A pet scan is a special imaging procedure used to detect cancer by looking at how the body uses glucose. In preparation for a pet scan, you will need to follow a low-carbohydrate diet for 24-48 hours beforehand. This will help ensure that the glucose you consume is used by the cancer cells, making them easier to detect.

What You Can Eat the Day Before a Pet Scan

Here are some foods that you can eat the day before a pet scan:

  • Lean protein, such as chicken, fish, and tofu
  • Vegetables, such as broccoli, cauliflower, and lettuce
  • Fruits, such as berries and apples
  • Whole grains, such as brown rice and quinoa
  • Healthy fats, such as olive oil and avocado

Foods to Avoid

Here are some foods that you should avoid the day before a pet scan:

  • Fried foods, such as french fries and onion rings
  • Processed foods, such as chips and cookies
  • Red meat, such as beef and pork

Other Tips

In addition to following a low-carbohydrate diet, there are a few other things you can do to prepare for a pet scan:

  • Drink plenty of fluids in the hours leading up to your scan. This will help to flush out any excess glucose from your body.
  • Avoid caffeine and alcohol for 24 hours before your scan. These substances can interfere with the accuracy of the scan.
