What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- If you can't remain still during the test. The pictures may not be clear.
- If you have a possible neck injury. In this case, it may not be possible to do a complete set of skull X-rays.
- If you have a false eye (prosthetic eye) or other artificial or metal objects on the head. These can make a shadow on the X-ray picture that hides part of the bones.
What To Think About
- A computed tomography (CT) scan may be done instead of a skull X-ray. A CT scan shows more detail than an X-ray does. It may show tiny fractures better than an X-ray and can also show injuries to the brain and other tissues. CT scans are more expensive than skull X-rays and may not be available in some areas. To learn more, 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.
