In vivo submillimeter diffusion MRI dataset of 9 macaque brains curated for tractography.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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.
