CT Scan

A computerized tomography scan, also called a CT scan, is a type of imaging that uses X-ray techniques to create detailed images of the body. It then uses a computer to create cross-sectional images, also called slices, of the bones, blood vessels and soft tissues inside the body. CT scan images show more detail than plain X-rays do. A CT scan has many uses. It's used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.

Why it's done

Your healthcare professional may suggest a CT scan for many reasons. For instance, a CT scan can help:

Diagnose muscle and bone conditions, such as bone tumors and breaks, also called fractures.
Show where a tumor, infection or blood clot is.
Guide procedures such as surgery, biopsy and radiation therapy.
Find and watch the progress of diseases and conditions such as cancer, heart disease, lung nodules and liver masses.
Watch how well certain treatments, such as cancer treatment, work.
Find injuries and bleeding inside the body that can happen after trauma.
