Standard head coil

Manufactured by Siemens

Sourced in Germany

The Standard head coil is a key component of Siemens' medical imaging equipment. It is designed to function as the signal receiver for magnetic resonance imaging (MRI) scans, capturing the electromagnetic signals generated by the body's hydrogen protons when exposed to a strong magnetic field. The coil is engineered to provide consistent and reliable performance, enabling healthcare professionals to obtain high-quality images for diagnostic purposes.

The local institutional review board approved all procedures and all participants provided informed consent before data collection commenced. As part of a larger study, all participants completed a neuropsychological battery designed to characterize their functioning on tests of memory and processing speed. The following battery was given during a baseline visit.
After approximately one week (M=7.1 days, SD=0.9, range=6 – 11), the HVLT-R, BVMT-R, SDMT, TMT-A, and TMT-B were repeated. The same form of each test was used to maximize practice effects.
MRI was acquired on a Siemens Trio 3.0T scanner with a standard head coil (Siemens, Erlangen, Germany). The imaging protocol was a sagittal 3D magnetization prepared rapid acquisition gradient-echo (MPRAGE) T1-weighted acquisition (inversion time=1000 ms, echo time=2.08 ms, repetition time=2400 ms, flip angle=8 degrees, field of view=224 mm, slice thickness=0.7 mm, 256 slices). All MRI scans were processed on the same workstation using FreeSurfer image analysis suite v5.3.0 (http://surfer.nmr.mgh.harvard.edu/) to estimate total intracranial and hippocampal volumes. Technical details are described previously [22 (link)–24 (link)]. Hippocampal volumes were normalized to total intracranial volume.

All measurements were acquired with a Siemens Magnetom Vision 1.5 T whole body MRI system with a standard head coil (Siemens, Erlangen, Germany).
Functional imaging was performed using a T2*-weighted gradient-echo EPI mosaic sequence with TE = 60ms, TR = 4000 ms, FA = 90°, 23 slices covering the whole brain, slice thickness = 5mm, interslice distance = 1mm. The matrix size was 64x64 and field of view (FOV) 240 mm with in-plane resolution 3.75x3.75 mm². Each scanning session included the acquisition of a high resolution TI-weighted 3D scan with a voxel size of 1 × 1 × 1 mm³ and a FOV of 256 × 256 mm. A magnetization-prepared rapid acquisition gradient-echo (MP-RAGE) technique was employed. The scan covering the whole brain lasted for 10 minutes and 52 seconds. Furthermore, a T2-weighted and proton density scan was acquired for clinical routine evaluation.

Functional MRI data were acquired using a Siemens 3.0 T Trio scanner with a standard head coil at the Key Laboratory of Cognition and Personality (Ministry of Education) of Southwest University (China). A whole‐brain gradient‐echo, echo‐planar‐imaging sequence was used for functional scanning with a repetition time (TR) of 1,500 ms (29 ms echo time, 25 5.0‐mm‐thick slices with 0.5 mm interslice gaps, 3 × 3 mm in‐plane resolution, field of view 192 × 192 mm, matrix 64 × 64; flip angle = 90°). A high‐resolution, T1‐weighted structural image (1 mm³ isotropic voxel MPRAGE) was acquired after functional imaging.

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.
