Ge 3t mri scanner

Manufactured by GE Healthcare

Sourced in United Kingdom, United States

The GE 3T MRI scanner is a high-field magnetic resonance imaging (MRI) system that uses a 3-tesla (3T) superconducting magnet to generate detailed images of the human body. The 3T MRI scanner is designed to provide high-quality images for a wide range of clinical applications, including neurology, orthopedics, and body imaging.

Resting-State fMRI and Structural Brain Imaging

All MRI images were collected using a GE 3T MRI scanner (GE Medical Systems, Milwaukee, WI) equipped with a standard head coil. Participants were asked to remain awake, relaxed, keep their eyes closed, and not to do any specific thinking during functional data collection. Conventional imaging sequences, which included T1-weighted images and T2-FLAIR images, were acquired for each subject to detect clinically asymptomatic lesions.
Using an echo-planar imaging (EPI) sequence, the rs-fMRI data were obtained with the following parameters: repetition time (TR)/echo time (TE) = 3,000 ms/40 ms, flip angle = 90°, 25 slices, thickness/gap = 5/0 mm, matrix size = 96 × 96, and field of view = 24 × 24 cm, 128 time points. Each scan lasted ~6 min.
Three-dimensional brain high-resolution T1-weighted structural images were acquired using a 3D magnetization-prepared rapid-acquisition gradient-echo (3D-MPRAGE sequence). The parameters are as follows: 176 sagittal slices, TR = 5.6 ms, TE = 1.7 ms, matrix = 256 × 256, (FOV) = 25.6 × 25.6 cm, and thickness/gap = 1.2/0 mm. This session lasted for ~5 min.

High‐resolution anatomical images of the whole brain were acquired on a GE 3T MRI scanner (GE Healthcare, Buckinghamshire, United Kingdom). T1‐weighted scan used a spoiled gradient echo (SPGR) with the following parameters: TR = 6.2 ms, TE = 2.8 ms, flip angle = 8, field of view (FOV) = 240 mm, slice thickness = 1.2 mm, matrix size =256 × 256 and total slices = 142. During the scanning process, each subject lay on his back on the scanner bed and was asked to remain still during the imaging process.

MRI examinations were performed on all subjects using a GE 3T MRI scanner (GE Medical Systems, Milwaukee, WI) equipped with a standard 8-channel head coil. Conventional imaging sequences, which included T1-weighted images and T2-FLAIR images, were acquired for each subject to detect clinically asymptomatic organic lesions. Subsequently, three-dimensional brain high-resolution T1-weighted structural images were acquired using a 3D magnetization-prepared rapid-acquisition gradient-echo (3D-MPRAGE sequence) with the following parameters: repetition time (TR) = 5.6 ms, echo time (TE) = 1.7 ms, ip angle(FA) = 15°,matrix = 256×256, eld of view (FOV) = 25.6 cm × 25.6 cm, and thickness/gap = 1.2/0 mm. This session lasted for approximately 5 min and 15 sec. DTI images were obtained using a singleshot echo-planar imaging (EPI) sequence with 64 diffusion gradient directions (b = 1000 s/mm 2 along 64 non-collinear directions) and a reference image (b = 0 s/mm2). The parameters were as follows: TR = 8700 ms, TE = 70.8 ms, thickness/gap = 3/0 mm, FOV = 24 cm × 24 cm, matrix = 128×128. Each scan lasted approximately 9 min and 16 sec.

Cerebral Aneurysm Imaging with Multi-Modal MRI

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

Images are routinely acquired with a 3T Siemens MRI scanner (Siemens MAGNETOM Skyra, Munich, Germany). The HR-VWI protocol included a 3D T1-weighted SPACE fast-spin-echo (FSE) and a 3D T2-weighted sequence. Five minutes after intravenous injection of 0.1 mmol/kg gadolinium-based contrast agent (Gadavist, Bayer Pharmaceuticals, Whippany, NJ), a post-contrast 3D T1-weighted SPACE FSE sequence and a contrast-enhanced magnetic resonance angiography (CE-MRA) were obtained. The reproducibility of results was tested on a 3T GE MRI scanner (GE Healthcare, Chicago, IL) in 9 UIAs which underwent additional HR-VWI. Three UIAs underwent a third scan on a 7T GE MRI (GE Healthcare, Waukesha, WI). Technical parameters used for imaging acquisition on each scanner are described in the Supplementary Tables 1–3.

Resting-state fMRI data were acquired on a 3-T GE MRI scanner (GE Medical Systems, Erlangen, USA) with an 8-channel GE head coil. High-resolution T1-weighted anatomical images were acquired using the magnetization-prepared rapid gradient echo (MPRAGE) sequence (TR/TE = 2000 ms /1.75 ms; flip angle = 15°; slice thickness = 1.0 mm; FOV = 240 × 240 × 160 mm³; resolution matrix = 256 × 256; voxel size = 0.94 × 0.94 × 1 mm³) for coregistration with the functional images. Using a T2*-weighted gradient-echo-planar imaging sequence, 180 functional volumes were acquired (slice number/TR/TE/flip angle = 40/2000 ms/30 ms/90°, matrix = 64 × 64, FOV = 225 × 225 × 140 mm³, voxel size = 3.52 × 3.52 × 3.5 mm³). Participants were instructed to stay awake with their eyes open and focus on the cross in the middle of the screen for the entire duration of the resting-state scanning, which lasted for a total of 6 min.

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.
