^*Three-slice averages in multiple planes were used to obtain 0.39×0.39 in-plane resolution and 1.2mm sections.

FSE-Cube = fast spin-echo Cube,

MENSA = multi-echo in the steady-state acquisition,

IDEAL-GRASS = iterative decomposition of water and fat with echo asymmetry and least-squares estimation combined with unspoiled gradient recalled-echo acquired in the steady-state,

IDEAL-SPGR = iterative decomposition of water and fat with echo asymmetry and least-squares estimation combined with spoiled gradient-echo,

COSMIC = coherent oscillatory state acquisition for the manipulation of image contrast,

VIPR-bSSFP = vastly undersampled isotropic projection reconstruction balanced steady-state free precession,

TR: repetition time,

TE: echo time.
