What To Expect During the CT Scan of Your Chest
After checking in, a technologist will go over the plan and position you on the CT table. You will typically lie on your back while the table moves through the scanner.
During image acquisition, you may be asked to hold your breath briefly. Remaining still and following these breathing instructions helps produce sharper images of the lungs and other structures.
If IV contrast is part of your exam, the technologist will place an IV and administer the contrast during the scan. You may briefly feel warm or notice an unusual taste when the contrast is injected.
The imaging portion of a chest CT is usually completed within several minutes. Your appointment may take longer if contrast or additional preparation is required.
