GE Healthcare showcased the SIGNA Premier wide bore 3.0T magnetic resonance imaging (MRI) system at the 25th International Society of Magnetic Resonance Imaging (ISMRM) Annual Meeting. It is 510(k) pending at U.S. FDA. It is not available for sale in the United States and may not be commercially available in other regions.
SIGNA Premier is the result of a four-year collaboration with the NFL and research institutions around the world working to design new imaging tools. SIGNA Premier delivers a new level of performance with research-focused clinical capabilities designed particularly for neurological and oncology research and clinical work.
“The image quality we have seen to date from the SIGNA Premier is excellent and very consistent,” says Scott Reeder, M.D., Ph.D., vice chair of research and chief of MRI at University of Wisconsin-Madison.
The University of Wisconsin-Madison, is testing a research system of SIGNA Premier and has scanned approximately 100 subjects to date.
“The high-fidelity gradients and RF systems of a scanner are key to obtaining high-quality, repeatable, and reproducible quantitative measurements; this is increasingly important as we move from qualitative to quantitative imaging. SIGNA Premier combines the advantages of a wide bore system with an ultra-high-performance system and in some instances, is outperforming other ultra-high-performance systems with smaller bore sizes, particularly for diffusion-weighted applications. I believe the wide bore is going to improve access and comfort for patients at our hospital. We have also been able to improve the spatial resolution with very similar SNR performance as other ultra-high-performance systems.”
This system is built on a platform with: a short-bore, high-homogeneity magnet; powerful new gradients; a new digital RF transmit and receive architecture; and cutting-edge applications, including cloud analytics. SIGNA Premier is powered by the innovative SuperG gradient technology to improve diagnostic confidence for clinicians. The SuperG gradient coil introduces outstanding performance and superb stability, which is designed to deliver the performance of ultra-high-performance, research-class 60 centimeter MRI system in a 70 centimeter bore MRI.
The RF technology of SIGNA Premier is designed to provide greater clinical performance and higher overall image quality especially for data-intensive applications, based on GE’s Total Digital Imaging (TDI) architecture. A total of 146 independent channels allow the simultaneous combination of multiple ultra-high channel count surface coils for faster accelerations and uncompromised image clarity.
The TDI 48-channel Head Coil delivers clinical performance for virtually every patient. A fitadaptable design addresses 99.99 percent of the population – including extremely large heads and short necks – while preserving high signal-to-noise ratio (SNR) and outstanding and sustainable image quality.
