Positron emission tomography (PET) scanning using [18F] fluorodeoxyglucose (FDG) is a key tool in oncology. This article introduces FDG-PET imaging concepts and demonstrates its clinical applications for cancer patients.
Area of Science:
- Nuclear Medicine
- Radiochemistry
- Medical Imaging
Background:
- Positron emission tomography (PET) has evolved over 25 years.
- FDG-PET imaging utilizes the radiotracer [18F] fluorodeoxyglucose.
- Its primary application is in oncology patient evaluation.
Observation:
- FDG uptake reflects metabolic activity.
- Cancer cells often exhibit increased glucose metabolism.
- PET scans visualize areas of high FDG uptake.
Findings:
- FDG-PET provides functional imaging data.
- It aids in cancer diagnosis, staging, and treatment monitoring.
- The technique offers valuable insights into tumor biology.
Implications:
- FDG-PET enhances diagnostic accuracy in oncology.
- It supports personalized treatment strategies.
- Continued development promises broader clinical utility.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
