CT Scan

What is CT?

Computed Tomography (CT), also known as CAT scan, 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 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.


Low-dose imaging for your protection

X-ray and CT exams require some radiation to generate an image. Physicians use these images to diagnose and treat diseases and injuries. Bryan Health's new imaging systems have low-dose features to protect patients from unnecessary radiation dose. We've invested in new technology and are following industry-best procedures to ensure our patients receive the lowest radiation dose possible and the highest quality image.

  CT Scan

What does the CT scanner look like?

The CT scanner has a large, short opening in which a table moves up and slowly through. Most of the patient's body will be outside of the opening as a scan is being done. As the patient moves through the large opening, an x-ray tube rotates around the patient obtaining images, which are then sent to a computer for interpretation.

 


How should I come prepared for my CT?

Clothing should be free of metal in the region being scanned. For example, for scanning of the chest, shirts should have no metal buttons and bras should have no metal clips or clasps. For scanning of the pelvis, pants should not have zippers or metal buttons. 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. Correct attire is available with private changing rooms and secured lockers. You may also be asked to refrain from drinking or eating anything one hour or longer before your exam. Women should inform their physician or the technologist if there is a chance of pregnancy.

 

How long will my CT examination take?

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.
