We evaluated magnetization prepared 2 rapid gradient
echoes (MP2RAGE) imaging for deep gray matter
segmentation compared with conventional MPRAGE imaging
and reproducibility of T1 maps. MP2RAGE has high
reproducibility and better tissue contrast than MPRAGE
in deep gray matter, except lateral thalamus. T1 map
derived from MP2RAGE was considered highly reliable.
MP2RAGE is considered useful for measurement and
analysis of the deep GM.
