Positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose integrated with computed tomography (18F-FDG PET/CT) is a key imaging tool for cancer diagnosis and management. This technique aids in staging, detecting recurrence, and monitoring therapy response, influencing patient treatment in approximately 27% of cases.
Area of Science:
- Oncology
- Radiology
- Nuclear Medicine
Background:
- Accurate cancer diagnosis and staging are critical for effective patient management.
- Conventional imaging techniques have limitations in detecting certain cancer aspects.
- 18F-FDG PET/CT combines PET and CT for synergistic advantages in cancer imaging.
Purpose of the Study:
- To provide guidance on the oncologic applications of 18F-FDG PET/CT.
- To highlight the benefits of integrated PET/CT over standalone modalities.
- To inform oncologists and specialists about the utility of 18F-FDG PET/CT in clinical practice.
Main Methods:
- Review of the literature on 18F-FDG PET/CT in oncology.
- Analysis of the combined advantages of PET and CT acquisition.
- Evaluation of 18F-FDG PET/CT's role in diagnosis, staging, restaging, recurrence detection, and therapy monitoring.
Main Results:
- 18F-FDG PET/CT is a powerful tool for detecting various cancers.
- It is valuable for staging, restaging, and detecting recurrence, especially in asymptomatic patients or those with equivocal conventional imaging.
- The use of 18F-FDG PET/CT can lead to changes in patient management in about 27% of cases.
- It enables effective monitoring of treatment response, allowing for timely therapeutic modifications.
Conclusions:
- 18F-FDG PET/CT offers significant advantages in cancer management due to its combined imaging capabilities.
- Its application impacts patient care by improving diagnostic accuracy and guiding treatment decisions.
- This review serves as a guide for clinicians utilizing 18F-FDG PET/CT in oncologic settings.
