CT Scan

A computerized tomography scan (CT or CAT scan) uses computers and rotating X-ray machines to create cross-sectional images of the body. These images provide more detailed information than normal X-ray images. They can show the soft tissues, blood vessels, and bones in various parts of the body. A CT scan may be used to visualize the:



  Head

  Shoulders

  Spine

  Heart

  Abdomen

  Knee

  Chest



During a CT scan, you lie in a tunnel-like machine while the inside of the machine rotates and takes a series of X-rays from different angles. These pictures are then sent to a computer, where they’re combined to create images of slices, or cross-sections, of the body. They may also be combined to produce a 3-D image of a particular area of the body.

 

A CT scan has many uses, but it’s particularly well-suited for diagnosing diseases and evaluating injuries. The imaging technique can help your doctor:


  diagnose infections, muscle disorders, and bone fractures

  pinpoint the location of masses and tumors (including cancer)

  study the blood vessels and other internal structures

  assess the extent of internal injuries and internal bleeding

  guide procedures, such as surgeries and biopsies

  monitor the effectiveness of treatments for certain medical conditions, including cancer and heart disease
