What to Expect

You will be comfortably positioned on a CT table, and you may be supported by pillows to help you stay in the proper position during the procedure. The table will move slowly into the opening of the CT scanner. Very small amounts of x-ray radiation will pass through your body. A CT examination usually takes between 15-30 minutes.

Depending on your exam, a contrast material may be injected into a vein to enhance the visibility of blood vessels and kidneys, and to accentuate the appearance between normal and abnormal tissue in organs such as the liver and spleen. Some people report feeling a flush of heat or a metallic taste in the back of the mouth. These sensations usually disappear within a minute or two. Side effects are rare, and registered nurses will be available throughout your procedure.

How to Prepare

Arrive 15 minute prior to exam. Wear comfortable, loose-fitting clothing, without zippers or snaps. You may be asked not to eat or drink anything for up to 4 hours before the exam and to avoid caffeine and smoking for at least 4 hours prior to the exam to keep your heart rate down. Women should inform the technologist if there is any possibility that they are pregnant. Patient lockers are available for jewelry and other valuable items; however, you are encouraged to leave all jewelry at home during procedures.
