Simultaneous Multi-Scanner fMRI Hyperscanning

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

BOLD fMRI data were simultaneously collected from each participant (Patient scanner: Siemens 3T Skyra; Clinician scanner: Siemens 3T Prisma) using a whole-brain, simultaneous multislice, T2*-weighted gradient echo-planar imaging pulse sequence (repetition time = 1,250 ms, echo time = 33 ms, flip angle = 65˚, voxel size = 2 mm isotropic, number of slices = 75, multiband acceleration factor = 5, 624 volumes split into two consecutive scan runs). We decided to keep a designated “patient scanner” and “clinician scanner” rather than randomizing scanner assignment between dyads. This allowed for protocol consistency within patient and clinician groups and facilitated the setup of our hyperscanning infrastructure. In order to maximize patient comfort during scanning, we used the Siemens 3T Skyra for the fibromyalgia patient group, since it has a slightly wider bore compared to the Siemens 3T Prisma.
A T1-weighted high-resolution structural volume (multiecho MPRAGE) was collected to facilitate anatomical localization and spatial registration of individual BOLD fMRI volumes to standard space (Montreal Neurological Institute, MNI152) (repetition time = 2,530 ms, echo time = 1.69 ms, flip angle = 7˚, voxel size = 1 mm isotropic).

Cervical Spondylosis MRI Imaging

MRI was obtained on a 3T MR scanner (3T Prisma; Siemens Healthcare, Erlangen, Germany) using a standard spine coil array for radiofrequency reception. Routine clinical MRI scans consisted of T1-weighted and T2-weighted sequences in the sagittal plane and T2-weighted images in the axial orientation. All patients had radiographic evidence of stenosis, including spinal canal narrowing related to advanced cervical spondylosis manifested by a combination of facet arthropathy, ligamentum flavum hypertrophy, and varying degrees of ventral disc-osteophyte compression.

Diffusion-weighted MRI, functional MRI, and T1-weighted structural images were acquired at the Brown University MRI Research Facility on a Siemens 3T Prisma MRI scanner (Siemens Corp., Erlangen, Germany) equipped with a 32-channel head coil. For each participant, we collected a high-resolution T1-weighted anatomical image (voxel size=1.0 mm³, TR=1900 ms, TE=2.98 ms, FOV=256 mm²) and a 12-minute, 64 direction, diffusion-weighted echo-planar imaging scan (voxel size=1.8 mm3, slices=76, TR=10200 ms, TE=103.0 ms, b=1000 s/mm², b0=12).

Images were acquired at the University of Pennsylvania using Siemens 3 T Prisma. 3D T1 images were obtained in sagittal using repetition time (TR) = 2400 ms, echo time (TE) = 2.24 ms, inversion time (TI) = 1060 ms, flip angle = 8 °, matrix = 320 × 320, slices per slab = 208, and slice thickness = 0.80 mm. The rsfMRIs were recorded using TR = 720 ms, TE = 37 ms, flip angle = 52 °, field of view (FOV) = 208 × 208 mm², matrix = 104 × 104, number of slices = 72, slice thickness = 2 mm, and bandwidth = 2290 Hz/pixel. ASL images were acquired using 1D-accelerated 4-shot 3D stack-of-spirals acquisition with 90 % background suppression, TR = 4250 ms, TE = 9.8 ms, TI = 150 ms, flip angle = 90 °, FOV = 240 × 240 mm², matrix = 96 × 96, slices per slab = 52, and voxel size = 2.5 × 2.5 × 2.5 mm³. Unbalanced pseudo-continuous labeling with a labeling time of 1.8 s, and post labeling delay of 1.8 s was performed at an optimal location perpendicular to straight segments of the internal carotid and vertebral arteries as determined by time-of-flight angiography. Ten label/control pairs were acquired for signal averaging. Two volumes of M₀ images acquired with TR = 6 s and without background suppression were averaged and used to normalize the control-label difference for CBF quantification.

Functional MRI Acquisition and Analysis

Imaging data were acquired using a 3-T MRI scanner (3T Prisma, Siemens Healthcare, Erlangen, Germany) at the Cardiff University Brain Research Imaging Center (CUBRIC). Blood-oxygenation-level-dependent (BOLD) signals during localizer and neurofeedback runs (see Procedure) were measured with a T2^*-weighted gradient-echo echo planar imaging (EPI) sequence synchronized to the onset of the stimulus presentation. Functional EPI volumes of 24 slices of 2.5-mm thickness, with 0.5-mm interslice spacing was used (in-plane resolution = 3 mm, TR = 1,500 ms, TE = 30 ms, flip angle = 80°). High-resolution structural images were acquired before the first functional scan using a magnetization-prepared rapid gradient-echo sequence (MPRAGE) T1-weighted image with 172 contiguous sagittal slices of 1-mm thickness (voxel size: 1 × 1 × 1 mm, TR = 7.9 s, TE = 3.0 ms, flip angle = 20°, FoV = 256 × 256 × 172 mm). Turbo-BrainVoyager (TBV) software (Brain Innovation B.V., Maastricht, Netherlands, version 3.2) was used for online preprocessing and analysis of BOLD signals including motion correction with respect to the first volume of the functional localizer and spatial smoothing [4 mm full width at half maximum (FWHM)].

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.
