baby.

For some scans, it may be necessary to drink a liquid prior to the scan, and have an injection in the arm vein which will help your radiologist see areas such as bowel more clearly, and also show how some organs are working. If you are having one of these scans, our staff will give you precise instructions for your test.

It may be necessary to administer intravenous contrast for your scan and it is important to tell your doctor and IC staff if you have diabetes or kidney problems before your scan, as contrast may further decrease your kidney function.

When you make a booking for a CT scan in Perth that will require IV contrast you will be asked for your age and whether you are diabetic. If you are over 60 or diabetic we will need the results of a recent blood test that shows your kidney function. If you have not had one within the past few months we will ask you to get your doctor to write you a referral for a blood test or you can come to see us and we will provide you with one. We need to establish that your kidneys work well before we give you an injection of contrast. It is also important that you are well hydrated so we will ask you to drink at least 1 litre of water prior to coming in for your scan.

What happens during my CT scan?

You will be asked to lie down on the scanner table, which moves slowly into the centre of the scanner machine. The CT scanner is more of a doughnut with large hole, rather than a long tunnel (which is how people may describe an MRI machine). There is a lot of room inside the gantry. It is quite rare for people to feel claustrophobic within our CT scanner.

Others will leave the room during your scan because CT uses radiation. Imaging Central’s CT staff will control the movement of the scanning table from behind a screen, but they will see you and hear you at all times. You will receive instructions from the CT staff about breathing and positioning for the scan.

For some scans it will be necessary to inject a special liquid called “contrast media” through your arm vein, to improve visualisation of structures within your body. If you are having a contrast injection, you might feel a temporary flush or warm feeling over your body. A small percentage of people may also feel temporary nausea and a sensation of passing urine but generally these feelings pass quickly.

How long does a Perth CT scan at Imaging Central take?

The actual scan may only take a matter of seconds, but more time will be taken to position you and the scanning equipment for picture accuracy and quality, such that the scan make take up to 20 minutes. Lying still may be uncomfortable for a long period of time, and you will be able to talk to the Imaging Central’s CT staff at all times. The majority of scans will require you to be on the table for between 5 and 10 minutes.

When the test is over, it may be necessary to wait while the images are reviewed to see if more are needed.

What are the risks of a CT scan?

CT scans use X-rays which will expose your body to a low level of radiation. The level of radiation will depend on the number of images taken. The level of radiation will be kept to a minimum.

The increase in the risk of cancer as a result of the exposure of the levels of radiation you receive in a CT scan is unknown, but is considered by experts to be very small. In fact, the amount of radiation received from many CT scans is less than the the annual amount of  background radiation we are exposed to from the earth, sun, food and buildings.

This very low risk is outweighed by the benefits of the information provided by the CT scan. No radiation remains after the test.
