Advances in neuro-oncology imaging.

Area of Science:

• Neuro-oncology
• Nuclear Medicine
• Radiology

Background:

• Conventional MRI has limitations in defining brain tumor extent and distinguishing tumor from treatment effects.
• Amino acid PET imaging has emerged as a valuable tool to address these MRI shortcomings.
• International guidelines recommend amino acid PET for brain tumor management.

Purpose of the Study:

• To review the clinical utility of amino acid PET in brain tumor diagnosis and management.
• To compare amino acid PET with advanced MRI techniques for specific clinical applications.
• To provide an outlook on future advancements in PET and MRI for neuro-oncology.

Main Methods:

• Review of clinical applications of amino acid PET in brain tumors.
• Comparison of amino acid PET with advanced MRI techniques (e.g., MRS, PWI).
• Summary of current evidence and future trends.

Main Results:

• Amino acid PET improves differential diagnosis of brain tumors.
• It aids in delineating tumor extent for treatment planning and biopsy guidance.
• It is crucial for differentiating tumor recurrence from treatment-related changes and monitoring therapy response.

Conclusions:

• Amino acid PET is a valuable adjunct to MRI for comprehensive brain tumor management.
• Integration of advanced PET and MRI techniques offers improved diagnostic accuracy.
• Future developments promise further enhancements in neuro-oncological imaging.
