MR images were acquired on a 3.0 Tesla MR scanner (General Electric, Milwaukee, WI, USA). During scanning, foam paddings and earplugs were used to limit head motion and to reduce scanning noise. All of the participants received a three-dimensional magnetization prepared rapid acquisition gradient echo (3DMPRAGE) sequence (repetition time (TR)/echo time (TE) = 8.06/3.12 ms, flip angle = 13°, 176 sagittal slices, voxel size = 1 mm × 1 mm × 1 mm). The resting-state functional images were acquired using an echo-planar imaging (EPI) sequence that is sensitive to BOLD contrast with the following parameters: 40 slices, TR/TE = 2000/30 ms, thickness/gap = 4.0/0.0 mm, voxel size = 3.75 mm × 3.75 mm × 4.0 mm, FOV = 240 × 240 mm, matrix = 64 × 64, flip angle = 90°. Each functional run lasted for 6 min and contained 180 volumes. During the fMRI scans, all of the participants were instructed to keep their eyes closed, relax their minds, and move as little as possible.

Multimodal MRI Brain Imaging Protocol

T1- and diffusion-weighted images (DWIs) were acquired on a 3.0-Tesla MR scanner (GE Healthcare, Milwaukee, WI, USA) with an eight-channel head coil. The parameters of the 3D T1-weighted fast spoiled gradient-echo sequence were: repetition time of 6.3 ms, echo time of 2.1 ms, flip angle of 12°, slice thickness of 1 mm, field of view of 256 × 256 mm², matrix of 256 × 256, and isotropic voxel size of 1 × 1 × 1 mm³.
An echo-planar imaging (EPI) sequence was utilized for DWIs (repetition time = 17,000 ms, echo time = 108 ms, field of view = 240 mm, matrix size = 144 × 144, slice thickness = 1.7 mm, and voxel size = 1.67 × 1.67 × 1.7 mm³). Eddy current effects were minimized by applying the double-echo option. An eight-channel head coil and an array of spatial sensitivity encoding techniques (GE Healthcare) with two sensitivity encoding speed-up factor were used to reduce the impact of EPI spatial distortions. Seventy axial slices parallel to the anterior–posterior commissure line covering the entire brain in 51 directions with a b-value of 900 s/mm² and eight baseline scans with a b-value of 0 s/mm² were acquired. The DTIs were approximated from DWIs using the least-squares method (approximate scan time: 17 min).

All scans were obtained using a 3.0 tesla MR scanner (GE Healthcare, Milwaukee, WI), using the body coil for transmission and an 8-channel phased array coil for reception. Images that were evaluated included: DWI with 6-directional axial diffusion EPI sequences (TR/TE = 7000–12425/76–89 ms, matrix = 256 × 256 × 120, slice thickness = 1.5 mm, FOV = 24 cm × 24 cm × 18 cm, b = 1000 s/mm², NEX = 4) or DWI with 3-directional axial EPI sequences (TR/TE = 13800/80.2 ms, matrix = 110 × 116, slice thickness = 2.5 mm, FOV = 25 cm × 22.5, b = 1000 s/mm², NEX = 4). Volumetric T1-weighted inversion recovery spoiled gradient echo images (TR/TE = 8.86/2.50 ms, matrix = 256 × 256, slice thickness = 1.5 mm, FOV = 24 × 24 cm, TI = 400 ms, Flip angle = 15°) before and after a 5 ml/s bolus injection of 0.1 mmol/kg body weight Gd-DTPA (Magnevist, gadopentetate dimeglumine).

Newborn Brain Diffusion Tensor Imaging

We scanned 20 newborn infants (average post-menstrual age (PMA) = 42.5 weeks, and standard deviation = 2 weeks at the time of scan) with written, informed consent from their parents, as part of a study on the effects of exposure to drugs of abuse on brain development. The study protocol was approved by the Institutional Review Board of the New York State Psychiatric Institute.
DTI data were acquired on a GE 3.0 Tesla MR scanner (Milwaukee, WI). We used a single-shot spin echo, echo planar imaging sequence for DWI acquisitions, with diffusion gradients applied along 11 non-collinear spatial directions at b=600 s/mm² and three baseline images at b=0 s/mm² for each infant. The thickness of each slice was 2.0 mm without gap, and the in-plane resolution was 0.74 mm. Other imaging parameters of the DWI/DTI sequence were: a minimal echo time at approximately 70 ms; repetition time = 13925 ms; field of view =19 cm × 19 cm and acquisition matrix =132×128 (machine-interpolated to 256×256 for post processing). Scan time for each excitation was 3 minutes 43 seconds and the number of excitations was 2. We visually assessed data quality to ensure that each infant had at least one motion-free series. We collected 47 series in total for the 20 infants. Our visual examination identified 27 motion-free and 20 motion-corrupted datasets out of the 47.

MR images were acquired on a 3.0 Tesla MR scanner (General Electric, Milwaukee, WI, USA). During scanning, foam pads and earplugs were used to limit head motion and to reduce scanning noise respectively. All participants received a high resolution T1-weighted brain volume (BRAVO) 3D MRI sequence for obtaining T1 images (repetition time (TR) = 8.1 ms, echo time (TE) = 3.1 ms, 176 sagittal slices, flip angle = 13°, voxel size = 1 mm × 1 mm × 1 mm). After structural imaging, functional imaging during resting-state took place with a single-shot, gradient-echo, echo-planar-imaging (SS-GRE-EPI) sequence sensitive to BOLD contrast. The parameters for resting-state fMRI were as follows: 40 slices, 180 volumes, TR = 2000 ms, TE = 30 ms, no gap, voxel size = 3.75 mm × 3.75 mm × 4.0 mm, FOV = 240 × 240 mm, matrix = 64 × 64, flip angle = 90°. During resting-state fMRI, all the subjects were instructed to lie still with their eyes closed, to move as little as possible, to think about nothing in particular, and not to fall asleep.

Structural MRI brain imaging protocol

All participants were imaged with a 3.0 Tesla MR scanner (GE Healthcare, Milwaukee, WI, USA) by standard head coil at Beijing Tiantan Hospital. This was examined by an experienced neuroradiologist who knew nothing about the participants’ diagnosis. Participants were required to avoid head and neck movements as much as possible, stay awake, relax, and keep eyes closed during the MRI scanning, with earplugs and foam padding to reduce scanner noise and head-movement. Only images without obvious quality problems and pathological changes were included in further analyses. T1-weighted volumetric images were obtained by the 3D BRAVO sequence (coronal acquisition, the field of view (FOV) = 256 mm, acquisition matrix = 256, slice number = 192, flip angle = 15°, TR = 850 ms, TE = 320 ms, voxel size = 1 x 1 x 1.5 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.
