Whole‐brain quantitative CEST MRI at 7T using parallel transmission methods and correction

Purpose To enable whole‐brain quantitative CEST MRI at ultra‐high magnetic field strengths (B 0 ≥ 7T) within short acquisition times. Methods Multiple interleaved mode saturation (MIMOSA) was combined with fast online‐customized (FOCUS) parallel transmission (pTx) excitation pulses and correction to achieve homogenous whole‐brain coverage. Examinations of 13 volunteers were performed on a 7T MRI system with 3 different types of pulse sequences:...
