MRI data were collected from all subjects (except the young adults) using a MAGNETOM Trio 3.0 T MR scanner (Siemens, Germany), including T1 anatomical (176 sagittal slices, 1‐mm in‐plane resolution) and T2‐weighted fluid attenuated inversion recovery (FLAIR; voxel size 0.5 × 0.5 × 1 mm, 160 slices) images covering the whole brain. Young adults were scanned using a dedicated 3.0 T Siemens PRISMA scanner (Siemens, Germany), with a 64‐channel head coil and similar parameters. Detailed descriptions of the MRI scan protocols have been reported in previous studies (Gao et al., 2019 (link); Gao et al., 2021 (link); Wang et al., 2017 ; Xiao et al., 2018 (link)).
Magnetom trio 3.0 t mr scanner
Manufactured by Siemens
Sourced in Germany
The MAGNETOM Trio 3.0 T MR scanner is a magnetic resonance imaging (MRI) system designed by Siemens. It operates at a magnetic field strength of 3.0 Tesla, which enables high-resolution imaging and enhanced signal-to-noise ratio. The core function of the MAGNETOM Trio is to acquire and produce detailed images of the body's internal structures and organs for medical diagnostic and research purposes.

All resting-state fMRI and T1-weighted images were obtained on a MAGNETOM Trio 3.0 T MR scanner (Siemens, Germany). Participants were instructed to rest with closed eyes and stay awake. Resting-state images were acquired by a gradient echo planar imaging (EPI) sequence: TR/TE = 2,000/30 ms, FOV = 240 × 240 mm, flip angle (FA) = 78°, matrix = 64 × 64, thickness = 4.0 mm, number of slices = 35, and voxel size = 2.4 × 2.4 × 2.4 mm3. High-resolution sagittal T1-weighted images were collected with a three-dimensional magnetization-prepared rapid gradient echo (3D-MPRAGE) sequence: TR/TE = 2,000/2.3 ms, thickness = 1.0 mm, FA = 8°, FOV = 225 ×240 mm and voxel size = 1 × 1 × 1 mm3.

MR imaging was carried out using a Siemens Magnetom Trio 3.0T MR scanner (Erlangen, Germany). Functional images were collected axially by using an echo-planar imaging (EPI) sequence sensitive to BOLD contrast. The acquisition parameters were as follows: 36 slices, 3000/30 ms (TR/TE), 4 mm thickness, 220×220 mm (FOV), 64×64 (resolution within slice), 90° (flip angle). The FOV covered all brain regions for all participants. Resting state was collected during the fMRI and lasted 9 minutes with 180 volumes obtained. During the resting state scan all subjects were instructed to stay as motionless as possible with their eyes closed and to not think of anything in particular. Additionally, for spatial normalization, each participant received a 3D anatomical MRI image with a T1-weighted magnetization-prepared rapid-acquisition gradient echo (MP-RAGE). The protocol was as follows: sagittal, repetition time = 2000 ms, echo time = 2.26 ms, inversion time = 900 ms, flip angle = 8°, slice thickness = 1 mm, FOV = 256 × 256 mm2, in-plane resolution = 1 × 1 mm2.

MRI data were collected using a MAGNETOM Trio 3.0 T MR scanner (Siemens, Germany). The scanning sessions included (1) T1 high-resolution anatomical images (176 sagittal slices, 1-mm in-plane resolution); (2) resting-state BOLD volumes (33 axial slices, 3.8-mm slice thickness with a 0.3-mm gap, repetition time (TR) = 2 s, 240 volumes); (3) diffusion tensor imaging (DTI) (TR/ echo time (TE) = 6000/93 ms, matrix = 128 × 128, 44 axial slices, 2.0 mm slice thickness, b values =0 and 1000s/mm2) in 64 directions; (4) susceptibility-weighted imaging (SWI) (TR/TE = 29/20 ms, voxel size 0.5 × 0.5 × 2 mm, 128 slices, 2 mm thickness); (5) fluid attenuated inversion recovery (FLAIR) sequence (TR/TE/ inversion time (TI) = 6000/396/2200 ms, voxel size 0.5 × 0.5 × 1 mm, 160 slices, 1 mm thickness); and (6) perfusion imaging using Q2TIPS pulsed arterial spin labeling (PASL) sequence (TR /TE = 2500/11 ms, matrix = 64 × 64, flip angle = 90°, slice thickness = 6 mm). During the R-fMRI scan, subjects were asked to remain as till as possible, keep their eyes closed, not fall asleep, and avoid thinking systematically.

Upper abdominal MR examination was performed on each patient using a Magnetom trio 3.0 T MR scanner (Siemens Healthcare Sector, Erlangen, Germany). Before the examination, the patients were fasted for 6 to 8 h and received adequate respiratory training. The main scan sequences and parameters include T1 weighted image (T1WI), T2 weighted image (T2WI), T1 mapping, and diffusion weighted image (DWI). The contrast agent was administrated by an automatic injector at a rate of 2 mL/s (0.025 mmol/kg). The images of gadoxetic acid-enhanced arterial phase, portal venous phase, equilibrium phase and hepatobiliary phase were acquired at 10–40 s, 50–80 s, 90–120 s and 20 min after contrast agent administration, respectively.
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.
