Computed Tomography (CT)
What is Computed Tomography?
Computed Tomography scans (also known as CT or CAT scans) use special X-ray
equipment to obtain information from different angles around the body. Computers
are then used to process the information and create cross-sectional images
that appear as "slices" of the body and organs.
What Should I Expect?
During the exam you will lie on a table that will move you into the doughnut-shaped
scanner. Your technologist will watch you through an observation window and
will be able to communicate with you at all times. You may hear humming,
buzzing, or clicking sounds as the CT machine moves to reposition you for
additional images. CT scans are painless, but some exams require injection
of a contrast agent through an IV that will be started before
the exam in either your arm or hand area by a technologist. If
you are having an abdomen and/or pelvic exam you may be required to drink
contrast fluid 30 mins-1 hour prior to exam time. Remaining
still is very important in order to obtain clear images.
How Should I Prepare?
Before some exams, you may be asked to avoid normal eating or drinking for
a period of time. You should continue medications prescribed by your doctor
unless informed otherwise. Diabetic patients may need to delay their medication
until after they have eaten in order to avoid an insulin reaction. You may
be asked to wear a hospital gown and may have to remove items such as glasses,
jewelry, dentures, hearing aids, etc. Women should always inform their technologist
if there is any possibility that they are pregnant.
What if I Need a Contrast Injection?
CT contrast is an organically bound iodine material that is used to make some
abnormalities easier to see and will be delivered through a small
IV started in you arm or hand by the technologist. KCIC uses only non-ionic
contrast (the safest kind), but with all contrast agents there is some potential
for allergic reaction. Be sure to tell your technologist if you've had a reaction
to contrast in the past or if you are particularly sensitive to medications.
If you take Glucophage, Glucovance, or any other type of metformin medication
to regulate your diabetes, you will need to stop taking it for 48 hours after
your exam.
How Do I Get the Results?
After your study is over, the images will be evaluated by one of our board-certified radiologists with expertise in CT imaging. A final report will be sent to your doctor, who can then discuss the results with you in detail. Should you have any questions regarding your CT scan, we will be happy to discuss them with you.
