FAQs about PET Scan for Pre-surgical Assessment in Chandigarh CHD
What is a PET scan and why is it used for pre-surgical assessment?
A PET scan, or Positron Emission Tomography scan, is a type of imaging test that helps to show how your tissues and organs are functioning. When used for pre-surgical assessments, a PET scan can provide detailed information about cancerous growths or other abnormalities, which aids surgeons in planning the best approach for treatment. This imaging technique uses a small amount of radioactive material to create images that can help detect early signs of diseases, assess the effectiveness of treatments, and monitor the status of diseases, ensuring a comprehensive evaluation before surgery.
How should I prepare for my PET scan?
Preparation for a PET scan is crucial for accurate results. Typically, you will be asked to fast for at least 6 hours before your appointment. It is important to avoid strenuous exercise for 24 hours prior to the scan. If you're diabetic, consult with your healthcare provider about how to manage your blood sugar levels on the day of the test. Additionally, inform your doctor about any medications you're taking, as some may affect the results of the scan.
What happens during the PET scan procedure?
During a PET scan, a small amount of radioactive tracer is injected into your vein, usually in your arm. After the injection, you will wait for about 30 to 60 minutes to allow your body to absorb the tracer. The actual scanning process will then take approximately 20 to 30 minutes, during which you will lie on a table that slides into the PET scanner, which looks similar to a CT scanner. It's essential to stay still during the scan to get clear images. The procedure is painless, and patients usually can resume normal activities shortly afterward.
Are PET scans safe and how often can I have one?
PET scans are considered safe, and the amount of radiation exposure is minimal and lower than that received from other imaging tests like CT scans. However, they are not typically recommended for frequent use unless clinically indicated due to the cumulative exposure to radiation. Your physician will determine if and when it's appropriate for you to undergo a PET scan based on your medical history and current health condition.
How soon will I receive my PET scan results?
The time it takes to receive your PET scan results can vary. Typically, your doctor will have preliminary results within a few hours of the scan, but a comprehensive interpretation from a specialist may take a day or two. Your physician will discuss the findings with you in detail, explaining what the results mean for your condition and any further steps either before or after your surgery.
