What is CT Scanning of the Body?

Computed tomography, more commonly known as a CT or CAT scan, is a test that makes multiple pictures of the inside of the body.

The cross-sectional images generated during a CT scan can be made into three-dimensional images. These images can be viewed on a computer monitor, printed on film or transferred to a CD or DVD.

CT images of internal organs, bones, soft tissue and blood vessels show much more detail than traditional x-rays.

Using specialized equipment and expertise to create and interpret CT scans of the body, our highly-trained doctor can more easily diagnose problems such as cancer, cardiovascular disease, infection, inflammation, and injury.


How should I prepare?

You should wear comfortable clothing. You may be given a gown or scrubs to wear during the exam.


You may be asked not to eat or drink anything for a few hours beforehand, as IV contrast material may be used in your exam. You should inform your physician of all medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or "dye," your doctor may prescribe medications (usually a steroid) to reduce the risk of an allergic reaction. These medications generally need to be taken 12 hours prior to administration of contrast material. To avoid unnecessary delays, contact your doctor before the exact time of your exam.


Women should always inform their doctor and the CT technologist if there is any possibility that they may be pregnant. 


How is the CT scan done?

The technologist begins by positioning you on the CT examination table, usually lying flat on your back.


Next, the table will move quickly through to determine the position for the scans. Then, the table moves slowly through the machine as the actual CT scanning is performed. You may be asked to hold your breath during the scanning. The scan itself usually takes less than a few minutes to complete.


Your technologist will be available to answer any questions or address any concerns that you may have.  Feel free to call us with any questions.
