16 channel breast coil

Manufactured by Philips
Visit Supplier
Sourced in Netherlands

The 16-channel breast coil is a specialized medical imaging device designed for use with Philips magnetic resonance imaging (MRI) systems. It is equipped with 16 individual receiver channels, which are used to capture high-quality images of the breast region. The core function of this coil is to enhance the signal-to-noise ratio and spatial resolution of MRI scans, providing healthcare professionals with detailed anatomical information to support accurate diagnosis and treatment planning.

Non-Invasive FEXI Imaging Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Imaging was performed on a Philips 3T Achieva TX scanner with 16-channel breast coil. The parameters of the FEXI protocol in vivo were: δ=10 ms, Δ=21 ms, tm = 12 (×2), 250 (×2) ms, bf = 0.3 ms/μm2, b = 0.044 (×3), 0.51 (×6) ms/μm2. Here ×2 means that the acquisition was repeated twice with the same parameter, and correspondingly for ×3 and ×6. The values of tm and bf were selected with an optimization minimizing noise propagation, assuming ADC values of 1.3–1.9 μm2/ms (8 ,15 (link)). FEXI was performed with diffusion encoding applied along three orthogonal directions. Seven 5 mm thick slices were acquired using EPI with 3×3 mm spatial resolution, TR = 3 s and total scan time of 6:06 min. Because standard fat suppression did not perform well, we isolated the water and fat signals by chemical shift separation.

The human imaging study was approved by the Institutional Review Board at Vanderbilt University Medical Center. Following written informed consent, seven female patients with breast cancer (age 55.3±8.0 years) with tumors ≥ 1 cm were recruited. All human imaging was performed on a Philips 3T Achieva MRI scanner using a 16-channel breast coil.

Breast MRI Protocol for Contrast Enhancement

Check if the same lab product or an alternative is used in the 5 most similar protocols
MRI examination was performed using a 3T system (Achieva, Philips Healthcare, Best, Netherlands) with a 16-channel breast coil and the patients were set in the prone position. The DCE study was performed using one pre- and five postcontrast fat-saturated axial T1-weighted images with a temporal resolution of 75 seconds. Subtraction images were made by postcontrast T1-weighted images minus precontrast T1-weighted images. Imaging parameters were as follows: repetition time / echo time (TR/TE), 4.92/2.46; flip angle, 10°; matrix size, 448 × 448; field of view (FOV), 360 × 360; slice thickness, 1.6 mm. Gadobutrol (Gadavist, Bayer, Germany) was injected IV at a dose of 0.1 mM/kg followed by a 20-ml saline flush at a rate of 2 ml/s for the dynamic contrast study. Subtraction images and kinetic analysis including color-coding map were processed by Dynacad (v. 2.1.7.113583, Philips Healthcare). Subtraction images were utilized in assessing the lesions.

Diffusion-Weighted Imaging of Breast Cancer

IMPULSED imaging was performed using a Philips Achieva 3T scanner with a 16-channel breast coil. Acquisition sequence parameters were TR/TE=4500/103ms; FOV=192×192mm; acquisition matrix size 96×96; reconstructed in-plane resolution = 1.3×1.3 mm; 10 or 20 slices; slice thickness=5 mm; single shot EPI; SENSE factor=3; half scan factor 0.64; WFS(pix) / BW (Hz) = 12.181/35.7; fat suppression with SPAIR; and dynamic stabilization was used to minimize DWI signal drifts during scanning. All diffusion sequence parameters were the same as in Table 2. The total scan time ≈ 7 mins. In addition, ADC measurements using PGSE acquisitions with Δ = 54 and 34 ms were performed to further investigate the ADC dependence on diffusion times.

FEXI Imaging Protocol for Breast MRI

Check if the same lab product or an alternative is used in the 5 most similar protocols
Imaging was performed on a Philips, Best, The Netherlands 3‐T Achieva TX scanner with a 16‐channel breast coil. The parameters of the FEXI protocol in vivo were as follows: δ = 10 ms; Δ = 21 ms; tm = 12 ms (×2), 250 ms (×2); bf = 0.3 ms/μm2b = 0.044 ms/μm2 (×3), 0.51 ms/μm2 (×6). Here, ‘×2’ means that the acquisition was repeated twice with the same parameter, and correspondingly for ‘×3’ and ‘×6’. The values of tm and bf were selected with an optimization minimizing noise propagation, assuming ADC values of 1.3–1.9 μm2/ms 8, 15. FEXI was performed with diffusion encoding applied along three orthogonal directions. Seven 5‐mm‐thick slices were acquired using echo planar imaging (EPI) with 3 × 3‐mm2 spatial resolution, TR = 3 s and a total scan time of 6 min and 6 s. Because standard fat suppression did not perform well, we isolated the water and fat signals by chemical shift separation.

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.
