Two pulse biexponentially weighted sodium imaging has
been proposed to provide the desired contrast with good
image quality in short acquisition times. The purpose of
this work was the evaluation of benefits of
biexponentially weighted sodium imaging compared to a
difference image generated from a conventional
double-echo sequence. It was shown that the
biexponentially weighted sequence is more suitable for
future approaches for quantifying the intracellular
sodium content. Also, biexponentially weighted imaging
leads to higher SNR and less B
0
sensitivity.
