FAQs about CT Scans
Why is CT important?
CT scans allow doctors to see images of your internal organs and
structures in great detail from a variety of angles. This gives your physicians
critical information more quickly and, in many cases, more economically than
they could achieve with other tests or invasive techniques. In those cases
where surgery is recommended, the information from the CT scan helps the
surgical team in the planning process.
Is CT like an X-ray?
Yes. CT uses X-rays in conjunction with advanced computer technology
to generate very accurate and detailed images of your internal organs, and
structures. Your technologist will step into a control room to conduct the
actual exam. You may notice a mechanical noise coming from the scanner. This is
just the X-ray tube being activated and rotating around your body.
Will the CT scan hurt?
No. CT is a painless, non-invasive test that will not hurt at
all. Your exam might require that a contrast agent be given intravenously that
will make your blood vessels and tissues more visible. You will then be asked
to lie perfectly still once the technologist has positioned you appropriately
on the table. You may also be asked to hold your breath for a few seconds
during the exam. Any movement might require the exam to be repeated.
How long will my CT exam take?
The length of your CT exam depends on which particular study, or
studies, your doctor has ordered. Most exams are quick and painless, lasting
just a few minutes. You may be asked to arrive at the facility 15 or 30 minutes
prior to your scheduled exam time.
Do I have to do anything special to prepare for my CT scan?
How you prepare for your CT scan depends on what part of the
body is being examined and the protocols used in your particular facility. In
some cases the staff may ask you to change into a hospital gown for the exam.
And you may be asked not to eat or drink anything before your exam.
What is a contrast agent?
A contrast agent is a liquid substance that makes certain
tissues stand out more clearly against their surroundings, enabling the finest
details to show up on the X-ray, improving diagnostic accuracy. You may be
given the contrast agent intravenously or orally. In all cases the contrast
agent will leave your body naturally within a few hours. If your exam does
require a contrast agent, be sure to tell the technologist if you have any
allergies, especially to iodine or shellfish.
How long will it take to get my results?
The CT scans take just a few minutes. The time the doctor takes
to review the results varies. However, in most cases, you will receive results
soon after your scan. Check with your doctor for a more precise estimate.
What parts of the body can a Brilliance CT scanner evaluate?
Almost all of it, since CT scans are used to view both soft and
hard tissue.
Will I feel claustrophobic?
Our state-of-the-art CT system is specifically designed to
provide the ultimate in patient comfort including a more open design which
allows patients to see outside of the machine during examinations, reducing claustrophobic
effects. This more open unobstructed view offers greater comfort than
conventional “tube shaped” machines and also allows you to see and talk to your
technologist during your exam.
Are there any people who shouldn’t get CT scans?
If you are pregnant, think you might be pregnant, or have
allergies, you should inform your doctor and CT technician prior to your exam.
Can my family be present during the exam?
Typically, family members and/or friends are not permitted to
stay with you in the CT room. However, these rules are different at some
facilities and for some types of patients.
Will I be alone during the CT exam?
During your CT exam, you will be in contact with a technologist.
Even when the technologist is not in the CT room you will be able to
communicate via intercom. The technologist will inform you when an exam is
about to start and when it is finished.
