Multi‐echo Length and Offset VARied Saturation (MeLOVARS) method for improved CEST imaging

Purpose The aim of this study was to develop a technique for rapid collection of chemical exchange saturation transfer images with the saturation varied to modulate signal loss transfer and enhance contrast. Methods Multi‐echo Length and Offset VARied Saturation (MeLOVARS) divides the saturation pulse of length T sat into N = 3–8 submodules, each consisting of a saturation pulse with length of T sat /N (∼0.3–1 s), one or more low flip‐angle...
