Main Methods:

• Review of practical cases illustrating segmentation difficulties in F-FDG PET/CT.
• Analysis of clinical conditions affecting tumor delineation.
• Discussion of potential strategies to overcome segmentation limitations.

Main Results:

• Identified key factors impacting accurate tumor segmentation in NSCLC.
• Presented practical scenarios and corresponding solutions for common segmentation issues.
• Emphasized the importance of standardized segmentation protocols.

Conclusions:

• Addressing segmentation challenges in F-FDG PET/CT is critical for accurate NSCLC assessment.
• Standardized and adaptable segmentation methods are needed for reliable clinical outcomes.
