Research summary

Hypoxia is a common condition in solid tumors that is known to reduce the efficacy of radiotherapy and chemotherapy. It would be particularly useful to monitor tumor hypoxia during patient treatments, but there is currently no widely accepted clinical method to measure and monitor hypoxia in vivo in a non-invasive way. In this work, our hypothesis is that hypoxia can be evaluated reliably using magnetic resonance imaging (MRI). MRI R1 relaxation mapping is a promising candidate for this because R1 is sensitive to the presence of dissolved oxygen. It has been reported that the sensitivity to oxygen can be increased by specifically measuring the R1 of tissue lipids instead of the global R1. The increased sensitivity is due to the higher solubility of oxygen in lipids than in water. Existing techniques to map lipids R1 with MRI for tumor hypoxia are limited to single-slice imaging and require long scan times. The goal of this project is to overcome these limitations with a volumetric technique to spatially map lipids R1 in the context of MR-oximetry at 3 T in a clinically acceptable scan time.
