Resting-state functional connectivity magnetic resonance imaging (MRI) data were collected on a Siemens 3T Trio whole-body scanner using a 16-channel phased-array head coil. For each subject, a scout localizing scan was first acquired for graphic prescription followed by a T2-weighted echo planar imaging volume (TR = 5000 ms, TE = 34 ms, 128 × 128 matrix size, 19.2 cm FoV, thirty-six 4mm axial slices, in plane voxel dimension = 1.50 × 1.50 mm), which was acquired co-planar to the functional volumes to ensure identical distortion characteristics. For the resting-state functional connectivity MRI data, a 6-min T2*-weighted functional scan was acquired while the subjects were asked to fixate on a black crosshair presented on a white screen (TR = 3000 ms, TE = 28 ms, 64 × 64 matrix size, 19.2 cm FoV, thirty-four 4 mm slices, in plane voxel dimension = 3.0 × 3.0 mm). To ensure that subjects were at ease during the scanning session, all participants participated in a mock scan before the date of their MRI.
16 channel phased array head coil

Sourced in Germany
The 16-channel phased-array head coil is a specialized imaging device used in magnetic resonance imaging (MRI) systems. It is designed to provide high-quality imaging of the human head and brain. The coil features 16 individual receiver channels that work together to enhance signal-to-noise ratio and improve overall image quality. This equipment is an integral component of MRI scanners, enabling detailed visualization and analysis of the brain and associated structures.

MRI data of all PD patients were collected during the ON medication state. Functional and structural data were acquired with a 3-Tesla system (Siemens, Erlangen, Germany) and a 16-channel phased-array head coil. Resting-state functional BOLD images were obtained by using a single-shot echo-planar imaging (EPI) sequence (33 axial slices, repetition time (TR) = 2,000 ms, echo time (TE) = 21 ms, field of view = 224 mm × 224 mm, flip angle (FA) = 78°, voxel size = 3.5 × 3 0.5 × 4.0 mm3, matrix = 64 × 64, slice thickness = 4.0 mm, 220 time points) . Anatomical images were acquired by using a 3D T1-weighted MPRAGE sequence in the sagittal orientation (TR = 1,900 ms, TE = 2.19 ms, FA = 9°, FOV = 250 mm × 250 mm, slice thickness = 1.0 mm, no gap). Axial FLAIR, T2W, T1W, and sagittal T2W were acquired to exclude subjects who had space-occupying lesions and cerebrovascular diseases.

The fMRI measurements were obtained on a 3-Tesla Siemens Verio scanner (Siemens, Erlangen, Germany) with a 16-channel phased-array head coil. The baseline MRI scan was performed 2 h before the TBS implementation, and the post-TBS scan was completed within 30 min after TBS. The rs-fMRI parameters were as follows: repetition time (TR) = 2,000 ms, echo time (TE) = 21 ms, flip angle (FA) = 90°, field of view (FOV) = 240 mm × 240 mm, matrix = 64 × 64, slice thickness = 4.0 mm, 33 axial slices, and voxel size = 3.75 mm ×3 0.75 mm × 4.0 mm.
Structural images were acquired using a magnetization-prepared rapid gradient echo (MPRAGE) sequence with the following parameters: TR = 2,530 ms, TE = 2.93 ms, FA = 7°, FOV = 256 mm × 256 mm, and a slice thickness of 1.0 mm with no gap.
During the period of rs-fMRI scanning, participants were asked to relax with their eyes closed but not to fall asleep and asked to empty their minds of anything in particular. After MR scanning, they completed a simple questionnaire to confirm their wakefulness during the scanning.

The MRI data were acquired using the same Siemens Trio 3 T scanner with a 16-channel phased array head coil at the Beijing University center and the Beijing Huilongguan Hospital center. MRI scanning included the collection of 3D T1-weighted structural MRI with a 1 mm3 isotropic voxel size (TR = 2530 ms, TE = 2.98 ms, TI = 1100 ms, flip angle = 7°, FOV = 256 × 224 mm2, and 192 sagittal slices) and diffusion-weighted MRI (DWI) with a 2 mm3 isotropic voxel size (64 diffusion directions with b = 1000 s/mm2 and 10 images with b = 0 s/mm2, TR = 7500 ms, TE = 64 ms, flip angle = 90°, FOV = 224×224 mm2, and 70 axial slices). The preprocessing procedures for dMRI data comprised the correction of the eddy current and motion artefacts, the estimation of the diffusion tensor elements, and the calculation of the fractional anisotropy (FA). The eddy current distortions and motion artefacts in the dMRI data were corrected by applying an affine alignment of each DWI image to the b0 image. Then the diffusion tensor elements were estimated by solving the Stejskal and Tanner equations, and the FA value of each voxel was calculated. All procedures were executed using the FMRIB’s Diffusion Toolbox of the FMRIB Software Library (https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FDT ).

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.
