What is CAT or CT Scan?

A Computerized Axial Tomography scan, CAT or CT scan, is an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. A CT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.  A large donut-shaped X-ray machine takes X-ray images at many different angles around the body.  These images are than compiled and sent to a radiologist for interpretation.

CT scans are performed to analyze the internal structures of various parts of the body including but not limited to:

  • Head
  • Spine
  • Abdomen
  • Pelvis
  • Sinuses
  • Chest
  • Extremities
  • Teeth and gums

Occasionally, oral and/or intravenous contrast medium is administered to enhance the images of your exam.

What to expect during your examination.

Patients are placed on a table that moves into the center of a large donut-shaped machine that takes the X-ray images around the body. The process can take from a half an hour to an hour and a half, depending on the procedure.  The technologist will be viewing the procedure through a glass window and can communicate with the patient through an intercom.
