Campbell County Health Radiology at Campbell County Memorial Hospital uses
CT imaging technology that enables excellent quality images using low
radiation doses in Gillette, Wyoming.
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.
