Computed tomography, also known as a CT or CAT scan, is a painless, non-invasive way to see inside the body using X-ray imaging. During a CT scan, multiple images are taken from different angles. A computer combines the images to create digital cross-sectional images, or slices, of soft tissue, organs, blood vessels and bone. The slices can often be combined to create 3-D pictures.
Computed tomography is often used to help identify and diagnose conditions such as cancer, infections, trauma and cardiovascular disease. A CT scan can be performed even if you have a pacemaker or implantable cardioverter-defibrillator.
Many Scripps facilities offer 64-slice computed tomographic scans and some use low-dose CT scans — which result in lower doses of radiation exposure. However, all CT scans result in exposure to radiation, so it is important to let your care team know if you are pregnant to avoid potential risk to a developing child.
