CT: Computerized Tomography

Computerized tomography (CT) scan combines a series of X-ray images taken from different angles and uses computer processing to create high resolution cross-sectional images, or slices, of the bones, blood vessels and soft tissues. A CT scan has many uses, but is particularly well-suited to quickly examine patients who may have internal injuries from car accidents or other types of trauma. A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment. Contrast agents are often used to improve anatomical details during CT imaging.

Doctors may order CT Scans to help with the following:

  • Diagnose muscle and bone disorders, such as bone tumors and fractures
  • Pinpoint the location of a tumor, infection or blood clot
  • Guide procedures such as surgery, biopsy and radiation therapy
  • Detect and monitor diseases and conditions such as cancer, heart disease, lung nodules and liver masses
  • Monitor the effectiveness of certain treatments, such as cancer treatment
  • Detect internal injuries and internal bleeding
