Comparison of Biexponentially Weighted and Double-Echo Sodium Imaging

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.
