Low Dose CT
Computed Tomography (CT) uses an X-ray tube and multiple detectors to provide incredibly rapid imaging of your anatomy. You will be asked to lie on a table in the middle of the ring while the scan is taken. Nothing will touch you during the scan. Our systems are also equipped with dose reduction technology which ensures that the lowest possible radiation dose is used during a scan, which will still allow for high quality diagnostic pictures to be obtained.
Our advanced CT systems provide major benefits to patients with the following features:
CT Services include:
- Wide CT opening – a wide bore reduces anxiety caused by claustrophobia
- Dose reduction technology – ensuring the lowest possible radiation dose is employed
- Rapid acquisition – a fast imaging time means the patient doesn’t need to lie still for as long or hold breath for as long
- Lower table height – the CT table can be lowered to allow easy access for patients with mobility issues
- Dynamic Volume Imaging
Your scan will be conducted by a specially trained CT Radiographer. Prior to being scanned you may be asked to undress and remove any metal (jewellery, buttons and zips) from the body area being scanned. You will be supplied with gown and a locker to store your clothing. Your radiographer will answer any questions you may have about your scan. Some CT scans require an injection of IV contrast. If this is necessary the radiographer will insert a small plastic tube (cannula) into a vein in the arm. This cannula will be used to give you the injection of contrast once you are in the scanner. Once you are ready for your scan you will be taken into the scan room.
The CT scanner is round with a large circular hole in the middle. You will be asked to lie down on a bed that will slide through the hole in the machine. The table will move in and out as it takes pictures and you may be given instructions such as holding your breath for a few seconds as images are taken. CT scans are often very quick, most CT scans take only 5 to 10 minutes in the machine.
Sometimes we use iodinated contrast to help us better visualise the tissues being scanned. Contrast may be taken orally or by intravenous injection (or both). You will be advised when you make your appointment if a contrast injection will be required.
As CT scans require x-rays, there is some radiation involved in the scan. Please advise our staff if you are or think you may be pregnant. A very small number of people may be allergic to the intravenous contrast injection. Please advise our staff if you have had an allergic reaction to iodinated contrast previously.
Some CT scans require preparation such as fasting. You will be advised of any preparation for your CT scan when you make an appointment.
