A whole-body PET (Positron Emission Tomography) scan is a medical imaging technique that produces detailed, 3D images of the entire body. It helps diagnose and monitor various conditions, including cancer, neurological disorders and cardiovascular disease.
1. Patient preparation: fasting, hydration and medication restrictions.
2. Tracer injection (e.g., FDG, typically 5-10 mCi).
3. Uptake period (30-60 minutes).
4. PET scan (10-30 minutes).
1. Cancer diagnosis and staging.
2. Cancer treatment monitoring.
3. Recurrence detection.
4. Neurological disorders (e.g., Alzheimer’s disease, Parkinson’s disease).
5. Cardiovascular disease (e.g., myocardial viability).
6. Infection and inflammation detection.
1. FDG (Fluorodeoxyglucose): glucose metabolism.
2. NaF (Sodium Fluoride): bone metabolism.
3. Amyloid tracers (e.g., Pittsburgh Compound-B): Alzheimer’s disease.
4. Dopamine tracers (e.g., F-DOPA): Parkinson’s disease.
1. CT: lower sensitivity for small lesions.
2. MRI: lower sensitivity for certain conditions.
3. SPECT: lower spatial resolution.
4. Ultrasound: operator-dependent, limited depth penetration.
A PET scan uses a small amount of radioactive material to visualize metabolic activity in the body, helping detect cancer and other diseases.
Yes, PET scans are considered safe; the radiation exposure is minimal and comparable to other imaging tests.
You will receive a radioactive tracer, wait for it to circulate, and then lie down in a scanner for about 20-30 minutes while images are taken.
Results are typically available within 24-48 hours, and your doctor will discuss them with you.
