What it is

CT scans

A computed tomography (CT) scan is an imaging method that uses X-rays to create cross-sectional pictures of the body.


Good to know

These scans can help diagnose tumors, hemorrhages, head injuries and bone abnormalities. Inside the CT machine, the X-ray tube circles around the patient taking pictures as it rotates. These slices can be viewed two-dimensionally or added back together to create a three-dimensional image of a body structure.
