CT Scan FAQS
Q: Is CT an X-Ray?
A: Yes. A CT scan is made up of a series of X-rays which are processed by a computer to produce cross-sectional pictures of the part of the body in question. These cross-sectional images allow one to look at the inside of the body just as one would look at the inside of a loaf of bread by slicing it. A CT scan is made up of a series of slices.
Q: Do I have to go into that “tunnel”?
A: The tunnel is the opening in the CT scanner. It is a short tunnel that is open in the front and back. Since the opening contains the X-ray tube and detector which create the CT pictures, the part of your body being scanned must pass through it. For example if your head or neck is being evaluated, then your head and neck will pass through the opening. If the scan is of your abdomen, then only your lower chest down will pass through the gantry.
Q: Should I be concerned about the amount of radiation I receive?
A: Radiation safety is of paramount importance to Rhode Island Medical Imaging. Our equipment and exam protocols are regularly evaluated to ensure that the lowest amount of radiation is used that will still result in the highest quality imaging. RIMI participates in the national programs called Image Gently and Image Wisely to ensure we provide the safest exams possible.
