In vivo diffusion magnetic resonance imaging (MRI) is critical to access
detailed information about the brain microstructure and connectivity. In
non-human primates (NHPs), especially macaque monkeys, such acquisitions should
be carried out at a submillimeter resolution to enable accurate tractography,
i.e. the 3D reconstruction of white matter fiber tracts. However, the lack of
standardized methods and openly available datasets suitable for tractography
applications has hindered the full deployment of this technique for in vivo
applications in macaques. Here, we present a new diffusion MRI dataset acquired
in 9 macaque monkeys (Macaca fascicularis) with clinical technology (3T MRI
scanner and commercially available MRI coils) at an isotropic resolution of
0.7 mm, together with T1- and T2-weighted anatomical images at an isotropic
resolution of 0.5 mm. This new dataset, called MADI@700 (Macaque Anatomical and
Diffusion Imaging at 700 μm), was curated for tractography applications and
includes a diffusion MRI template of the macaque brain. We illustrate the
quality of this dataset by the extraction of several representative white matter
fiber tracts.
