Current Approaches to Radiation Oncology Target Volume Delineation Using PET/Computed Tomography

Area of Science:

• Oncology
• Medical Imaging
• Radiation Therapy

Background:

• Positron emission tomography (PET) is a key imaging tool in oncology.
• PET aids in cancer diagnosis, staging, outcome prediction, and surveillance.
• Integrating PET with computed tomography (CT) improves radiation therapy planning.

Purpose of the Study:

• To review the role of PET in target volume delineation for radiation oncology.
• To examine clinical data and approaches for thoracic, genitourinary, and head and neck cancers.
• To highlight practical applications of PET in radiation therapy planning.

Main Methods:

• Review of existing data and clinical approaches.
• Focus on three major cancer types: thoracic, genitourinary, and head and neck.
• Analysis of PET's utility in target volume delineation.

Main Results:

• PET significantly enhances target volume delineation in radiation oncology.
• Specific data and current approaches are detailed for thoracic, genitourinary, and head and neck malignancies.
• PET offers practical benefits for radiation therapy planning, supported by recent clinical trials.

Conclusions:

• PET is a valuable modality for improving radiation therapy planning through precise target delineation.
• The integration of PET in treatment planning is supported by clinical evidence across various cancer types.
• PET's application in radiation therapy planning is expanding and has demonstrated clinical utility.
