Sodium (23Na) MRI has received increased attention as a potential biomarker for disease states thanks to the advent of high and ultra-high field MRI. One asset from 23Na MRI is the distinction between single and triple quantum signal to provide new insights in tissue characterization. Hence, efficient sequences are needed that enable simultaneous 23Na and 23Na multi-quantum-coherences imaging to fully exploit the signal's potential. Therefore, we propose a new sequence utilizing a double-half-echo 23Na readout. Additionally, we propose to exploit this image further to drive the reconstruction of the low resolution MQC images.
