Computed tomography (CT) is a test that combines x-rays and computer scans. The result is a detailed picture that can show problems with soft tissues (such as the lining of your sinuses), organs (such as your kidneys or lungs), and bones.
Be sure to mention the medications you take and ask if it is okay to take them before the test.
If instructed, stop eating and drinking 8 hours before your CT.
If instructed, drink contrast (a liquid that improves the image) 8 hours before your CT.
The test may take 10 minutes to 2 hours, depending on whether contrast is used and the part of the body being scanned.
