Holding still during the scan results in the best CT pictures. For the first few scans, the table will move quickly through the scanner. These first scans check the correct starting position. The table will move more slowly for the rest of the scans. If you are having contrast, it will be given to you through your IV. A CT neck scan can take up to 15 minutes. All images will be checked for quality before you leave. More scans will be taken, if needed. What will I feel during the scan? CT scanning is painless, but you may feel some discomfort from staying still on the scan table. If contrast is used: You may notice a warm, flushed feeling during the injection.

What will I feel during the scan? CT scanning causes no pain, just as a routine X-ray is painless. If intravenous contrast is used, you may feel warm and flush and get a metallic taste in your mouth. These sensations normally disappear after a few minutes. How long will the scan take? The time required will depend upon the type of scan. If oral contrast is required, about 45 to 60 minutes is needed for the contrast to move through your digestive tract. Actual scan times vary from a few seconds to several minutes. If no oral contrast is required, the examination will take about 15 to 30 minutes, including the time for intravenous preparation and interview. In some cases additional scanning is required as scans are tailored to suit individual diagnostic needs.
