Sodium levels are tightly regulated in the human body. Therefore monitoring total sodium and triple-quantum filtered sodium (as a measure of intracellular sodium) are of great interest for a variety of diseases of the central nervous system. A sequence that enables acquisition of tissue sodium concentration weighted and triple-quantum filtered sodium images in the same run is presented, using two different TPI readouts. Phantom and in vivo results from 9.4T show very good resolution and SNR.
