Computed Tomography
(CT or "CAT" Scan)
- What is a CT scan?
CT or "CAT" scans are special x-ray tests that produce
cross-sectional images of the body using x-rays and a computer. These
images allow the radiologist to look at the inside of the body.
 What does a CT scanner look like?
This is a picture of a CT scanner. The CT scanner looks like a large
donut with a narrow table. The patient lies on the table which moves
through the center of the machine. The technologist is in the next room
and observes the patient through a large window.
- Do I have to do anything special before having a CT scan?
Some scans (abdomen and pelvis) require the patient to drink a special
liquid prior to the scan. Also, for certain exams, x-ray contrast
may be injected into a vein during the scan. If you are scheduled to have
a test with intravenous contrast, you should not eat for 4 hours before
the exam. You should however take all your medications with a sip of water
at the regular time.
Specific eating/drinking preparations
Because a child needs to hold still during the scanning, younger
children and infants may need sedation for their exam. Arrangements
for sedation will be made in advance, and you will receive
instructions from the staff regarding preparation.
- How long does a CT scan take?
The entire procedure takes 15 to 45 minutes depending on what part of
the body is being scanned. After the scan is finished, one of our board
certified radiologists will interpret the study and send a report to your
doctor within 24 hours.
- Will it hurt?
No. The scanner uses x-rays to see inside your body.
- When may I eat after the test?
As soon as the exam is over.
- How will I get the results of the CT scan?
After the scan is finished, one of our board certified radiologists
will interpret the study and send a report to your doctor within 24 hours.
