What is a dual-energy CT scan?
Standard computed tomography (CT) scanners use normal X-rays to make cross-sectional ‘slice-like’ pictures or images of the body.
A dual-energy CT scanner is 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 procedure.
