Computed-tomography (CT) scan is a special type of X-ray that provides a more detailed view of organs, blood vessels, bones and soft tissue than regular X-rays. Mahaska Health’s CT scanner uses the lowest possible radiation dose to provide the most detailed scans. In addition, the system is much faster, allowing us to capture images from a larger area in a shorter amount of time; usually only requiring a seven second breath hold.
Preparing for a CT
Your healthcare provider will give you a list of instructions to follow for your particular exam type. If you are having a scan of the abdominal or pelvic area, you might be asked to drink a contrast beverage the night before and 1 to 2 hours prior to the exam. The oral contrast has a vanilla flavor, and most patients do not find it unpleasant.
You may have to arrive before your scan to have blood drawn to check the functioning of your kidneys. Well functioning kidneys are necessary to help filter and excrete the IV contrast that may be used in your exam.
Clothing
Depending on the type of scan you are having, you may be asked to change into a gown. In some cases, you may be able to wear your regular clothing, so we encourage you to wear loose-fitting, comfortable clothes that have no metal.
Scanning
A technologist will position you on the examination table. Once in position, you will be moved through a doughnut shaped ring, which is the scanner. Patients can expect the entire CT process to take from 30 to 90 minutes.
Occasionally, patients may experience an allergic reaction to the contrast. Let the technologist know in advance if you have any known allergies to iodine, or if you experience any itching, rash, hives or difficulties with breathing or swallowing during the scan. Also inform the technologist if you have kidney problems, any diabetes medications you are taking, and if you are pregnant or think you may be before any contrast is administered.
After the scan, you can return to your normal activities and routine diet right away.
