Standard computed tomography (CT) scanners use normal X-rays to make cross-sectional ‘slice-like’ pictures or images of the body.
This gives dual energy CT additional advantages over standard CT for a wide range of tests and procedures.
The scanner is fairly new technology that uses both the normal X-ray and also a second less powerful X-ray to make the images. This gives dual energy CT additional advantages over standard CT for a wide range of tests and procedures.
Preparation for a scan is identical to that required for a standard CT scan. Your referring doctor and the radiology facility where you are having the scan will provide you with information on any specific preparation required.
What happens during a dual energy scan is identical to that for a standard CT scan. You will not notice any difference in the examination whether you have a single energy or dual energy.
Dual Energy only takes about 15 minutes to perform. It is painless and non-invasive.
The scan itself is not associated with any immediate after effects. You should be able resume normal activities straight after the scan has been carried out.
Any potential after effects might be related to the injection of contrast medium if required.
