Background:

Tumor hypoxia is a critical factor limiting radiotherapy efficacy.
Non-invasive hypoxia imaging using positron emission tomography (PET) shows promise for patient stratification and therapy modification.

Purpose of the Study:

To provide a comprehensive overview of methodologies for hypoxia PET image acquisition, processing, and analysis.
To discuss physical and technical aspects affecting hypoxia PET image acquisition and interpretation.

Main Methods:

Review of recent studies and clinical trials on hypoxia PET imaging.
Analysis of acquisition protocols, data processing, and interpretation methodologies.
Discussion of physical and technical limitations in hypoxia PET.

Main Results:

Hypoxia PET imaging is a valuable tool for assessing tumor oxygenation.
Variability in acquisition and analysis protocols can lead to ambiguities.
Standardization is crucial for multicenter comparisons and trials.

Conclusions:

Standardized hypoxia PET acquisition and analysis protocols are essential for reliable data interpretation.
Development of dedicated protocols will facilitate multicenter trials and hypoxia-based treatment interventions.
Further research is needed to overcome current limitations in hypoxia PET imaging.
