Deuterium metabolic imaging (DMI) is a powerful new method to supplement the anatomical and functional information of MRI with a metabolic component. A reduction in overall scan time by interleaving MRI and DMI is clinically relevant, whereas research applications can benefit from complimentary information obtained through interleaved acquisition. Because most MR scanners only allow acquisition of one frequency, additional hardware is required to enable interleaved acquisition. Here we present hardware for the upconversion of 2H data into the 1H receive path and present a solution to achieve effective phase and frequency locking.
