My doctor wants to perform a CAT scan on me. What is the procedure like?

The procedure is usually performed in an outpatient setting and takes about 30 minutes. You will be asked to lie on your back with your head secured in a comfortable position. A technician will then insert a small tube into your mouth and down your throat, which allows them to move around your chest and abdomen. They will then take X-rays of your chest, stomach, liver, kidneys, and other organs. After the images are taken, you will be given contrast material to drink so that the doctors can see better what's going on inside your body. Finally, they will remove the tube from your mouth and you'll be free to go.
