12 channel volume head coil

Manufactured by Siemens
Sourced in Germany

The 12-channel volume head coil is a specialized piece of laboratory equipment designed for magnetic resonance imaging (MRI) applications. It features 12 individual radio frequency (RF) receiver channels that can be used to acquire data from the human head during an MRI scan. The coil is optimized for uniform signal reception across the entire head region, making it suitable for a variety of neuroimaging studies and clinical examinations.

3T MRI Neuroimaging Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
All subjects underwent an MR examination on a 3T MRI TRIO scanner (Siemens Medical Systems, Erlangen, Germany) equipped with a 12-channel volume head coil. The protocol of MR imaging included T1-weighted sagittal images obtained using a three-dimensional (3D) magnetization-prepared rapid gradient-echo (MPRAGE) sequence (echo time (TE)/repetition time (TR)/number of acquisitions (NA) = 4.63 ms/2300 ms/1, iPAT = 2, resolution 1 mm × 1 mm × 1 mm); T2-weighted transversal images obtained using 2D Periodically Rotated Overlapping Parallel Lines with Enhanced Reconstruction (BLADE) sequence (TE/TR/NA = 128 ms/5850 ms/1, 2 concatenations, iPAT = 1, resolution 0.6 mm × 0.6 mm × 3 mm); and T2-weighted sagittal images obtained using 3D Fluid Attenuated Inversion Recovery (FLAIR) sequence (TE/TR/NA = 318 ms/6200 ms/1, iPAT = 2, resolution 1 mm × 1 mm × 1 mm). MR images were visually assessed by neuroradiologists to preclude the presence of pathological changes.

Gradient echo EPI fMRI data acquisition was conducted at the Vaitkevicius Magnetic Resonance Centre on a 3T Siemens Verio system using a 12-channel volume head coil (TR: 2.6s, TE: 29ms, FOV: 256×256mm2, acquisition matrix: 128×128, 36 axial slices, voxel dimensions: 2 × 2 × 3mm3). In addition, a 3D T1-weighted anatomical MRI image was acquired (TR: 2200ms, TI: 778ms, TE: 3ms, flip-angle=13°, FOV: 256×256mm2, 256 axial slices of thickness = 1.0mm, matrix=256×256). A neuroradiologist reviewed all scans to rule out clinically significant abnormalities.

Functional MRI (fMRI) BOLD-contrast time series data collection was performed using gradient echo planar imaging (EPI) on a 3T Siemens Verio system using a 12-channel volume head coil (TR: 2.6 s, TE: 29 ms, FOV: 256×256 mm2, acquisition matrix: 128×128, 36 axial slices, voxel dimensions: 2×2x3 mm3). In addition, a 3D T1-weighted anatomical MRI image was acquired for each participant (TR: 2200 ms, TI: 778 ms, TE: 3 ms, flip angle=13°, FOV: 256×256 mm2, 256 axial slices of thickness =1.0 mm, matrix=256×256).

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.
