PET imaging is a diagnostic imaging tool that allows doctors to obtain images of the body's biological functions. By using a small amount of a biological marker, the PET procedure can assess areas of abnormal glucose metabolism in the body. After the scan, a doctor will review the images and inform you 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 highest quality. Eating too many carbohydrates can lead to high blood sugar levels, which can interfere with the accuracy of the scan.
If your blood sugar levels are too high, you may have to reschedule the scan. If you are scheduled for a PET scan, it is important to follow a low carb diet for at least 24 hours before the procedure. This will help ensure that your images are of the best quality and will help avoid having to reschedule the scan due to too high blood sugar.
