CT (Computed Tomography) uses a combination of x-rays and high-powered computers to obtain cross-sectional images of the body. These images show all types of tissue, including lungs, brain, bones, muscles and abdominal organs, with great clarity. CT scans are also often used to guide fine needle biopsies and other minimally invasive procedures.
At Ascot Radiology, we have recently installed a Philips Brilliance 64 CT scanner. The Brilliance 64 utilises the very latest technology, producing extremely high quality images in a much shorter time. As well as performing scans of the brain, sinuses, chest, abdomen, pelvis, spine and bones, the advanced software also enables us to reconstruct detailed 3D images of the body, including the coronary arteries (CTA), and the bowel (Virtual Colonoscopy).
How is the CT scan performed?
You will be lying on a table which will move into the middle of the scanner just before the scan begins. During the scan, you may also feel the table move and you may be asked to hold your breath for a short time.
Due to the advanced technology of the CT scanner used at Ascot, the actual time you spend being scanned has been significantly reduced. You may spend as little as 5 minutes on the CT table.
Is there any preparation?
As the CT scanner uses x-rays, women should always inform their doctor, or the radiographer, if there is any chance they could be pregnant, prior to their scan.
Depending on the area being examined, you may be asked not to eat or drink anything for several hours before your appointment.
If you are having an abdominal and/or pelvic scan, you will be asked to drink several glasses of liquid containing contrast prior to your scan. The contrast will highlight your bowel on the scans and differentiate it from other organs and soft tissues.
Sometimes it is necessary to visualise certain blood vessels on your CT images. To do this, an injection of contrast (x-ray dye) will be administered into a vein in your arm during the scan.
