Purpose
The MP2RAGE sequence is typically optimized for either T1‐weighted uniform image (UNI) or gray matter–dominant fluid and white matter suppression (FLAWS) contrast images. Here, the purpose was to optimize an MP2RAGE protocol at 7 Tesla to provide UNI and FLAWS images simultaneously in a clinically applicable acquisition time at <0.7 mm isotropic resolution.

Purpose
This work proposes a novel RF pulse design for parallel transmit (pTx) systems to obtain uniform saturation of semisolid magnetization for magnetization transfer (MT) contrast in the presence of transmit field inhomogeneities. The semisolid magnetization is usually modeled as being purely longitudinal, with the applied field saturating but not rotating its magnetization; thus, standard...
