Computed Tomography (CT) is a radiology procedure that combines x-rays and computer technology. The images appear as slices (like a loaf of bread) that construct images free of the superimposition of other organs and tissues. The result is a more detailed picture that may show problems with soft tissues, organs, and bones. There isradiation exposure from the CT, however the benefits provided far outweigh any risk.
The preparation for a CT examination is very simple, however, please follow instructions carefully to ensure that the test can be completed as planned. You may need to change your diet prior to the scan or drink a barium product that will help to provide contrast in the images. You may be required to obtain a special blood test to assure that your kidney function is adequate for procedures requiring an injection of intravenous (IV) iodine solution. For your safety, please inform your doctor and the technologist about any of the following:
Allergies, kidney problems, diabetic medication and if you are pregnant.
The CT procedure takes about 30 minutes, often even less depending on the area of the body to be scanned. You will be asked to lie on a x-ray table that slides into a short doughnut shaped hole. You will be required to hold your breath for a few seconds during the scan. You may have to wait a short time to make sure that the images acquired are adequate.
After your scan, you may return to your normal diet and activities. Any contrast material you were given will pass naturally through your body within a day.
Your doctor will contact you with results.
