MRI imaging was conducted in a 3T scanner (Siemens Prisma) with a 32-channel gradient head coil at the Athinoula A. Martinos Center for Biomedical Imaging in Charlestown, MA, United States. All subjects were scanned in the same scanner at both time points, i.e., within 2 weeks before (pre-scan) and within 2 weeks (post-scan) after participating in the 8-week program (∼3-month interval). We acquired T1 structural MRI images (sagittal MP-RAGE) for all subjects using the following parameters: TA = 9:14; voxel size = 1.1 mm × 1.1 mm × 1.2 mm; Rel.SNR = 1.00; slice oversampling = 0%; slices per slab = 176; TR = 2300 ms; TE = 2.01 ms; field of view = 270 mm. Subsequently, resting state functional magnetic resonance imaging (rsfMRI) were acquired using a gradient-echo echo-planar pulse sequence sensitive to the blood-oxygen-level-dependent signal (BOLD) with the following parameters: TR = 3000 ms; voxel size = 3.0 mm isotropic voxels; Rel.SNR = 1.00; interleaved slice order, slice oversampling = 0%; slice thickness = 3 mm; TE = 30 ms; Flip Angle = 85°; TA = 6:12; 46 slices, field of view = 216 mm.
32 channel gradient head coil

Sourced in United States, Jersey
The 32-channel gradient head coil is a specialized piece of lab equipment designed for use in magnetic resonance imaging (MRI) systems. It is responsible for generating the magnetic field gradients required for spatial encoding during the imaging process. The 32 independent channels allow for enhanced spatial resolution and image quality compared to standard gradient coil designs.

We used a Siemens Magnetom Trio Tim 3 T fMRI scanner with a 32-channel gradient head coil. We conducted a localizer scan, followed by a whole brain magnetization prepared rapid gradient echo (MPRAGE) sequence to acquire high-resolution T1-weighted images (TR/TE/flip angle = 2.17 s/4.33 ms/7°, field of view (FOV) = 256 × 256 mm2, matrix = 256 × 256, slice thickness = 1.2 mm, voxel size = 1 × 1 × 1.2 mm3).
Functional MRI images were acquired using a blood oxygen level dependent (BOLD) echoplanar (EPI) T2*-weighted sequence (TR/TE/flip angle = 2.0 s/30 ms/90°, FOV = 220 × 220 mm2, matrix = 64 × 64, slice thickness = 4 mm, voxel size = 3.44 × 3.44 × 4 mm3). The T1- and T2*-weighted images were collected in the same plane (30 axial slices angled perpendicular to the AC/PC line) with an interleaved excitation order and foot to head phase encoding.
We acquired whole brain diffusion-weighted images using a spin-echo echo-planar sequence along 30 diffusion gradient directions and with a b value of 1000s/mm2 (TR/TE/flip angle = 9.5 s/91 ms/90°, b value = 1000s/mm2, FOV = 240 × 240 mm2, matrix = 96 × 96, slice thickness = 2.5 mm, voxel size = 2.5 × 2.5 × 2.5 mm3). Two normalization images with no diffusion encoding (b value = 0) were acquired in the beginning of the sequence.

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.
