What is a CT Scan?
Computed Tomography(CT), uses a limited beam of x-ray to obtain image data. The data is then interpreted by a computer to show cross sectional images of the body tissues and organs. Dense tissues, such as bones, appear white in the pictures produced by a CT scan. Less dense tissues, such as brain tissue or muscles, appear in shades of gray. Air-filled spaces, such as in the bowel or lungs, appear black. CT services are available 8am-5pm for routine outpatient studies and 24/7 for Emergency studies.
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.
