Summary
Tumour hypoxia drives aggressive disease and treatment resistance. This review covers magnetic resonance imaging (MRI) techniques for evaluating tumour hypoxia, aiding in understanding and reversing this condition.
Area of Science:
- Oncology
- Medical Imaging
- Biophysics
Background:
- Tumour hypoxia is linked to aggressive cancer phenotypes.
- Hypoxia often causes resistance to cancer therapies.
- Understanding tumour oxygenation is crucial for effective treatment.
Purpose of the Study:
- To review current magnetic resonance imaging (MRI) techniques for evaluating tumour hypoxia.
- To discuss the principles, applications, and limitations of these MRI methods.
- To explore multiparametric imaging approaches for better understanding hypoxia.
Main Methods:
- Review of existing literature on MRI techniques for tumour hypoxia.
- Discussion of principles behind techniques like diffusion-weighted imaging and contrast-enhanced MRI.
- Exploration of potential combinations with PET imaging.
Main Results:
- MRI offers various techniques to assess tumour hypoxia.
- Each technique has specific strengths and limitations in pre-clinical and clinical settings.
- Multiparametric imaging may enhance the understanding of hypoxia's role.
Conclusions:
- MRI techniques are valuable tools for evaluating tumour hypoxia.
- Combining MRI with other modalities like PET can provide a comprehensive view.
- Improved understanding of hypoxia can lead to better treatment strategies and reversal.
