Delta relaxation enhanced magnetic resonance (dreMR) is a new technology, which allows the specific detection of targeted agents only after they have chemically bound to their target molecule. This method utilizes an electromagnet insert coil in order to alter the main magnetic field as a function of time in an otherwise standard MR scanner. Previously, we have developed dreMR insert coils specifically for small animal imaging. In this study, we present a practical, actively shielded, dreMR coil insert design suitable for imaging of the human head.
