CT Information for Patients and Family

WHAT?

Computed Tomography (CT) uses x-rays and computers to create a realistic, 3D image. A dye is sometimes injected into your vein to reconstruct cross-sectional images of various parts of the body. The images are reviewed by a Radiologist who will use this exam to help in your diagnosis.

WHERE?

Georgian Bay General Hospital’s Diagnostic Imaging Department, located on the main level just past switchboard and in close proximity to the Emergency Department.

TIME?

Depends on the test, most are completed in approximately 15 minutes, but can range from 5-20 minutes. Emergency patients take precedence and may cause delays, however we do our best to remain on schedule.

If you are unable to keep your appointment, please notify us by telephone immediately.

DURING THE CT:

You may get an intravenous (IV) line put into a large vein in your arm. This line will be used to give you a dye (contrast) to help the procedure. When the images are acquired, you will be asked to be still and hold your breath for approximately 15 seconds. During the scan, the table will move through what looks like a large donut or ring. This is the part of the machine that scans your body takes the image. Once the technologist collects all the images, your IV will be removed. The scan will take about 15 minutes to finish.

AFTER THE CT:

If you received dye as part of your scan, you will be asked to remain in the department for 15 minutes after your scan is complete.

Results from the Radiologist will be sent to your ordering Physician to discuss with you.
