Computed Tomography (CT)
Computed Tomography (CT) also known as CT or a CAT scan, is a type of x-ray
that provides detailed, cross-sectional (sliced) images of the body. A
primary advantage of CT imaging is that it can be done on all types of
body tissue (such as muscle and bone) without sacrificing clarity.
A special dye, also known as contrast or iodine, may be used during your
exam, to highlight your blood vessels and organs. This will provide more
detailed information to your doctor.
Please notify the technologist if you are allergic to Iodine, or think
you may be.
Women should always inform their doctor or technologist if there is any
possibility that they are pregnant.
