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.
