What is a CT scan?
A CT scan (Computerized Tomography scan) uses X-rays and a computer to produce a series of cross sectional 2D and 3D images. It can give great details of foot joints that can be obscured and difficult to see on normal X-Rays.
What happens during the CT scan?
You’ll be asked to lie on the scanning table and we’ll ensure you’re comfortable, so you can stay as still as possible. If you require an injection of contrast media, we will inject it via a suitable vein (usually in your arm). We might ask you to hold your breath or not to swallow at certain points when the scanner is taking the images. The scanner is open on two sides to allow you to see around the room and the radiographer will be able to see and hear you throughout the examination. If you’re uncomfortable at any point, just let the radiographer know.
How long does the CT scan take?
The scanning process will take about 20 minutes and if you have had an injection, you’ll need to remain in the department for the next 30 minutes. Therefore, depending on whether you’ve been asked to arrive an hour early, or if there is a delay due to an emergency, your maximum time in the Imaging department could be approximately 90 minutes.
Who does the CT scan?
The scan is performed by a radiographer and your results are reported by a specialist Consultant Radiologist.
What happens after the scan?
The results and images will be sent to your referring clinician at Fitter Feet For Life. Unless you have had an interventional procedure then there are no restrictions on your normal activity – you can eat and drink normally, drive and return to work immediately after the scan.
Are there any risks?
A CT scanner uses more radiation than an x-ray, and is equal to the natural radiation we receive from the atmosphere over a period of about three years.
Women who are or might be pregnant must inform a member of staff in advance.
Should you be given the contrast injection, this usually causes nothing more than a warm feeling passing around your body and a ‘metallic’ taste in your mouth, but the questionnaire we give you will assess your suitability for this.
Despite these risks bear in mind that there may be greater risk from missing a serious disorder by not having the scan.
Where does the CT Scan take place?
The Fitter Feet For Life Team can refer you to the private hospital of your choice to have an CT scan.
You will be seen for a follow up consultation at 'Fitter Feet for lIfe' to discuss the best treatment for your condition and a member of the team will provide the treatment of your choice. This can range from conservative care such as foot orthoses, physiotherapy, laser therapy, and steroid injections, to surgery of varying types.
