PET Scan: Process, Costs, Uses, and Cancer Detection

If you or a loved one has been advised to get a PET scan, it’s natural to have questions about what it is, how it works, and what to expect. A PET scan is a powerful imaging test that helps doctors detect cancer, heart problems, and brain conditions at an early stage, often before symptoms appear. Knowing the process, costs, and preparation steps can make things easier and reduce stress. This guide will provide you with clear and simple information to help you understand everything you need to know about PET scans, so you can make informed decisions for your health.

What is a PET Scan? 

A Positron Emission Tomography (PET) scan is a medical imaging test that helps doctors see how your tissues and organs are functioning. It uses a small amount of radioactive material, known as a tracer, to detect changes at the cellular level. This can help identify diseases before they become apparent on other imaging tests.

How Does a PET Scan Work? – Process & Procedure

• Tracer Injection: A radioactive substance (tracer) is injected into your bloodstream.

• Absorption Period: Your body needs time to absorb the tracer, usually about an hour.

• Scanning: You lie on a table that slides into a large, tunnel-shaped scanner.

• Imaging: The scanner detects the radiation emitted by the tracer, creating images of your internal organs and tissues.

The entire process typically takes about two hours.

Why is a PET Scan Done? – Uses in Cancer, Heart & Brain Diseases

PET scans are valuable in diagnosing and managing various conditions:

• Cancer Detection and Management: Identifying cancerous tissues, determining the extent of cancer spread, and evaluating the effectiveness of treatments.

• Heart Disease: Assessing blood flow and identifying areas of the heart with reduced function.

• Brain Disorders: Diagnosing conditions like Alzheimer’s disease, epilepsy, and other neurological disorders.

Can a PET Scan Detect All Cancers? Accuracy & Limitations

While PET scans are highly effective in detecting many types of cancers, they may not identify all forms. Some small tumors or certain cancer types may not appear on PET scans. Additionally, non-cancerous conditions can sometimes cause false-positive results. Therefore, PET scans are often used in combination with other diagnostic tests to provide a comprehensive assessment.

PET Scan vs. CT Scan – Key Differences

• Function vs. Structure: PET scans show metabolic activity (function), while CT scans provide detailed images of anatomical structures (structure).

• Radiation Exposure: Both involve exposure to radiation, but the types and amounts differ.

• Usage: PET scans are often used to detect cancer and assess its spread, whereas CT scans are commonly used to detect bone injuries, lung and chest problems, and cancers.
