Structural MRI scans were acquired on a 3-Tesla General Electric MR750
system with an eight-channel head coil. A high-resolution T1 anatomical scan was
acquired in the sagittal plane with the following parameters: FOV = 24
cm, 256 × 192 matrix, TR = 8.1 ms, TE = 3.192 ms, flip
angle = 12°, TI = 550 ms, bandwidth = 31.25 kHz,
and 172 1.2 mm slices. After the images were acquired, they were visually
inspected for quality control purposes to ensure there were no artifacts that
might affect image processing (e.g., motion).

Whole brain fMRI (fMRI) data were obtained by General Electric MR750 system with an 8-channel head coil while participants kept their eyes open in the scanner. PD were tested on dopaminergic medication. The fMRI images were acquired with a T2*-weighted 2D axial echo-planar pulse sequence (echo time [TE]=30 ms; repetition time [TR]=2000 ms; flip angle=90°; matrix=128×128; slice thickness=5 mm).

Subjects were scanned on a 3 Tesla GE MR 750 system. T1-weighted structural scans were acquired using a 3D FSPGR BRAVO pulse sequence (repetition time, 7.58 ms; echo time, 2.936 ms; flip angle, 12°; image matrix, 256 ^× 256; voxel size, 1 × 1 × 1 mm; 206 contiguous axial slices). T1-weighted images were preprocessed using the VBM8 toolbox (http://dbm.neuro.uni-jena.de/vbm) as implemented in SPM8 (Wellcome Department of Cognitive Neurology) in order to estimate the volume of grey matter, white matter, and cerebral spinal fluid for computation of total intracranial volume for the purpose of correcting insular volumes.

MRI scans were conducted on a 3 Tesla General Electric MR 750 system with 50-mT/m gradients and an 8-channel head coil for parallel imaging (General Electric, Waukesha, Wisconsin, USA). T1-weighted structural scans were acquired using a 3D FSPGR BRAVO pulse sequence (TR = 7.58 ms; TE = 2.936 ms; flip angle = 12°; image matrix = 256 × 256; voxel size = 1 × 1 × 1 mm³; 206 contiguous axial slices). T2*-weighted functional scans were acquired using a SENSE spiral-in pulse sequence along the axial plane (TR = 2000 ms; TE = 30 ms; flip angle = 70°; image matrix = 64 × 128; voxel size = 3.8 × 3.8 × 3.8 mm³; 34 contiguous axial slices).
Preprocessing and statistical analysis of MRI data were performed using the Statistical Parametric Mapping 8 software (SPM8; Wellcome Trust Center for Neuroimaging). Functional images were spatially realigned to correct for head motion artifacts, coregistered to T1-weighted structural images, normalized to the Montreal Neurologic Institute (MNI) space using high-dimensional warping estimated from T1-weighted structural images implemented in the VBM8 toolbox (http://dbm.neuro.uni-jena.de/vbm), smoothed using a 4-mm full-width half-maximum (FWHM) Gaussian kernel, and temporally filtered using a 128-s high-pass filter. The first five images of each run were excluded to focus analysis on images acquired after the magnet achieved steady-state equilibrium.

Standardization of ASL fMRI Data

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

For the ASL fMRI data, corresponding CBF images were obtained using an automated image postprocessing tool embedded in the GE healthcare MR-750 system. Subsequently, the CBF images will be spatially normalized to the standard MNI space by using the transformation fields derived from tissue segmentation of structural images and resampled to 3 mm isotropic voxels. The resulting images will be transformed to z scores using Fisher’s transformation approach and then will be smoothed with 8 mm FWHM isotropic Gaussian kernel.

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.
