What Should I Do the Night Before a Pet Scan?

A positron emission tomography (PET) scan is a diagnostic imaging technique used to detect diseases and abnormalities in the body. It is an important tool in the diagnosis and monitoring of various conditions, including cancer, neurological disorders, and heart disease. If you have a PET scan scheduled for the next day, here are a few things you should do the night before to ensure a successful and accurate scan:

1. Review the preparation instructions: Your healthcare provider will provide you with specific instructions on how to prepare for the PET scan. It is essential to review these instructions carefully and follow them precisely. This may include avoiding certain foods and medications before the scan.

2. Avoid strenuous exercise: Engaging in intense physical activity the night before a PET scan can affect the results. It is advisable to refrain from rigorous exercise or any strenuous activities that could elevate your heart rate or metabolism.

3. Follow fasting instructions: PET scans often require fasting for a specific period before the procedure. Typically, you will be advised to avoid eating or drinking anything, except water, for at least 4-6 hours before the scan. Make sure to adhere to these fasting instructions to ensure accurate results.

4. Stay hydrated: While fasting is necessary, it is important to stay hydrated by drinking plenty of water. Hydration helps optimize the flow of blood and urine, which aids in the elimination of the radioactive tracer used during the scan.

5. Dress comfortably: Wear loose-fitting, comfortable clothing on the day of the scan. Avoid wearing jewelry, metal accessories, or clothing with zippers, as they may interfere with the scan.

6. Arrange transportation: Depending on the sedation used during the scan, you may not be able to drive afterward. It is recommended to arrange for someone to drive you home following the procedure.

7. Relax and get a good night’s sleep: It is normal to feel anxious before a PET scan. Try to relax and get a good night’s sleep to ensure you are well-rested and calm for the procedure. Adequate rest will also help you stay still during the scan, reducing the chances of motion artifacts.
