What Is CT scan?
A CT scanner has an X-ray tube and detectors that move around the body in a circular motion as you move slowly through the scanner on the scanning table.
The CT scanner collects cross-sectional images that together with a powerful computer can build three-dimensional images that allow doctors to view soft tissue, organs, bone and blood vessels that can be difficult to see on conventional X-Rays.
At Perth Medical Imaging our Siemens CT scanner uses low dose scanning techniques with the latest software to produce the highest quality diagnostic images without exposing the patient to unnecessary radiation. Our highly trained and friendly staff will explain the procedure to you before your scan and answer any questions or concerns you may have. CT scans are fast and painless.
On occasion, your doctor may ask for a particular scan that requires an injection of contrast dye during the scan. This liquid shows in your body during the scan and can help detect a condition or enhance a particular structure. It has no lasting effects and will pass through your system in a few hours.
Before you attend for your CT scan please bring the referral form that your doctor gave you and any previous scan reports you have. If you think you may be pregnant if is important that you inform a member of staff before your examination.

What do I need to bring along to a CT scan?
When attending for your CT scan it is important that you bring the referral form from your doctor as it has valuable information about what type of scan is required. It is also important that you know any medications you are currently taking or any allergies that you may have. If you have had previous scans or x-rays from another practice that you think may be relevant, then please bring them or the scan report to your CT scan appointment as they can be very useful to our doctor when reporting on your scan.
Do I need to prepare for my CT scan?
Most CT scans do not require any special preparation. However, depending on the area of the body being examined, you may need to fast for a few hours beforehand. For some scans of the abdomen or bowel, you may be asked to drink water or a specific preparation drink. If this is necessary, the radiographer will explain the process and provide you with the required drink prior to your scan.
When you arrive at the clinic, you may need to complete a questionnaire if your scan involves a contrast injection. This form will ask about your medical history, allergies, and current medications.
Please let us know if you are taking any diabetes medication, have a history of kidney disease, or have previously experienced an allergic reaction to x-ray contrast injections.
What will happen during the scan?
For your CT scan, you will need to change into a patient gown, as clothing with denim, zips, or buttons can interfere with the images. Additionally, you will be asked to remove any metal items or jewelry.
Once you are prepared, you will lie down on the scanning table, which will move slowly through the scanner. During the scan, you may be asked to hold your breath for a few seconds to help capture clear images. If your scan requires a contrast injection, the radiographer will insert a small needle into your arm before the scan begins to administer the contrast when necessary.
How long will the CT scan take?
It will take about 10–15 minutes for your CT scan appointment. However, if you required to drink water beforehand, kindly allocate approximately 40 minutes to complete the procedure.
Are there any side effects?
Side effects from a CT scan are extremely rare, and the benefits of diagnosing or monitoring a condition typically far outweigh the risks associated with the small amount of radiation used. At Sydney CBD X-ray, we prioritize your safety by using advanced scanner technology and adhering to strict protocols to minimize radiation exposure without compromising image quality.
If your scan involves a contrast injection, it is common to feel a warm, flushed sensation during the injection, which is completely normal. In rare cases, patients may experience a mild allergic reaction to the contrast, such as temporary nausea or a rash. Severe allergic reactions are extremely uncommon. Our staff is always available to address any questions or concerns you may have about the procedure.
