Cone beam CT
What is a cone beam CT?
Cone beam imaging is also a CT, but it is a smaller scanner, and the benefit is that it is a low-dose scanner. Optimal imaging of musculoskeletal structures such as wrists, elbows, feet, knees, sinuses, and other facial structures. Orthopaedic doctors can perform scans while the patient stands, using weight-bearing to assess joint movement.
What preparation is needed?
No specific preparation is required.
What to expect during the procedure?
A radiographer performs the examination, which should not take longer than 15 minutes. You will be positioned in the scanner, and it will be expected of you to keep completely still for about 2 minutes.
What are the risks?
Although the scanner uses an extremely low dosage of X-rays – so little in fact that the radiographer will remain in the room with you throughout the entire examination – it is still important to inform the radiographer if you are pregnant or expect that you might be pregnant.
What happens after the procedure?
After the examination, you can resume your regular daily activities. You will receive a copy of your images, and a detailed report will be sent to your referring doctor, who will discuss it with you.
