Cardiac magnetic resonance (CMR) was performed on an Ingenia 3.0T MR system (Phillips Healthcare, Best, The Netherlands) using ECG gating. The default CMR protocol includes a steady-state pre-precession sequence using the balanced-fast-field-echo technique of left ventricular (LV) short-axis, four-chamber, two-chamber, and three-chamber views, late gadolinium enhancement (LGE), and native and contrast-enhanced T1 mapping. LGE was performed by the three-dimensional segmented-gradient-echo inversion-recovery sequence.
T1 mapping was performed using modified Look-Locker inversion recovery (MOLLI) in a 5-(3)-3 scheme (5 (link), 9 (link)). MOLLI was performed with breath-holding technique in mid-diastole in a single mid-ventricular short-axis slice (TR 2.2 ms, TE 1.8 ms, eight different TIs, matrix 152 × 150, field of view 300 × 300 mm2, flip angle 20°, SENSE 2, and 10-mm slice thickness).

All MRI data for this study was acquired using a Philips Ingenia 3.0T MR System (Philips Healthcare, Best, The Netherlands) with a 32-channel head coil at Cincinnati Children’s Hospital Medical Center. Structural images of the brain were acquired using the standard T1 weighted gradient echo sequence with the following scan parameters: TR = 10 ms, TE = 1.8, 3.8, 5.8, 7.8 ms, field of view = 256 × 224 × 200 mm, voxel size = 1 × 1 × 1 mm, number of slices = 200, flip angle = 8°, slice orientation = sagittal, and total scan duration = 4:42 minutes. Blood oxygen level-dependent (BOLD) fMRI data were collected using T2* weighted echo planar imaging sequence with multiband sensitivity encoding (SENSE) technique[26 (link),54 (link),83 (link)]. Scan parameters for the BOLD fMRI acquisition were as follows: multiband acceleration factor = 4, TR = 650 ms, TE =30 ms, field of view = 200 mm, flip angle = 53°, voxel size =2.5 × 2.5 × 3.5 mm, slice orientation = transverse (parallel to the orbitofrontal cortex line), slice thickness = 3.5 mm, number of slice = 40 (provided whole-brain coverage), number of volumes = 522, dummy scans = 12, and total scan duration = 5:42 minutes.

The structural and functional brain MRI scans were performed for a sub‐sample (n = 1304). Eligible participants were scanned either on the Philips Ingenia 3.0T MR System in Southwestern Lu Hospital (n = 1178) or the Philips Archiva 3.0T MR System in Liaocheng People's Hospital (n = 126). The core MRI protocol included the following sequences: sagittal 3D sT1W, axial T2W, sagittal 3D fluid attenuated inversion recovery (FLAIR), axial susceptibility weighted imaging (SWI), resting‐state functional MRI (rs‐fMRI), and axial magnetic resonance angiography (MRA).

Malignancy suspect lesions according to PI-RADS scoring were transrectally biopsied under stereotactic MRI-guidance with a Philips Ingenia 3.0T MR system using a dStream Torso body coil with Flex Coverage anterior and posterior coils that allow for a 32-channel, 60 cm body coverage (Philips North America Corporation, Andover, MA USA).
Briefly, a stereotactic needle-frame with x-y-z freedom was fixed onto the patient table. Target lesions were (re-)allocated and the sampling position was planned with the frame-dedicated software (DynaCAD, Invivo Corporation, Gainesville, FL, USA). The accurate position of the biopsy needle-tip was confirmed with a T2w TSE HR sequence.

Perfusion Imaging of Resting-State Brain

Check if the same lab product or an alternative is used in the 5 most similar protocols
All subjects underwent a PCASL scan on an Ingenia 3.0T MR system (Philips Medical Systems, Netherlands) with the application of a standard eight-channel digital head coil receiver. During the MRI scans, participants wore headphones and earplugs, and lied on their backs. A moderately tight, comfortable foam cushion was used to reduce head movement. In addition, participants were required to rest peacefully and close their eyes. All subjects fasted for at least 4 h. The resting-state perfusion imaging technique was conducted with the application of a PCASL sequence as follows: repetition time = 4000 ms; label duration = 1650 ms; echo time = 11 ms; flip angle = 90°; post-label delay = 1600 ms; field of view = 240 mm × 240 mm; slice thickness = 4 mm with 10% gap; matrix = 64 × 64; 20 axial slices; total scan duration = 4 min 08 s. Finally, each subject contained 60 volumes used as 30 label-control image pairs.

In-vivo Magnetic Resonance Spectroscopy of Cortical and Subcortical Brain Regions

Check if the same lab product or an alternative is used in the 5 most similar protocols
Magnetic resonance imaging took place at the molecular imaging center of Sherbrooke (CIMS), located at the CRCHUS. MRI and MRS data were acquired using a whole-body 32-channel head coil scanner (Ingenia 3.0 T MR system, Philips, USA). Each session began with the acquisition of anatomical images of the whole brain in T1-weighted contrast. These images were then used as a benchmark for the placement of the spectroscopic voxels of interest (VOI), in respect with the following parameters: VOI size = 20*30*30 mm3; VOI orientation: transverse. Two single voxel spectroscopy measurements were obtained, the first VOI was placed in the occipital cortex bilaterally, and the second VOI was placed on the basal ganglia’s globus pallidus of the left hemisphere (Fig. 2). The MEscher-Garwood Point RESolved Spectroscopy (MEGA-PRESS) sequence [40 (link)] was used to measure the signals of the metabolites of interest, applying the following parameters: TR (repetition time) = 2000 ms; TE (echo time) = 68 ms; Excite flip angle = 90°; Refocus flip angle = 180°. Water suppression was first performed applying a water-suppressing band at 4.7 ppm, using the excitation technique.

To estimate AT-MA length MRI scans were acquired. For this purpose, a 3T Philips scanner (Ingenia 3.0T MR system, Amsterdam, Netherland) was used. The participants laid on their sides, and the right ankle was set in a neutral angle position. The joint angles were measured with a goniometer to ensure the same joint position for each participant. Then the ankle was secured with sandbags to fix the joint during the scan. The scan was retaken with 15-degree plantar flexion angle position. The scans were performed using a T1 weighted turbo spin echo sequence (slice thickness 5 10 mm, slice gap 5 0 mm, slices scan order: interleaved, TR 5 650 ms, TE 5 20) at all measurements.

Multimodal MRI Acquisition Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
MRI scans were acquired with a standard whole‐head coil on a Philips Ingenia 3.0 T MR system. To prevent head motion, foam inserts surrounded the children's heads. The total scan protocol lasted 56 min, including two fMRI tasks, high resolution T2 and T1 scans, diffusion tensor imaging scans and a resting‐state fMRI scan. The order of the scans was the same for all participants and always started with the SNAT. The SNAT was projected on a screen that was viewed through a mirror on the head coil. Functional scans were collected during three runs T2*‐weighted echo planar images (EPI). The first two volumes were discarded to allow for equilibration of T1 saturation effect. Volumes covered the whole brain with a field of view (FOV) = 220 (ap) × 220 (rl) × 111.65 (fh) mm; repetition time (TR) of 2.2 s; echo time (TE) = 30 ms; flip angle (FA) = 80°; sequential acquisition, 37 slices; and voxel size = 2.75 × 2.75 × 2.75 mm. Subsequently, a high‐resolution 3D T1scan was obtained as anatomical reference (FOV = 224 (ap) × 177 (rl) × 168 (fh); TR = 9.72 ms; TE = 4.95 ms; FA = 8°; 140 slices; voxel size 0.875 × 0.875 × 0.875 mm).

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.
