What is a CT Scan?
Preparing for your scan
Prepare for your CT scan by wearing clothing free of metal in the region being scanned. You may also be asked to remove jewelry, hairpins, hearing aids, removable dental work, body piercings, or any other metal in the region being scanned. You may be asked to refrain from drinking or eating anything 1 hour or longer before your exam. Women should inform their physician or the technologist if there is a chance of pregnancy.
Allowing for paperwork and patient care time, the entire process will take an average of 40 minutes. In most cases the actual time to obtain the CT images can be done in 10 to 30 seconds. The quick scan time allows us to gather information without the chance of voluntary or involuntary motion, which can degrade the images.
