Initial experiences of using a whole body 9.4 Tesla scanner for sodium MR imaging (105.9MHz) based on twisted projection imaging (TPI) of phantoms and human brain indicate that improved SNR from 3T is achieved without approaching significant specific absorption rate (SAR) set by FDA guidelines. Adequate homogeneity was achieved shimming on the sodium signal. Spatial resolution of better than 5 mm can be achieved in less than 5 minutes without signal averaging.
