This dataset was acquired using a Siemens Trio 3T MRI system with a 32‐channel head coil. High‐resolution T1‐weighted structural images were acquired using an MPRAGE sequence (TR = 1900 ms, TE = 2.53 ms, flip angle = 9°, 176 slices, 1‐mm isotropic voxels). The functional MRI data were recorded by a T2*‐weighted EPI pulse sequence (TR = 2000 ms, TE = 20 ms, flip angle = 90°, field of view = 224 × 224 mm, in‐plane resolution = 3.5 × 3.5 mm, 38 slices, slice thickness = 3.5 mm with 1.1 mm gap).

Imaging was conducted at the Donders Institute for Brain, Cognition and Behavior (Nijmegen, the Netherlands). The functional images were collected with a Siemens Trio 3 T MRI system (Siemens, Erlangen, Germany) with an EPI sequence using a 32 channel head coil (TR = 1.74 s, TE = 30 ms, GRAPPA acceleration factor 3, 83° flip angle, 30 slices in ascending order, voxel size 2 × 2 × 2 mm).

Imaging data including T1-weighted structural and resting-state functional scans and T2w-FLAIR images were collected using the Siemens Trio 3T MRI system. High-resolution T1-weighted, sagittal 3D fast-field echo sequences were first obtained, covering the whole brain with the following parameters: 176 slices, echo time = 3.44 ms, repetition time = 1900 ms, slice thickness = 1 mm, inversion time = 900 ms, flip angle = 9°, acquisition matrix = 256 × 256, and the field of view = 256 × 256 mm2. Then, gradient echo EPI sequence was used to obtain rs-fMRI scanning, with TR = 2000 ms, flip angle = 90°, TE = 30 ms, slice thickness = 3.5 mm, 36 axial slices, FOV = 200*200 mm, and acquisition matrix = 64 × 64. Finally, the T2w-FLAIR sequence was collected (repetition time = 9000 ms, slice thickness = 3 mm, echo time = 81 ms, flip angle = 150°, and the number of slices = 25) to measure white matter hyperintensities (WMHs).

Imaging data were collected using a Siemens Trio 3-T MRI system including DTI data and T1-weighted image scans. Participants were positioned supine with their head snugly fixed by straps and foam pads to minimize head movement. Diffusion-weighted imaging was performed using a single-shot, twice-refocused, diffusion-weighted echo planar sequence aligned along the anterior-posterior commissural plane. T1-weighted, sagittal three-dimensional magnetization prepared rapid gradient echo (MP-RAGE) sequences were acquired and covered the entire brain. The parameters of DTI and T1-weighted images refer to our previous study (23 (link)).

Image acquisition was performed using a Siemens Trio 3 T MRI system (Siemens, Erlangen, Germany) with a 32 channel head coil. Diffusion weighted imaging (DWI) data were acquired with the following parameters: repetition time = 7800 ms, echo time = 112 ms, voxel size = 2.5 × 2.5 × 2.5 mm3. Sixty diffusion-weighted images (b = 3000 s/mm2), and seven non-diffusion weighted images (b = 0) were acquired with a spin-echo echo planar imaging sequence. A pair of non-diffusion weighted images with opposite phase encoding was also acquired to correct for susceptibility induced distortion. In addition, T1-weighted MPRAGE images (repetition time = 1900, echo time = 2.63 ms; flip angle = 9°; voxel size = 0.8 × 0.8 × 0.8 mm3) were acquired. Lastly, T2-weighted double inversion recovery SPACE images (repetition time = 7400 ms, effective echo time = 105 ms; inversion times = 3000 and 450 ms, echo train length = 194, flip angle = 120°; voxel size = 1.1 × 1.1 × 1.1 mm3 sagittal acquisition) were obtained for patients to identify T2 hyperintense brain lesions. Lesions were segmented and verified by a neuroradiologist of nine years experience (EL), who was blinded to each patient's clinical status using MRIcro (www.cabi.gatech.edu/mricro/mricro/ ).

Retinotopic mapping data were acquired and analyzed using identical methods to those reported in our previous study (Lawrence et al., 2018 (link)). In brief, brain responses to rotating wedge and expanding ring checkerboard stimuli were acquired using a Siemens 3T Trio MRI system (Siemens, Erlangen, Germany) with a 32-channel head coil and a T2*-weighted gradient-echo EPI sequence (TR 1500 ms, TE 40 ms, 68 slices, 2 mm isotropic voxels, multi-band acceleration factor 4). One high resolution anatomical image was also acquired with a T1-weighted MP-RAGE sequence (TR 2300 ms, TE 3.03 ms, 1 mm isotropic voxels, GRAPPA acceleration factor 2). Anatomical data were automatically segmented into white matter, gray matter and CSF using FreeSurfer (http://surfer.nmr.mgh.harvard.edu/ ). Functional data were analyzed using the phase encoded approach in MrVista (http://white.stanford.edu/software/ ). Polar angle and eccentricity data were visualized on an inflated cortical surface and the boundaries of V1, V2 and V3 were drawn manually using established criteria (Engel et al., 1994 (link); Sereno et al., 1995 (link); Wandell et al., 2007 (link)).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
