MR imaging was performed at the ISMMS using either a 3T Siemens Allegra scanner or a 3T Siemens Skyra scanner with a 12-channel dedicated head coil. All individuals were instructed to lie still, and motion was minimized by using foam pads to secure individuals’ heads. During the resting state fMRI scan all individuals were instructed to “rest, but stay awake with your eyes closed.” We acquired a 6-minute blood oxygen level dependent (BOLD) scan using a T2*-weighted echo planar sequence in 39 individuals (16 HC, 12 individuals with SPD and 11 individuals with schizophrenia) on the Siemens 3T Allegra (matrix=64×64, slices=32, 3.28 × 3.28 × 3.0 mm3 voxel size, TR=2s, flip angle=90 degrees and 180 volumes). In addition, a 3D T1-weighted MP-RAGE provided 208 slices in a 256×256 matrix (TR=2500 ms, TE=4.4 ms, FOV=21 cm, slice thickness = 0.82 mm). In 69 individuals (27 HC, 33 participants with SPD and 9 individuals with schizophrenia) we acquired a 10-minute blood oxygen level dependent (BOLD) scan on the Siemens Skyra scanner using a T2*-weighted echo planar sequence (matrix = 98×98, slices=60, 2.33 × 2.33 × 2.33 mm3 voxel size, TR = 2s, flip angle = 60 degrees, and 300 volumes). In addition, a 3D T1-weighted MP-RAGE provided 244 slices in a 320×320 matrix (TR=2400 ms, TE=2.07, FOV=25.6 cm, slice thickness=.80 mm).

This study evaluates variability in diffusion-weighted measurements across sites available in the PRIME-DE project, as well as between human MRI scanner models and vendors used to acquire the images. From the 25 sites in the database, 8 gathered diffusion data, and only 4 have a fair number of subjects (N ≥ 4): Aix-Marseille University (Aix-Marseille, 4 subjects, Siemens Prisma scanner), University of California, Davis (UC-Davis, 19 subjects, Siemens Skyra scanner), Mount Sinai School of Medicine—Philips (Sinai-Philips, 9 subjects, Philips Achieva scanner), and Siemens (Sinai-Siemens, 6 subjects, Siemens Skyra scanner). All subjects are Macaca Mulatta primates, anesthetized before acquisition. The scan sequence parameters can be found in Table 1 . All datasets were acquired using 3T systems, with DWI at spatial resolutions from 0.7 to 1.4 mm3–isotropic or rectangular voxels—and anatomical images from 0.3 to 0.8 mm3 isotropic voxels.

Participants lay in the scanner with a response button box placed in their right hand. Visual stimuli were projected onto a screen, viewed via a mirror attached to the inside of the head coil, to keep participants focused on the task so that they would respond in time. Participants wore earphones to hear the auditory stimuli and two ear pads were used to attenuate the scanner noise. The two phonological task runs were counterbalanced across participants.
Images were acquired using 3.0T Skyra Siemens scanner with a 64-channel headcoil. The blood oxygen level dependent (BOLD) signal was measured using a susceptibility weighted single-shot echo planar imaging (EPI) method. Functional images were acquired with multiband EPI (TE = 30 ms, flip angle = 80, matrix size = 128 × 128, FOV = 256 mm, slice thickness = 2 mm without gap, number of slices = 56, TR = 1250 ms, Multi-band accel.factor = 4, voxel size = 2 × 2 × 2). A high resolution, T1 weighted 3D image was acquired. The following scan parameters were used: TR = 1900 ms, TE = 2.34 ms, matrix size = 256 × 256, field of view = 256 mm, slice thickness = 1 mm, number of slices = 192.

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.
