Summary
Positron emission tomography (PET) is a functional imaging technique that aids in detecting and characterizing tumors. Its application in oncology significantly influences treatment decisions for a third of patients, with hybrid imaging enhancing diagnostic capabilities.
Area of Science:
- Oncology
- Medical Imaging
- Nuclear Medicine
Background:
- Positron emission tomography (PET) plays an expanding role in oncological therapy management.
- PET offers functional and quantitative insights into tumor biology.
Purpose of the Study:
- To elucidate the role and benefits of PET in oncological surgery.
- To describe the current applications, indications, and limitations of PET in cancer care.
Main Methods:
- Introduction to the fundamental principles of PET imaging.
- Review of the current status, indications, and limitations of PET in oncology.
Main Results:
- PET enables tumor detection and characterization, aiding in pretherapeutic staging, follow-up, and therapy assessment.
- PET influences therapeutic management in approximately one-third of oncology patients.
- Advancements in radiopharmaceuticals and technology are expanding PET's diagnostic potential.
Conclusions:
- Hybrid imaging, combining PET with CT and MRI, significantly enhances diagnostic accuracy.
- PET-CT and PET-MRI improve diagnostic imaging and increase the overall acceptance and utility of PET in oncological management.
