This work presents SELA, a ²³Na MRI sequence that can simultaneously acquire spin-density-weighted (SDW) and SNR-enhanced fluid-attenuated (FLAIR) images in one scan. The sequence was examined by numerical simulation and phantom experiment in a 7T preclinical scanner. Preliminary results support the design purpose to improve ²³Na MRI efficiency and ²³Na-FLAIR image quality.
