Magnetom verio syngo

Manufactured by Siemens
Sourced in Germany

The Magnetom Verio Syngo is a magnetic resonance imaging (MRI) system produced by Siemens. It is designed to provide high-quality medical imaging for diagnostic and research purposes. The Magnetom Verio Syngo utilizes a 3 Tesla superconducting magnet and advanced imaging technologies to capture detailed images of the body's internal structures.

Standardized Infarct Volume Calculation

All patients underwent standard neurological and general medical evaluation and assessment on the basis of the NIHSS score at 7 days and the modified Rankin scale (mRS) at 90 days after stroke onset.
Magnetic resonance imaging (MRI images were acquired within 72 h of stroke onset on a 3.0 T Magnetom Verio Syngo instrument (Siemens, Munich, Germany). The radiologist used diagnostic workstations with a unisight system for interpretation and measurement of the infarct volume. The analysis was performed blind to the clinical history, physical findings, patient identity, and final diagnostic results. The total infarct volume was calculated on the basis of the infarct size on the diffusion-weighted imaging sequence and then multiplied by the thickness. All image data were standardized according to intracranial cross-sectional area18 (link). The formula of the volume standardization of cerebral infarction was as follows: infarct volume × mean of intracranial cross-sectional area/intracranial cross-sectional area of patient.

MRI data from the Human Connectome Project (http://www.humanconnectome.org/) were collected on a 3 T Siemens Connectome Skyra, including a T1-weighted MPRAGE structural scan, resting-state functional MRI and DTI using multiband acquisitions.
MRI data from a separate cohort of TBI patients and healthy control subjects, were acquired using a 3 T Siemens Magnetom Verio Syngo with a 32-channel head coil. Standard clinical MRI was collected. Resting-state functional MRI data were also acquired, alongside a high-resolution T1-weighted image and DTI (see Supplementary material for details on the acquisition parameters for both cohorts).

Standardized Cerebral Infarct Volume Measurement

Check if the same lab product or an alternative is used in the 5 most similar protocols
All patients underwent standard neurological and general medical evaluations and assessments using the modified Rankin scale (mRS) and Barthel Index (BI) at admission, and 7 days after stroke onset. MRIs were acquired on a 3.0T Magnetom Verio syngo (Siemens, Germany). Radiologists with over 15 years of experience who were blinded to the clinical histories, physical findings, patient identities, and final diagnostic results used diagnostic workstations with the Unisight system to interpret and measure infarct volumes. The total infarct volume was calculated by the infarct size on the diffusion-weighted imaging sequence and then multiplied by the thickness. All imaging data were standardized by Cross-Sectional Area Intracranial.[13 (link)] The formula of the volume standardization for cerebral infarction is as follows: Infarct volume × mean intracranial cross-sectional area/the intracranial cross-sectional area of the patient.

fMRI Study of Pain Perception

Each participant underwent MR examination using a 3-T MAGNETOM Verio Syngo MRI scanner (Siemens, Erlangen, Germany) to allow functional T2*-weighted and anatomical T1-weighted image acquisition. Each patient’s head was fixed by tape on the forehead and a sponge on both sides of the face to prevent movement during MR examination. Whole-brain functional images were obtained using gradient echo-planar imaging sequencing, with a 3000-ms repetition time (TR); 30-ms time of echo (TE); 90° flip angle; 216-mm field of view (FOV); and 3 mm × 3 mm × 3-mm voxel resolution. Sampling consisted of 36 slices, 3 mm thick, with no gap, parallel to the anteroposterior commissure line. For each task series, 110 consecutive image volumes were acquired, including a 60-s rest, 30-s insertion (task), and 240-s recovery period.
Before functional data were acquired, anatomical images were obtained using a T1-weighted magnetization prepared rapid acquisition gradient echo (MPRAGE) sequence: (TR/TE/TI=2 500 ms/2.48 ms/900 ms, flip angle = 8°, FOV = 256 × 256 mm2, voxel size = 1 mm × 1 mm × 1 mm, 192 slices, no gap).
Each participant was asked to evaluate the maximal pain during the task and the degree of residual discomfort after MR examination using the VAS.

Structural MRI was acquired using a 3 T Siemens Magnetom Verio Syngo scanner with a 32-channel head coil. All participants were scanned using the same acquisition parameters. Structural MRI included a high-resolution T1-weighted MPRAGE (106 1-mm thick transverse slices, repetition time = 2300 ms, echo time = 2.98 ms, flip angle = 9°, in-plane resolution = 1 × 1 mm, matrix size = 256 × 256, filed of view = 25.6 × 25.6 cm), diffusion weighted imaging (64 directions, b = 1000 s/mm2 with four interleaved b = 0 s/mm2, echo time/repetition time = 103/9500 ms, 64 contiguous slices, field of view 256 mm, voxel size 2 mm3) and FLAIR to identify focal lesions.

Scanning used a 3T Siemens Magnetom Verio Syngo with a 32-channel head coil. Scanning session for each participant generated a structural high-resolution image T1-weighted MPRAGE image (106 1-mm thick transverse slices, TR = 2300ms, TE = 2.98ms, FA = 9°, inplane resolution = 1x1mm, matrix size = 256x256, field of view = 25.6cmx25.6cm), a diffusion-weighted image (64 directions, b = 1000s/mm2, 4 x b0 = 0s/mm2, TE/TR = 103/9500ms, 64 contiguous slices, FoV = 256mm, voxel size = 2mm3) and a T2 fluid-attenuated inversion recovery (FLAIR) image for lesion identification. The b0 volume used consequently is an average.

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.
