18-F Fluorodeoxyglucose (FDG) PET-CT Scan
For this scan, you receive an injection of a small amount of radioactive material in a form of radioactive sugar, which is called a tracer. The tracer flows in your bloodstream and collects in certain tissues or organs. Body cells take in different amounts of the sugar, depending on how fast they are growing. Cancer cells, which grow quickly, are more likely to take up larger amounts of the sugar than normal cells. Then, the PET-CT Scanner detects and makes 3D pictures that show where the tracer collects in the body.
In clinical practice, FDG PET-CT Scan is commonly used in the evaluation and management of many types of cancer, including but not limited to:
- Tumour Diagnosis
- Staging and Restaging
- Treatment Monitoring to access the effectiveness of a treatment plan
- Radiation Therapy Planning
Oncology imaging with PET has recently gained particular importance in the quest to identify new and effective therapies and to understand the role of molecular biomarkers in treating cancer.
