CT Scan Patient Prep Info

What is Computed Tomography?

Computed Tomography (CT), also known as computerized tomography or computed axial tomography (CAT), is an advanced x-ray technology that produces a sequence of detailed cross-sectional images of the interior of the head, spine, chest, abdomen or other areas of the body. The complex images are produced by rotating a focused x-ray beam around the patient and taking these x-ray images from numerous angles, guided by a computer. CT examinations produce detailed organ studies by capturing multiple individual image "slices".  For more information on this and other radiology procedures, please visit www.radiologyinfo.org.

How do I prepare for a CT Exam?

If you are having a CT of the abdomen or pelvis, we will ask you to make arrangements to obtain the oral CT contrast from our office in advance of your appointment so you may drink this before arriving at the office on the day of your appointment Do not eat solid foods 4 hours prior to the exam. Clear liquids and medications are allowed up to 2 hours before the exam.

What should I expect?

For your CT examination you will be asked to lie on a table that rides on a track through the doughnut-shaped scanner. As the procedure begins, you will hear humming, buzzing or clicking sounds from the CT machine. The table will move in short steps or in one continuous movement through the scanner as the CT tube rotates around you. At each step, the scanner completes a separate view or a helical scan may be obtained in one breath hold. The information is processed by the computer and displayed as images on a video screen to the technologist.

You should remain as still as possible to produce the clearest images. Depending upon the procedure being performed, you may be asked to hold your breath for up to 30 seconds. Most exams require 15 to 45 minutes to complete.

After your procedure, your physician will receive a detailed report, and he or she will be the one to give those results to you.

Lowest Radiation Dose CT
