What Is a PET Scan?
A Positron Emission Tomography (PET) scan is an advanced imaging technique used to observe metabolic processes in the body. By detecting radioactive tracers, PET scans help doctors diagnose diseases like cancer, heart conditions, and neurological disorders.
How Does a PET Scan Work?
The PET scan works by injecting a small amount of a radioactive substance (like FDG) into the body. This tracer emits positrons, which interact with electrons in the body, creating gamma rays captured by the scanner to create detailed images of organs and tissues.
What Is FDG in a PET Scan?
Fluorodeoxyglucose (FDG) is the most commonly used radioactive tracer in PET scans. It mimics glucose and highlights areas with high metabolic activity, often indicating the presence of tumors or inflammation.
The PET Scan Procedure: Step-by-Step Guide
- Consultation: Discuss your medical history and symptoms with your doctor.
- Preparation: Follow fasting guidelines and avoid certain medications.
- Tracer Injection: FDG is injected into your bloodstream.
- Waiting Period: Allow the tracer to circulate (typically 30-60 minutes).
- Scanning: Lie still as the scanner captures images.
- Completion: Results are interpreted by a radiologist.
Preparation for a PET Scan
- Fast for at least 6 hours before the scan.
- Avoid strenuous exercise 24 hours prior.
- Inform your doctor about any medications or allergies.
What to Expect During a PET Scan
You’ll lie on a table that slides into the PET scanner. The procedure is painless, but staying still is crucial for clear images.
After the PET Scan: Results and Recovery
- Drink plenty of water to flush the tracer from your system.
- Resume normal activities unless instructed otherwise.
- Results are usually available within a few days.
Difference Between PET Scan, CT Scan, and MRI Scan
| Feature | PET Scan | CT Scan | MRI Scan |
|---|---|---|---|
| Imaging Type | Metabolic | Structural | Soft tissues |
| Radiation | Yes | Yes | No |
| Tracer Usage | Yes (Radioactive) | No | No |
| Time Required | 30-60 min | 5-10 min | 30-60 min |
What Is a PET-CT Scan?
A PET-CT scan combines metabolic imaging from a PET scan with the structural detail of a CT scan, offering a more comprehensive diagnostic picture.
Applications of PET Scans in Medical Diagnosis
- Cancer detection and staging
- Assessing heart health
- Identifying neurological conditions like Alzheimer’s
Benefits and Risks of PET Scans
Benefits:
- Early disease detection
- Accurate treatment planning
Risks:
- Exposure to low-level radiation
- Allergic reactions to the tracer (rare)
Cost of a PET Scan in India
PET scan costs vary based on the type and location but generally range between ₹15,000 and ₹25,000.
Choosing the Right Diagnostic Center for PET Scans
Look for:
- Certified radiologists
- Modern equipment
- Patient-friendly services
