8 channel head coil

Manufactured by GE Healthcare

Sourced in United States, United Kingdom

The 8-channel head coil is a piece of laboratory equipment designed for use in magnetic resonance imaging (MRI) systems. Its core function is to transmit and receive radio frequency (RF) signals from the patient's head during the MRI scanning process. The 8-channel design allows for the simultaneous acquisition of data from multiple regions of the head, improving the overall image quality and signal-to-noise ratio.

Infant Brain MRI Scanning Protocol

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

Infants were scanned within the first weeks of postmenstrual life (ie, the time elapsed between the first day of the pregnant women’s last menstrual period and the time of the MRI scan of their infant). Infants were fed, swaddled, and acclimated to the scanning environment and scanner noise by listening to a tape recording of the scanner sounds played before each pulse sequence. They were given time to fall asleep, without the use of sedatives, while lying on the scanner bed before the start of each sequence. Foam and wax ear plugs, along with ear shields (Natus Medical), were applied to dampen scanner noise. MRI-compatible electrocardiographic leads were placed on the infant’s chest, and a pulse oximetry sensor was placed on the infant’s toe. Heart rate and oxygen saturation were continually monitored during the scan (In Vivo Research). Images were obtained using a 3 Tesla Signa MRI scanner (General Electric) and an 8-channel head coil. Near the middle of the study’s data collection, the MRI scanner was upgraded. Details on pulse sequences can be found in the eAppendix in the Supplement.

Brain activation was measured by way of Blood oxygen level-dependent (BOLD) fMRI on a General Electric 3.0-Tesla Signa HDx scanner (General Electric Healthcare, Waukesha, WI) with 8-channel head coil. All scans took place at the Center for MR Research at the University of Illinois at Chicago. As described in Meyer et al. (2014) (link), images were acquired with 30 axial, 4-mm slices with no gap using a standard T2*-sensitive echo planar image sequence (1.5-s repetition time; 25-ms echo time; 64×64 matrix; 20-cm field of view; flip angle 90°). The duration of the scan session was approximately 1 hour and, in addition to the verbal memory test, included a simple reaction time, a working memory task and structural scans that were examined as part of previous studies (Rubin et al, 2015b ; Sundermann et al, 2015 (link)).

Functional MRI scanning was carried out using a 3 T GE Signa HDxT MRI scanner (General Electric) with 8-channel head coil at the VU University Medical Center (Amsterdam, The Netherlands). Functional data for the learning and transfer phase runs were acquired using T₂*-weighted echo-planar images with BOLD contrasts, containing ∼410 and 240 volumes for learning and transfer runs, respectively. The first two repetition time volumes were removed to allow for T₁ equilibration. Each volume contained 42 axial slices, with 3.3 mm in-plane resolution, repetition time = 2150 ms, echo time = 35 ms, flip angle = 80°, field of view = 240 mm, 64 × 64 matrix. Structural images were acquired with a 3D T₁-weighted magnetization prepared rapid gradient echo (MPRAGE) sequence with the following acquisition parameters: 1 mm isotropic resolution, 176 slices, repetition time = 8.2 ms, echo time = 3.2 ms, flip angle = 12°, inversion time = 450 ms, 256 × 256 matrix. The subject’s head was stabilized using foam pads to reduce motion artefacts.

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.
