Computed Tomography (CT)

What it is, what to expect and what CT equipment looks like.

Computed Tomography (CT) is a fast diagnostic exam that combines the power of X-rays with computers. A CT scan is a diagnostic tool that allows the radiologist to see the location, nature and extent of many different diseases or abnormalities inside your body.

CT scanning can be used to obtain information about organs (liver, pancreas, intestines, kidneys, adrenal glands, lungs, and heart), blood vessels, the abdomen and bones.

While many providers are focused on dose-reduction efforts, the immediate benefits of CT typically outweigh the long-term risks.

There has been a lot of talk in the news and throughout the medical community about radiation exposure (also called “dose”) and CT imaging. This is due to the concern that the radiation we are exposed to over the course of our lifetime accumulates, thus increasing our potential health risks.

We believe lowering radiation dose is important in keeping any possible risks from radiation exposure to a minimum. All of our clinical teams are committed to capturing the high-quality diagnostic images using the appropriate amount of radiation. These are some of the steps we take:

  • Our technologists carefully position you within the scanner in an effort to obtain optimal images of the area of interest.
  • Your unique size and weight are considered when setting up the exam.
  • Our scanners are equipped with advanced technology (real-time dose modulation) to minimize your exposure and maintain maximum image quality during the scanning process.
  • Our centers and CT scanners are accredited by the American College of Radiology which includes annual, rigorous quality and safety reviews.


Providers are not equal. Be an advocate for yourself.

Discuss radiation dose with your doctor when deciding where to go for your CT scan as dose varies among imaging providers. 


Industry Radiation Resources

Step 1: We will call you prior to your appointment to discuss specific preparation instructions and your past imaging exams. Be sure to tell us if you are nursing or if there is a chance you are pregnant. We’ll give you a general expectation in terms of time you’ll be in our center, but on average you should budget around 30–45 minutes for the CT scan from check-in until departure.

Step 2: On the day of your exam, please arrive 15 minutes early to check-in and bring prior imaging results with you, if instructed.  

Step 3: Our CT technologist will help you onto the scanner table. If you are having an exam with contrast, it may be administered through an I.V. in your arm or hand, or it may be an oral contrast which you drink in advance. If your exam requires an oral contrast, our center associate will tell you during your appointment preparation call.

Step 4: The technologist will go out of the room to run the scanner from a computer located directly next to the scanner suite, visible through the viewing window. At this time the CT table you are on will move into the scanner and the technologist will take the images. The actual time you are in the scanner varies based on the exam but for most patients it is around 10 - 30 minutes.

Step 5: After the exam, your images will be electronically sent to one of our radiologists who will review the information and write a report for your provider. This information is shared with your provider within 24 hours of your exam. The provider who referred you for the CT will be the one to follow-up with you about your results.
