Visit Supplier
Sourced in Netherlands

The 8-channel receive head coil is a specialized medical imaging device designed for use with Philips' magnetic resonance imaging (MRI) systems. It is a critical component that enables the acquisition of high-quality MRI images of the human head and brain. The coil is equipped with eight individual receiver channels, which allows for the simultaneous collection of data from multiple regions of interest within the scanned area, improving signal-to-noise ratio and image quality. This device is an essential tool for medical professionals in various fields, such as neurology, radiology, and research, who rely on advanced MRI techniques to diagnose and monitor various neurological conditions.

Multimodal MRI Acquisition and Analysis

MRI data were acquired on a 3-Tesla Philips Achieva Scanner (Amsterdam, Netherlands) with 8-channel receive head coil, full details are reported in Suo et al. (2016) (link). Structural measures were derived from 3 D-T1TFE sequences (1 mm isotropic resolution, TR/TE/FA = 5.39 ms/2.43 ms/8°). Functional connectivity (FC) was analysed from resting-state fMRI (rsfMRI), T2* echo-planar BOLD sequences acquired with eyes closed (FOV = 250 × 250 mm, matrix size = 64 × 64, 29 slices, slice thickness = 4.5 mm, TR/TE = 2000/30 ms, 200 volumes).

Multimodal Neuroimaging Protocol for Stroke Assessment

At both institutions, 3 T MRI data were acquired on a Philips Ingenia MRI scanner. One institution used an 8‐channel receive head coil for the brain MRI scans, and the other a 32‐channel head coil (Philips, Best, The Netherlands). At 3 T MRI a T1‐weighted image (T1WI) (1.0 mm × 1.0 mm × 1.0 mm resolution; echo time/repetition time (TE/TR) = 4.5/7.9 msec; flip angle = 8°; sense factor = 2; field of view (FOV) = 256 mm × 256 mm × 192 mm) and a spin echo fluid‐attenuated inversion recovery (FLAIR) (1.0 mm × 1.0 mm × 1.0 mm resolution; TE/TR = 275/4800 msec; flip angle = 90°; inversion time = 1650 msec; sense factor = 2; FOV = 224 mm × 224 mm × 160 mm) of the brain was acquired. These images enabled delineations of white matter and infarcts, respectively, which were automatically performed using the Quantib Brain Segmentation Tool (Quantib. B.V., Rotterdam, The Netherlands). To ensure complete inclusion of infarction zones, the infarct masks were dilated with a 3 mm × 3 mm kernel.
In addition, a T1WI and 2D PC data were recorded for PWV measurements (scan parameters are provided below) as well as a cine steady‐state free precession (SSFP) sequence (scan parameters are provided below) for LVSV measurements.

MRI scans were performed on a 3 Tesla Achieva Philips MRI scanner (Philips Healthcare, Best, The Netherlands) equipped with an 8-channel receive head coil. MRI scan protocol consisted of (a) Axial 3D T1-weighted images (FOV: 224 × 177 × 144, resolution: 0.88 × 0.88 × 1.20 mm3, TR/TE = 9.75/4.59 ms); (b) Sagittal FLAIR images (FOV: 220 × 173 × 220, resolution: 0.98 × 0.98 × 1.12 mm3, TR/TE/TI = 4800/274/1650 ms); (c) Axial Diffusion Tensor Images (DTI) (FOV: 224 × 224 × 120, resolution: 2 × 2 × 2 mm3, TR/TE = 8500/95 ms, one b = 0 s/mm2 volume and 15 diffusion-weighted volumes with a b-value of 1000 s/mm2); (d) Axial MTI (FOV: 230 × 230 × 132, resolution: 1.44 × 1.44 × 1.5 mm3, TR/TE = 57.07/10.00 ms, flip angle: 15°, two sets of images acquired with and without a sinc-gauss radio frequency saturation pulse of 25 ms duration, peak B1 amplitude of 5.283 µT and offset frequency of 2000 Hz).

Phantom scans were performed on a 3 T Achieva (Philips, Cleveland, Ohio) with a 2-channel transmit body coil and an 8-channel receive head coil. T1, T2, B1, and B0 mapping were performed by multi-inversion recovery, multi-echo, dual TR, and WASSR [58 (link)], respectively (sequence details can be found in the online supporting information). CEST and vCEST sequence details were as follows: CEST [3D SPGR with 75 ms 1μT and 3.5μT sinc-gauss pulses, TR=152 ms, 49 offsets from −5 to 5 ppm and one S0 image at −100kHz]; vCEST [3D SPGR with 75 ms sinc-gauss pulses, peak amplitude varying by 1μT/1ppm with 0.21μT at 0ppm, TR=152 ms, 49 offsets from −5 to 5 ppm and one S0 image at −100kHz]. These sequences were rapid 3D steady-state (similar to pulsed MT [59 (link)] and pulsed CEST [14 (link)]) reading one k-space line per saturation pulse. CEST at 1μT and 3.5μT were studied to match the amplitude of the vCEST (1μT) and to demonstrate more optimal saturation amplitudes for hydroxyl protons. The FOVs for all phantom studies were 190×190×9 mm and voxel size 1.5×1.5×3 mm, except the B1 map voxel size 3×3×3 mm. T1 and T2 were calculated by fitting the inversion recovery and spin echo signal equations for each voxel.

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.
