1. Understanding PET Scans: The Basics
A Positron Emission Tomography (PET) scan is an advanced imaging technique used to visualize the metabolic activity of cells in the body. Unlike X-rays or CT scans that primarily show structure, PET scans reveal how organs and tissues are functioning at a cellular level. This makes them invaluable for diagnosing and monitoring various conditions, including cancer, heart disease, and neurological disorders.
1.1 What PET Scans Reveal
PET scans use radioactive tracers, often referred to as radiopharmaceuticals, which are injected into the bloodstream. These tracers emit positrons, which interact with electrons in the body, producing gamma rays that are detected by the PET scanner. The scanner then creates detailed 3D images, highlighting areas of high metabolic activity.
1.2 Common Uses of PET Scans
PET scans are frequently used to:
- Detect Cancer: Identify cancerous tumors and determine if cancer has spread (metastasized) to other parts of the body.
- Assess Heart Function: Evaluate blood flow to the heart and identify damaged heart tissue.
- Diagnose Brain Disorders: Detect changes in brain activity related to conditions like Alzheimer’s disease, Parkinson’s disease, and epilepsy.
- Evaluate Treatment Response: Monitor how well a patient is responding to cancer treatment or other therapies.
