What Is a PET Scan?
A PET scan is an imaging test that helps doctors diagnose and monitor conditions like cancer, heart problems, and brain disorders. Unlike standard imaging techniques, it provides detailed insights into how your organs and tissues function. The test uses a small amount of radioactive tracer to highlight areas of concern.
Before we dive into preparation, let’s touch on a common question: how much does a PET CT scan cost? The pet ct scan price varies depending on the location and facility. Understanding the cost can help you plan better for the procedure.
Dos: What You Should Do Before a PET Scan
- Follow Fasting Instructions
Most PET scans require fasting for 4–6 hours before the procedure. This is because eating can affect the results, especially if the scan is focused on metabolic activity. Stick to the fasting instructions provided by your doctor.
Example: Priya, a 42-year-old cancer survivor, shared how she once forgot to fast before her first PET scan. The results were inconclusive, and she had to reschedule, causing unnecessary stress. Learning from this, she double-checked her prep list for her next scan. - Stay Hydrated
Drinking water is usually encouraged unless your doctor says otherwise. Staying hydrated helps flush out the radioactive tracer after the scan. - Inform Your Doctor About Medications
Certain medications can interfere with the scan. Let your doctor know about any prescriptions, supplements, or over-the-counter medicines you’re taking. - Dress Comfortably
Wear loose, comfortable clothing without metal components like zippers or buttons. Metal can interfere with the scan results. - Bring Relevant Documents
Carry your doctor’s referral, previous scan reports, and ID proof. Being prepared ensures a smooth check-in process.

Sugar and carbs can interfere with how the tracer interacts with your body. Stick to the diet plan prescribed by your doctor. - Avoid Caffeine and Tobacco
Both caffeine and tobacco can impact the scan results. Refrain from coffee, tea, or smoking for at least 24 hours before the procedure. - Don’t Ignore Allergies or Medical Conditions
If you’re allergic to any medications or have conditions like diabetes, inform your healthcare provider. They may need to adjust the preparation steps.
