What To Think About
computed tomography (CT) scan may be needed to check
any problems found on a facial X-ray. CT scans are better than X-rays for some
problems, such as severe facial trauma or sinusitis. CT scans are more
expensive than facial X-rays and may not be available in some areas. Facial and
sinus X-rays may be done if a CT scan is not available. For more information,
see the topic
Computed Tomography (CT) Scan of the Head and Face.
Your X-ray results may be different from earlier test results
because you were tested at a different medical center or you had a different
kind of test.
