It’s usually preferred that a person not eat for three or four hours before certain CT scans. There’s a small risk of nausea and vomiting during the scan, which may be reduced if the stomach is empty. An empty stomach might also improve some of the images collected.

Check with your radiology center for specific instructions on how to prep for your CT scan.
