For the repeated measure consistency assessments, we also used open-source test-retest data for 57 subjects scanned two times at an interval of approximately 6 weeks. All the participants were healthy young adult volunteers aged 19 to 30, recruited from Beijing Normal University. All MRI data were obtained using a SIEMENS Trio Tim 3.0 T scanner and T1-weighted MRI was obtained using a sagittal 3D magnetization prepared rapid gradient echo (MP-RAGE) sequence. The details of the imaging parameters and study design can be found in their descriptive paper [9 (link)].

Imaging was performed on a MAGNETOM Trio Tim 3.0T Scanner (Erlangen, Germany) with a Siemens 12 channel Head Matrix Coil. Four T1-weighted images (sagittal, 224 slices, 0.8mm isotropic resolution, TE=3.74ms, TR=2400ms, TI=1000ms, flip angle=8°) and four high-resolution T2-weighted images (sagittal, 224 slices, 0.8 mm isotropic resolution, TE=479ms, TR=3200ms) were obtained. Thirty contiguous minutes of resting state data were collected in ten separate sessions, each on a different day (total time = 300 minutes). The subject visually fixated on a white crosshair presented against a black background. Functional imaging was performed using a gradient-echo EPI sequence (TR=2.2s, TE=27ms, flip angle=90°, voxel size = 4×4×4 mm, 36 slices). In each session, a gradient echo field map sequence was acquired with the same prescription as the functional images.

High-Resolution Brain Imaging Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Data were acquired using a Siemens Trio TIM 3.0T scanner and a 32-channel head coil. Functional images were collected using multi-band echo planar imaging [parameters: repetition time (TR) = 2,000ms, echo time (TE) = 32ms, flip angle α = 62°, field of view (FOV) = 200mm, matrix = 100 × 104, slice thickness = 2mm, 69 slices aligned with the long axis of the HIP, multi-band factor = 3]. High-resolution images were acquired using a 3D MP-RAGE sequence (TR = 2530ms, TE = 2.77ms, α = 7°, FOV = 256mm, matrix = 2562, slice thickness = 1mm, 176 slices).
fMRI data were preprocessed using the Analysis of Functional Neuroimages (AFNI) software package (http://afni.nimh.nih.gov/afni). The first 4 volumes (8s) of each functional dataset were discarded to allow the signal to reach steady-state magnetization. Motion correction and alignment were completed with a single transformation: functional volumes were aligned to each other and to each individual’s high-resolution anatomical scan in one transformation. Each voxel’s time series was scaled (within runs) to a mean of 100 and a maximum of 200 to allow betas to more closely reflect percent signal change. The data were not spatially smoothed.

High-resolution structural T2-weighted (echo time/repetition time = 376 ms/5.0 s; voxel size = 0.45 × 0.45 × 0.90 mm3) volumes were obtained on a 3.0-T Siemens Trio TIM 3.0-T scanner using a 64-channel coil.

Data were acquired using a German Siemens Trio Tim 3.0T scanner (Erlangen, Germany). Head fixers and earplugs were used for all subjects to reduce head movement and machine noise, respectively. The subjects were required to remain motionless, awake, and eye-closed during image acquisition. All patients underwent routine examination (T1W1 and T2W1) to exclude intracranial lesions. The following parameters were used for functional imaging: repetition time/echo time (TR/TE) = 2000/30 ms, 30 slices, 64 × 64 matrix, 90° flip angle, 24 cm FOV, 4 mm section thickness, 0.4 mm gap, and 250 volume (500 s).

All imaging data were acquired on a Trio 3.0 T Siemens Tim scanner at the Brain Imaging Center at South China Normal University, Guangzhou, China. During MR imaging, the participants were asked to refrain from moving their head or closing their eyes and to remain awake. The scan comprised anatomical imaging (5 min) and resting state imaging (8 min). We only used the anatomical imaging data in the current study. A three-dimensional magnetization-prepared rapid gradient-echo (3D MP-RAGE) sequence was used to obtain high-resolution T1-weighted anatomical images (repetition time (TR)/echo time (TE) = 1900 ms/2.52 ms, flip angle = 9°, matrix = 256 × 256, slice thickness = 1.0 mm, field of view (FOV) = 230 × 230 mm2, and voxel size = 1 × 1 × 1 mm3).

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.
