Delta relaxation enhanced magnetic resonance (dreMR) is a field-shifting quantitative molecular imaging method. The dreMR method is expected to produce higher contrast images at low-fields. Our low-field magnet has a small bore and may interact more strongly with the dreMR system causing a quench. No investigation of induced heating within the bore has been carried out for dreMR. Here, we investigate this interaction with our 0.5T superconducting magnet and find that dreMR pulse sequences do not cause significant heating in the magnet. We therefore state that dreMR is safe to carry out in such systems without quenching the magnet.
