images-NIST.003
This set of multi-contrast population-averaged PD brain atlas contains 5 different image contrasts:  T1w ( FLASH & MPRAGE), T2*w, T1–T2* fusion, phase, and an R2* map. Probabilistic tissue maps of whiter matter, grey matter, and cerebrospinal fluid are provided for the atlas. We also manually segmented eight subcortical structures: caudate nucleus, putamen, globus pallidus internus and externus (GPi & GPe), thalamus, STN, substantia nigra (SN), and the red nucleus (RN). Lastly, a co-registered histology-derived digitized atlas containing 123 anatomical structures is included.

We employed a novel T1–T2* fusion MRI that visualizes both cortical and subcortical structures to drive groupwise registration to create co-registered multi-contrast  unbiased templates from 25 PD patients that later went for the STN deep brain stimulation procedure. The finished atlas is in ICBM152 space. Three different resolutions are provided: 1×1×1 mm, 0.5×0.5×0.5 mm, and sectional 0.3×0.3×0.3 mm.

The included files are as followed:
R2* map: PD25-R2starmap-atlas-{0.3mm, 0.5mm, 1mm}
phase map: PD25-phase-atlas-{0.3mm, 0.5mm, 1mm}
