DTI Neuroimaging Protocol for Brain Studies

MRI neuroimaging studies were performed at [blinded for review] on a Siemens Trio 3.0 Tesla scanner with an 8-channel head coil. The imaging protocol included collection of DTI data, which were acquired using a diffusion-weighted imaging (DWI) pulse sequence with diffusion-weighting of b=1000 s/mm² applied in twelve diffusion encoding directions and a single b0 image (see (Alexander et al. 2007 (link))). The acquisition was repeated 4 times and averaged prior to DTI analysis. Whole brain coverage was obtained using sixty contiguous axial slices (matrix = 128 × 128, FOV = 256 mm, resolution = 2 × 2 × 2.5 mm³, averages = 4, TR = 7000 ms, TE = 84 ms, pixel bandwidth = 1346 Hz).

Scans were acquired under propofol anesthesia (10 mg/kg/h) using previously described procedures (Hecht et al., 2013 (link)). The DTI scans were 60-direction images at B = 1000 with isotropic 1.8 mm³ voxels and were acquired on a Siemens Trio 3.0 tesla scanner (TR: 5900 ms; TE: 86 ms; 41 slices). Five B0 volumes were acquired with no diffusion weighting. For 37 individuals, T1-weighted images were acquired on the same scanner with isotropic 0.8 mm³ voxels (TR: 2600 ms; TE: 3.06 ms; slice thickness: 0.8 mm). For the remaining 22 chimpanzees, T1-weighted images were collected using a 3D gradient echo sequence (pulse repetition = 2300 ms, echo time = 4.4 ms, number of signals averaged = 3, matrix size = 320 × 320, with 0.6 × 0.6 × 0.6 resolution). Scans will be made available online at the National Chimpanzee Brain Resource, http://www.chimpanzeebrain.org/.

We employed a Siemens Trio 3.0 Tesla scanner (Erlangen, Germany) at the Department of Radiology, Shanxi Provincial Hospital, China. All EOS patients and TDC completed a T1-weighted structural MRI scan with a magnetization-prepared rapidly acquired gradient echo sequence (repetition time (TR)=1900 ms; echo time (TE)=2.95 ms; inversion time (TI)=900 ms; flip angle (FA)=9° field of view (FOV)=225 × 240 mm²; matrix=240 × 256; slice thickness=1.2 mm, 160 sagittal slices, no gap) and an 8.8-min rfMRI scan using an echo-planar imaging sequence (TR=2500 ms; TE=30 ms; FA=90° FOV=240 mm; matrix=64 × 64; slice thickness=4 mm, 32 axial slices, no gap, 212 volumes). All AOS patients and HAC underwent T1-weighted structural imaging acquired using a three-dimensional fast low-angle shot sequence (TR=14 ms; TE=4.92 ms; FA=25° FOV=230 mm; matrix=256 × 256; slice thickness=1.5 mm, 120 sagittal slices, gap=0.1 mm) and an 8.3- min rfMRI scan obtained using an echo-planar imaging sequence (TR=2000 ms; TE=30 ms; FA=90° FOV=192 mm; matrix=64x64; slice thickness=5 mm, 33 axial slices, no gap and 248 volumes). All the participants received the same instruction. For the rfMRI scans, participants were instructed to close their eyes and remain awake while lying quietly.

3T Resting-State fMRI Acquisition Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

The same Siemens TRIO 3.0 Tesla scanner (Erlangen, Germany) was used
to acquire all images, which were obtained within a single scanning session.
A high-resolution T1-weighted sagittal MPRAGE structural image (TE =
3.08 ms, TR (partition) =2.4 sec, TI = 1000 ms, flip angle
= 8 degrees, 176 slices with 1×1×1 mm voxels) was
obtained and used to compute the atlas transformation.
A BOLD contrast sensitive asymmetric spin-echo echo-planar sequence
(volume TR=2.5 s, in-plane resolution 4×4 mm, T2*
evolution time=27 ms, α=90°) was used for
functional imaging. Thirty-two contiguous, 4 mm-thick axial slices parallel
to the anterior commissure-posterior commissure plane were collected for
whole brain coverage. For rs-fcMRI scanning data acquisition, participants
maintained their gaze on a white fixation cross on a black background.
Subjects had either three or four 3-minute runs or two to four 5-minute
runs. At least 9 minutes of resting state data were collected for each
participant.

Images were acquired on a Siemens Trio 3.0 Tesla scanner with a 12-channel head coil (Siemens Medical, Erlangen, Germany). Participants were shown 20 relaxation images for 30s each during initial scanner tuning, localizing, and structural scanning. A high-resolution T1-weighted MPRAGE anatomical scan (TR = 8.1ms, TE = 3.7ms, flip angle = 8°, field of view = 256mm, 1.0mm) of the entire brain and positioned using a sagittal scout image was acquired for co-registration and normalization of functional images. T2*-weighted gradient echo EPI images were acquired with the following parameters: TR = 2500ms, TE = 27ms, flip angle = 77°, 40 axial slices (FOV = 224 × 224mm, thickness = 3.5mm voxels with 0.5mm gap, in interleaved order, 160 volumes). The scanning planes were oriented parallel to the anterior commissure– posterior commissure line.

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.
