Delta relaxation enhanced magnetic resonance (dreMR) is an emerging method for performing molecular imaging, which utilizes a removable electromagnetic coil to modify the strength of the main magnetic field during an MRI pulse sequence. The purpose of this field-cycling method is to acquire information about the binding state of targeted contrast agents that is not obtainable with static-field MRI methods. This work describes a method for advancing dreMR from qualitative imaging to quantitative measurement of contrast agent binding. By measuring the concentration of bound agent, the corresponding concentration of the target molecule can determined.
