Why Can’T I Eat Or Drink before a Ct Scan

If you’re scheduled for a CT scan, you may be wondering why you can’t eat or drink before the test. After all, other imaging tests like X-rays don’t have this restriction. The reason has to do with the way CT scans are performed.

CT scans use special x-ray equipment that rotates around your body to create detailed images of your internal organs, bones and other tissues. During the scan, you’ll lie on a table that slides through the center of the x-ray machine. If you have food or liquid in your stomach when the scan starts, it will start moving along with the table as it goes through the machine.

This can cause nausea and vomiting. In some cases, it can also lead to abdominal pain or bloating.
