Preparing for Your PET Scan: What to Eat and Avoid on Your Diet Beforehand


So, you’ve been scheduled for a PET scan. It’s a diagnostic test that uses a special dye and a camera to create images of organs and tissues inside your body. But before you head over to the medical center, it’s important to know what to eat and avoid on your diet beforehand to ensure accurate results. Here’s a rundown:

What to Eat:

1. Water – Drink plenty of water to help flush out any toxins in your body and to help prevent dehydration during the test.

2. Low-carb foods – Eat foods that are low in carbohydrates such as vegetables, lean proteins, and healthy fats. This is because the PET scan detects glucose uptake in your body, and high-carb foods can interfere with the results.

3. Foods high in protein – Eating foods high in protein can help keep you feeling full and satisfied, which is especially important if you have to fast before your test.

What to Avoid:

1. Sugar – Avoid foods that are high in sugar or simple carbohydrates such as candy, soda, and baked goods. These foods can raise your blood sugar levels and interfere with the accuracy of the test.

2. Caffeine – Avoid caffeine-containing foods and beverages such as coffee, tea, and chocolate. Caffeine can affect your body’s metabolism and may interfere with the results of the test.

3. Alcohol – Avoid alcohol for at least 24 hours before your test. Alcohol can affect your body’s metabolism and may interfere with the accuracy of the test.

Remember to always follow your doctor’s instructions when preparing for your PET scan. By eating the right foods and avoiding certain foods, you can help ensure accurate results and a successful test.
