Description
An FDG PET scan, also known as a Fluorodeoxyglucose Positron Emission Tomography scan, is an advanced medical imaging test used to diagnose, stage, and monitor a wide range of diseases, especially cancer. FDG is a radioactive form of glucose that is injected into the body to highlight areas of increased metabolic activity.
Because cancer cells consume more glucose than normal cells, they absorb more FDG. The PET scanner detects radiation emitted by this tracer and creates detailed, three-dimensional images of tissues and organs, helping doctors locate and evaluate abnormal cell growth.
What Is an FDG PET Scan?
An FDG PET scan is a type of molecular imaging that shows how tissues are functioning rather than just how they look. It is widely used in oncology, cardiology, and neurology to identify disease, determine severity, and monitor response to treatment.
Why Is an FDG PET Scan Performed?
An FDG PET scan is recommended to:
- Detect and stage cancer
- Identify cancer recurrence
- Evaluate response to chemotherapy or radiation therapy
- Differentiate active disease from scar tissue
- Assess brain and heart conditions
How Is an FDG PET Scan Performed?
A small amount of FDG radiotracer is injected into a vein. After a short resting period to allow the tracer to distribute throughout the body, the patient lies on the PET scanner bed while images are taken.
The scan is painless and usually takes about 30 to 60 minutes.
Advantages of FDG PET Scan
- Highly sensitive detection of cancer and abnormal metabolism
- Provides functional and metabolic information
- Helps in accurate diagnosis and treatment planning
- Non-invasive and safe
