Imaging data were collected at the University of Pittsburgh Magnetic Resonance Research Center (MRRC) using a 3T Siemens Trio machine, and 12-channel Siemens head coil. A standard high-resolution T1-weighted volumetric magnetization prepared rapid gradient echo scans (MPRAGE) sequence was acquired in axial orientation (160 slices, 256×240, 1mm isotropic). For the resting-state scan, T2*-weighted BOLD acquisition was done using a gradient-echo echo planar imaging sequence: TR=2,000 msec, TE=34 msec, matrix=128×128×29, voxel size=2×2×3 mm3, oblique axial acquisition, integrated parallel acquisition techniques=2. Images were acquired over 5 minutes (150 volumes). Subjects were instructed to lie still with their eyes open, look at a fixation cross, think of nothing in particular, and not to fall asleep.
Trio machine
Manufactured by Siemens
The Trio machine is a versatile laboratory equipment designed for a variety of applications. It features a compact and durable construction, enabling reliable performance in various laboratory settings. The core function of the Trio machine is to provide a stable and controlled environment for conducting experiments, analyses, or other laboratory-based activities.

Participants were evaluated behaviorally and underwent MRI scanning longitudinally at six different visits at equal intervals from the beginning to the end of the first school year of reading instruction (mean delay between first and sixth visit 12.0 ± 1.1 months) in addition to a seventh visit one year later for a subsample of children (N=8, mean delay from sixth to seventh visit 14.5 ± 3.3 months) (Dehaene-Lambertz et al. 2018) (link). Diffusion MRI data, which constitute the focus of this study, were obtained at three time points (TPs) at the first, sixth, and last visits (herein referred to as TP1, TP2, and TP3; mean ages and standard deviations (SD) at TP1: 6.2±0.3y, at TP2: 7.2±0.4y, at TP3: 8.4 ± 0.3y, Fig. 1, Supplementary Table 1), while behavioral and fMRI data were obtained at each visit (Dehaene-Lambertz et al. 2018) (link). All MRI data were acquired on a 3T Siemens Trio machine with a 12channel head coil.
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.
