What is a CT scan?

A CT or CAT scan, also known as a computed tomography scan, is a medical imaging method that uses special X-ray equipment to obtain cross-sectional pictures of the body. The CT computer displays these pictures as detailed images of organs, bones, and other tissues. This type of imaging can be very helpful in diagnosing injuries or fractures or in identifying disease in its earliest stages.

What happens during my exam?

You’ll be asked to change into a gown and then you will lie down on a patient table. The CT system is shaped like a large doughnut and the center of it is called the gantry. The patient table will move slowly through the gantry. Once the table and you are in the correct position, your CT technologist may ask you to hold your breath or not to move. You’ll hear the CT system, which makes a low whirring sound.

What is a CT scan with contrast?

For some CT examinations, a contrast medium (sometimes called a dye) is given to help highlight a particular area of your body. Depending on the type of exam, contrast medium is administered in a number of different ways. You might, for example, be asked to drink it or it might be injected into a vein. Keep in mind the contrast medium contains iodine, which can cause an allergic reaction in some people. Please consult your physician regarding any existing allergies prior to the examination or any question regarding contrast medium.

Are there risks associated with a CT scan?

CT scans use X-rays, invisible beams of ionizing radiation that pass through the body and are altered by different tissues to create images. A very small percentage of patients may have an allergic reaction to IV contrast containing iodine. Although reactions are very rare, please inform your physician and imaging staff if you are allergic to iodine or IV contrast.
