What is a CT scan?
Computed 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 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 may have to be removed. You may also 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 imaging central staff, as X-rays can affect an unborn baby.
It may be necessary to administer a contrast for your CT, either orally, directly through your bloodstream (intravenously) or both. It is important to tell your doctor and imaging central staff if you have an allergy to the contrast which is composed of Iodine.
When you make a booking for a CT scan that will require intravenous contrast you will go through a screening process to make sure it is safe for you to have it. Some factors include, your age, kidney function, and diabetic status. Depending on this, you may be required to have a blood test prior to 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 short and wide and it is quite rare for people to feel claustrophobic during a scan.
For safety reasons, family members will leave the room during your scan and Imaging Central’s CT staff will control the movement of the scanning table and will see you and hear you at all times. You will receive instructions from the CT staff about breathing and positioning for the scan.
If you are having a contrast injection discussed earlier, 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 urination but 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 accuracy and quality, such that the scan makes take up to 20 minutes. However, 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 additional images are required.
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 having 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 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.
