Frequently Asked Questions
What does a CT scanner look like?
The CT scanner looks like a large doughnut 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 about a quart of liquid prior to the scan. For certain
exams, x-ray contrast also 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 four hours before the exam. You
should however take all your medications with a sip of water at
the regular time.
More about preparing for the exam.
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.
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.
