Imaging was performed using a Siemens Verio 3.0 Tesla scanner (Siemens, Erlangen, Germany) with a homogeneous birdcage head coil at the Affiliated Second Hospital of An Hui Medical University. High resolution spoiled gradient-recalled echo (SPGR) 3D axial images were acquired for anatomical reference. The SPGR parameters were: repetition time (TR) = 1900 ms, echo time (TE) = 2.48 ms, flip angle (FA) = 9°, acquisition matrix = 256 × 256, field of view (FOV) = 240 × 240 mm, thickness = 1.0 mm, gap = 0 mm, number of slices = 176, number of excitations (NEX) = 1.0. Axial resting-state functional connectivity fMRI (R-fMRI) datasets were obtained in 8 min with a gradient-recalled echo-planar imaging (GRE-EPI) pulse sequence. The R-fMRI imaging parameters were: TR = 2000 ms, TE = 25 ms, FA = 90°, acquisition matrix = 64 × 64, FOV = 240 × 240 mm, thickness = 4.0 mm, gap = 0 mm, NEX = 1.0, number of slices = 36. During the data scans, all subjects were instructed to relax and keep their eyes closed, and a pair of stabilizers was used to immobilize their heads.
Verio 3.0 tesla scanner
Manufactured by Siemens
Sourced in Germany
The Verio 3.0 Tesla scanner is a magnetic resonance imaging (MRI) device manufactured by Siemens. It is designed to produce high-quality images of the body's internal structures using a strong magnetic field and radio waves. The Verio 3.0 Tesla scanner is capable of capturing detailed images of the human body, which can be used for medical diagnosis and research purposes.

In this study, fMRI data were acquired using a Siemens Verio 3.0 Tesla scanner (Siemens, Erlangen, Germany) with a standard 12-channel head coil. A gradient echo planar imaging sequence was used with the following parameters: 34 axial slices, repetition time (TR) = 2700 ms, echo time (TE) = 30 ms, flip angle = 90°, field of view (FoV) = 220 × 220 mm, matrix = 64 × 64, and thickness = 3.4 mm. The acquired voxel dimension was 3.4 × 3.4 × 3.4 mm.
EEG data were acquired with an MR-compatible EEG amplifier (BrainAMP MR, Brain Products, Munich, Germany) at a sampling rate of 5,000 Hz, using 64 electrodes in the extended 10–20 montage, plus one extra electrocardiogram electrode. The 64 electrodes included two electrodes monitoring eye movement, thus the remaining 62 electrodes were used for further analysis. An experienced specialist (L.G.) positioned the EEG caps on the subjects. To ensure valid standard positions, the electrode Cz was placed halfway between the nasion and the inion, and was right-left-centered. The reference was set at the mid-frontal position FCz, and the impedances were kept below 10 kΩ. The data were transmitted via fiber optics outside the scanner room. To facilitate the removal of MR-induced artifacts from the EEG data, the sampling clocks of the EEG and MRI systems were synchronized by the Sync box (Brain Products, Munich, Germany).

Imaging was performed using a Siemens Verio 3.0 Tesla scanner (Siemens, Erlangen, Germany) with a homogeneous birdcage head coil at the Affiliated ZhongDa Hospital of Southeast University, including high-resolution spoiled gradient-recalled echo (SPGR) 3D axial images and R-fMRI scans. During the data scans, all subjects were instructed to relax with their eyes closed, and stabilizers were used to immobilize the heads of the subjects.

MRI was performed on a Siemens Verio 3.0 Tesla scanner using a 32-channel head coil. Each patient had standard high-resolution structural imaging, acquired with the following parameters: T1 MPRAGE (TE = 2.98 s, TR = 2.3 s, 1 mm isotropic voxel, 256 × 256 mm field of view, FA = 9, GRAPPA = 2, 5 min scanning time), T2 FLAIR (TE = 395 ms, TR = 5 s, 1 mm isotropic voxel, 250 × 250 mm field of view, GRAPPA = 2, 6 min scanning time). For diffusion-MRI, the NODDI multi-shell protocol included one shell with 30 gradient directions and b = 700 s/mm2 and another with 60 directions and b = 2000 s/mm2. The protocol also contained nine images without diffusion weighting (b = 0 s/mm2) and a single reversed-phase encoding image without diffusion weighting. The EPI multiband readout (multiband factor = 3, TE = 105.2 ms, TR = 5 s) used a matrix size of 128 × 128 over a field of view of 256 × 256 mm2 and slice thickness of 2 mm, resulting in isotropic voxels of 2 mm3. A total of 66 contiguous slices were acquired for whole-brain coverage. The total scanning time for the NODDI protocol was 10 min. An additional single-shell acquisition (64 directions, b = 1000 s/mm2) was acquired for comparison.

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.
