Eight channel coil

Manufactured by Siemens

Sourced in Germany

The Eight-channel coil is a laboratory equipment designed for MRI imaging. It features eight independent receiver channels that enable simultaneous data acquisition from multiple regions of interest. The coil is engineered to provide high-quality signal reception and reliable performance in MRI applications.

Microphone input and headphone output was digitally sampled at 48 kHz and recorded at 16 kHz.
Scanning was performed using a Siemens (Erlangen, Germany) Trio 3 Tesla magnetic resonance scanner with a commercial eight-channel coil. High-resolution T1-weighted anatomical scans (TR = 1.9 s; TE = 3.04 ms; flip angle = 9°; 192 slices per slab; 1 mm³ isotropic voxel size) were obtained to improve spatial normalization of functional images onto the Montreal Neurological Institute (MNI) brain template. Functional images were obtained with a gradient-echo T2*-weighted transverse echoplanar image (EPI) sequence (Task-fMRI (122 volumes; TR = 2 s; TE = 30 ms; silent gap = 6 s; flip angle = 90°; 32 axial slices; 3 mm³ isotropic voxel size), Resting-State (178 volumes; TR = 2 s; TE = 30 ms; flip angle = 90°; 30 axial slices; 3 mm³ isotropic voxel size)).

All participants underwent a structural T1-weighted MPRAGE MRI acquired from a SIEMENS 3.0 T Trio scanner with an eight-channel coil using the following parameters: TR = 1620 ms; TE = 3 ms; 160 1.0 mm slices; flip angle = 15°; matrix = 192 × 256; in-plane resolution = 0.9766 mm × 0.9766 mm. In each session, all pGRN+ and yCTL participants also underwent a 30-directional DWI sequence, acquired using a single-shot, spin-echo, diffusion-weighted echo-planar imaging sequence with GRAPPA acceleration factor of 3. A subset of GRN+ patients were unable or unwilling to participate in the DWI portion of the protocol (N = 6). The diffusion sampling scheme consisted of either one or five images with b = 0 s/mm², followed by measurements with 30 non-collinear/non-coplanar directions isotropically distributed in angular space (b = 1000 s/mm²), TR = 6700 ms, TE = 85 ms, slice thickness = 2.2 mm, and FOV 245 × 245 mm, reconstructed to 2.19 × 2.19 mm in-plane resolution.

Functional MRI Acquisition Protocol

Data acquisition was performed with 1.5 T Avanto (Siemens, Erlangen, Germany) MRI scanner of the Radiology Department of the University of Padova equipped with a standard Siemens eight-channel coil. T2*-weighted EPI were acquired tilting the FOV to avoid signal drop (Weiskopf, Hutton, Josephs, & Deichmann, 2006 ; repetition time [TR] = 2190 msec, echo time [TE] = 49 msec, FOV = 224 mm, flip angle = 90°, 27 axial slices of 64 × 56 voxels, 4.5 mm thick without slice gap, interleaved). Before the beginning of the experimental blocks of trials (256 volumes on each block), localizer sequences were executed to prescribe the position of the slices. The MR scanner was allowed to reach a steady state by discarding the first four volumes in each scan series to ensure that subsequent scans were collected at equilibrium magnetization. A highresolution anatomical scan, 3-D T1-weighted MPRAGE (TR = 1900 msec, TE = 2.91 msec, isotropic voxel size of 1 mm 3 ) was carried out on each participant following the acquisition of the five blocks of trials. Field map was acquired to correct for geometric distortions (TR = 500 msec, TE/ΔTE = 4.76/4.76 msec).

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.
