Description
FDG PET and Choline PET are two advanced types of Positron Emission Tomography (PET) scans that use different radioactive tracers to detect disease at the cellular level. FDG PET uses Fluorodeoxyglucose (FDG), a glucose-based tracer, while Choline PET uses a Choline-based radiotracer. Each tracer highlights different biological processes, making them useful for different types of cancers and medical conditions.
Because various diseases behave differently at the cellular level, FDG PET and Choline PET provide complementary information that helps doctors choose the most accurate imaging method.
What Is FDG PET?
FDG PET measures how much glucose is used by cells. Since cancer cells consume more glucose than normal cells, FDG PET is widely used to detect, stage, and monitor many types of cancer, as well as infections and inflammatory conditions.
What Is Choline PET?
Choline PET evaluates cell membrane metabolism. It is especially useful for detecting and staging prostate cancer and certain other tumors that may not be clearly visible on FDG PET scans.
Why Are FDG PET and Choline PET Performed?
These scans are used to:
- Detect and stage cancer
- Identify cancer recurrence
- Assess treatment response
- Differentiate active disease from scar tissue
- Guide radiation and surgical planning
How Are FDG PET and Choline PET Performed?
A small amount of radioactive tracer, either FDG or Choline, is injected into a vein. After a short waiting period to allow the tracer to be absorbed by active cells, the patient lies on the PET scanner while images are taken.
The scan is painless and typically takes 30 to 60 minutes.
Advantages of FDG PET and Choline PET
- Highly sensitive detection of cancer and abnormal cell activity
- Provides functional information beyond conventional imaging
- Helps in accurate staging and treatment planning
- Non-invasive and safe
