Computed Tomography (CT)

A CT scan consists of a rotating X-Ray machine that generates images in a "slice-like" format, much like the slices in a loaf of bread. A scan is used to diagnose many conditions such as tumors, bone fractures, bleeding blood clots and more. Plus, they are invaluable for examining an organ's size and shape and in the evaluation of many different diseases. A majority of our technologists have furthered their career by becoming a Registered Computerized Tomography Technologist.

Preparation for Your Examination

  • Your physician or Imaging Services will inform you of specific instructions to prepare for the CT
  • Inform your physician or CT technologist if you believe there is a chance of pregnancy
  • If your examination requires intravenous (IV) contrast administration, you will be asked to complete a questionnaire. You may need specific blood work done prior to administration
  • If your examination requires oral contrast administration, you will be given specific instructions as to when to drink your contrast

CT Examination Description

CT examinations can vary in time from 10 minutes to more than an hour, depending on the area of concern. The technologist will place you on a table with a small pad. The table will move automatically through a large cylinder. Some scans require you to hold your breath, and the technologist will instruct you about this. An IV will be needed for contrast administration, if required. If you have any questions, please contact the Imaging Services Department at (812) 237-1625.
