Why is a Low Carb Diet Necessary Before a PET Scan?

PET imaging is a diagnostic imaging tool that can assess areas of abnormal glucose metabolism in the body. It is a process by which images of the body's biological functions can be obtained by using a small amount of a biological marker. After the PET procedure, a doctor will review the images and soon after, you will be informed of the results. It is important to follow a low carb diet before undergoing a PET scan in order to ensure that your images are of the best quality. Eating too many carbohydrates can lead to high blood sugar levels, which can interfere with the accuracy of the scan.

By following a low carb diet, you can avoid having to reschedule the scan due to too high blood sugar. If you are scheduled for a PET scan, it is important to follow your doctor's instructions regarding diet and other pre-scan preparations. This will help ensure that your scan results are accurate and that you get the best possible outcome from your procedure.
