What is CT?
Computed Tomography (CT) use X-rays to obtain fine slices of data through the body. These slices are then used to construct images of the examined body area. CT is only performed for specific body areas, and is not of the whole body. While used primarily for diagnosis, CT is also used in guiding the radiologist through a procedure, such as a steroid injection. As metal objects can interfere with X-rays, you may be asked to change into a gown, and remove objects such as glasses, jewellery, and even hearing aids. Please inform the radiographer if you are or you suspect you may be pregnant. All CTs are performed by registered Medical Imaging Technologists (Radiographers).
The CT scanner looks like a large doughnut, and has a flat table attached which moves through the middle. During your procedure you will lie flat on a table which will travel in and out of the CT scanner while the images are being acquired. Some procedures may require you to have an injection of X-ray dye (contrast) and this will be injected into a vein in your arm. The scan is performed while the dye is passing through your blood vessels. If you are to have an injection, this will flush through your body over the next 24 hours, however we recommend you drink plenty of fluids to assist in flushing the contrast out.
After your examination or procedure is finished, the information collected is then assessed by a Radiologist (Doctor who has specialised in Medical Imaging) and these reports will be electronically sent to your doctor with electronic images also being available.
Preparation for your CT
Some CT examinations, such as neck, chest, abdominal or renal (kidney) scans, and angiograms, also require special preparation. This preparation can consist of fasting, drinking water or oral contrast, and/or getting a blood test. It is imperative that you follow the preparation instructions you are given when you make your appointment. If you are unsure or have any questions regarding your preparation or examination please do not hesitate to call us on 9964 3757 and our staff will be more than happy to assist in any way we can.
Do I need an appointment?
Due to the varied nature of CT examinations and their preparations, appointments are required for all examinations. Appointments can be made by calling us on 9964 3757 with your request form and our staff will be happy to assist.
Who performs the CT?
All CTs are performed by registered Medical Imaging Technologists (Radiographers). A Radiographer is a specialist technologist who is registered with the Australian Health Practitioner Regulation Agency (AHPRA).
Examinations such as X-ray, CT, and MRI are all performed by Radiographers.
At Geraldton Radiology, we often have student radiographers, or registered radiographers who are training in new areas. In the event that a student/trainee performs your examination, they will be supervised either directly or indirectly by a senior Radiographer.
