An orbital CT scan is a procedure that uses x-rays to examine the orbits (the eye sockets) and the globes (the eyes).
Alternative Names:
CT scan - orbital
How the test is performed:
A contrast dye may be injected into a vein before the test.
You lie on a table that can be moved by the technician operating the scanner. Only your head is positioned inside the CT scanner. The exam usually lasts no more than a few minutes.
You may be allowed to rest your head on a pillow, but this must be done before the scan begins. It is very important that once your head is in place, you do not move it during the test
How to prepare for the test:
You must sign an informed consent form. Remove dentures, any jewelry, and anything metal.
How the test will feel:
The most discomfort arises from the need to lie still on the table during the scan. The scan itself is painless.
