CT Stone Protocol

A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create image slices of the bones, blood vessels and soft tissue inside your body. CT scan images provide more detailed information than plain X-rays do.

Depending on what your doctor is looking for, this test may be ordered with or without IV contrast.

What are Intravenous Contrast (IV) Media?

In order to see the blood vessels and body tissues on the scan, the technologist must inject contrast media into a vein. Some people refer to this as "dye" although it's not like the dye you might use at home. These contrast media are liquid solutions that contain iodine and show up on X-rays. It is removed from the body through the kidneys, but will not change the color of your urine.

What to Expect

This is a non-invasive exam.
During the exam you will be placed on a table and positioned inside the center of a large ring-like scanner. The machine makes a minimal amount of noise and the table moves forward and backward. The study is not painful.
You may be asked to remove jewelry, glasses, and any metal objects that may interfere with the images.
If your doctor ordered IV contrast, the technologist will start an IV in a vein in your arm. The contrast will be injected through the IV and may make you feel warm or flushed.
Please allow 30 minutes from registration to completion of test.
