Computerized Tomography (CT)

What is a CT?

A computerized tomography (CT) scan uses X-rays taken from different angles to create cross-sectional images, or slices, of your soft tissues, blood vessels, and bones. These images are more detailed than those produced by regular X-rays.

A CT scan can provide a near-complete picture of all parts of the body that can help diagnose diseases and injuries and facilitate the creation of treatment plans. For this reason, CT scans are often performed on those suffering from accidents or other forms of trauma.

What to Expect During a CT Scan

CT scans are pain free and usually conducted in a hospital or outpatient facility. In this procedure, you will lie on a table that will then slowly move into a tunnel where a scanner will rotate around your body to generate images. It is normal to hear buzzing or whirring noises during this time.

During a CT scan, you will be able to communicate with a technician via an intercom. He or she may request that on occasion you hold your breath in order to produce the clearest images possible.

Uses of CT Imaging

CT scans are useful for:

  • Detecting internal bleeding or muscle and bone disorders, such as bone tumors and fractures
  • Identifying the location of an infection or blood clot
  • Diagnosing and monitoring conditions such as cancer, heart disease, liver masses, and lung nodules
