Structural brain images were acquired at the Neuroimaging Service of the Pablo de Olavide University (Seville, Spain) using a 3T Philips Ingenia CX MRI scanner equipped with a 32-channel receiver head coil (Philips, Best, The Netherlands). Head motion was minimized by placing foam padding around the subject’s head. One high-resolution three-dimensional (3D) T1-weighted magnetization-prepared rapid gradient echo (MP-RAGE) sequence was acquired in the sagittal plane. Acquisition parameters were empirically optimized to enhance the gray/white matter (WM) contrast with repetition time (TR)/echo time (TE) = 2600/4.7 ms, flip angle (FA) = 9°, voxel resolution = 0.65 mm isotropic, acquisition matrix = 384 mm × 384 mm, resulting in 282 contiguous slices without gap between adjacent slices, acceleration factor (SENSE) = 1.7, and field of view (FOV) = 250 mm × 250 mm × 183 mm.
Ingenia cx mri scanner
Manufactured by Philips
The Ingenia CX MRI scanner is a magnetic resonance imaging (MRI) system developed by Philips. It is designed to capture detailed images of the body's internal structures using strong magnetic fields and radio waves. The core function of the Ingenia CX MRI scanner is to provide high-quality medical imaging for healthcare professionals to aid in diagnosis and treatment planning.

All scanning was performed in a single 3 T Philips Ingenia CX MRI scanner (2015 model). Pre-neurofeedback scanning comprised a 3D T1-weighted sequence of 240 sagittal slices with voxel resolution = 0.75 × 0.75 × 0.75 mm3, repetition time = 9.90 ms, echo time = 4.60 ms, flip angle = 8; and a diffusion-weighted sequence of 66 axial slices with voxel resolution = 2.05 × 2.05 × 2.20 mm3, repetition time = 9000 ms, echo time = 90 ms, flip angle = 90, featuring 72 non-collinear directions (b = 1300 s/mm2) and one non-gradient volume (b = 0 s/mm2). During neurofeedback, echo planar imaging was used with voxel resolution = 3 × 3 × 3 mm3, repetition time = 3000 ms, echo time = 35 ms, matrix size = 80 × 80 voxels, field of view = 240 mm and interleaved slice acquisition with an interslice gap of 0.2 mm (45 slices, whole brain coverage). In total, 610 functional volumes were acquired.

Images were acquired using a 3T Ingenia CX MRI scanner (Philips Healthcare, The Netherlands) equipped with a 32-channel head coil. Initially, the brain was scanned using a 3D dual gradient echo sequence with a FOV of 220 × 180 × 120 mm3 (voxel size 3.4 × 4 × 5 mm3) to acquire a B0 field map, which was then used for image-based field shimming. 3D R1ρ-weighted axial images were obtained using an R1ρ spin-lock preparation (90×-τ/2y-180y-τ/2−y-90×) turbo spin-echo pulse sequence. The acquisition parameters were TR/TE = 3000/10 ms, FOV of 220 × 180 × 120 mm3, voxel size of 1 × 1 × 5 mm3, three locking times; 2, 20, and 48 ms, and two locking field frequency (FSL) of 0 and 300 Hz resulted in 6 dynamics. The scan time for each dynamic was 1 min and 18 sec. The whole brain of each participant was also imaged using conventional multislice T2-FLAIR, 3D-SWI (susceptibility-weighted images), DWI (diffusion-weighted images), and a T1-weighted 3D MPRAGE pulse sequence used for segmentation. All images were reviewed by a board‐certified neuroradiologist (LTD).

MRI scans were acquired from using a 3 Tesla Philips Ingenia CX MRI scanner with a 32-channel dStream head coil. Functional MRI images were acquired using an FFE single-shot GRE-EPI sequence. The acquisition parameters were as follows: TR = 2,000 ms, TE = 30 ms, and flip angle = 90°. Data were collected with an in-plane resolution of 3 × 3 mm and slice thickness 3 mm with matrix dimensions of 80 × 80 voxels and 36 slices.
High-resolution T1-weighted images were collected at each session for co-registration of functional images. The acquisition parameters were as follows: TR = 8.2 ms, TE = 3.7 ms, and flip angle = 8°. Data were collected with an in-plane resolution of 1 × 1 mm and slice thickness of 1 mm with matrix dimensions of 288 × 288 voxels and 213 slices.

Structural and functional images were collected via a 3.0T Philips Ingenia CX MRI Scanner with a SENSE 32‐channel head coil, located at the Department of Radiology of the University Hospital in Leuven, Belgium. Soft padding was used to stabilize the children's heads in order to minimize head motion. For the fMRI data, slices were recorded in ascending order, using a EPI sequence (52 slices, 2.19 × 2.19 × 2.2 mm voxel size, 2.2 mm slice thickness, 0.3 mm interslice gap, TR = 3,000 ms, TE = 29.8 ms, 90° flip angle, 96 × 96 acquisition matrix) and covered the whole brain (field of view: 210 × 210 × 130 mm). Each run consisted of 107 measurements. Furthermore, a high‐resolution T1‐weighted anatomical image (MPRAGE sequence, 182 slices, resolution 0.98 × 0.98 × 1.2 mm3, TE = 4.6 ms, 256 × 256 acquisition matrix, 8° flip angle, 250 × 250 × 218 mm field of view) was acquired for each participant.
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.
