GE’s 3T MRI Gives up to 60 Percent More Coverage

GE received FDA clearance for its new Signa MR750 3.0T scanner that delivers up to 60 percent additional anatomical coverage and resolution unit per time, also allowing for up to five times the imaging performance over previous generations.
The system aims to extend the freedom for advanced application development, including a routine liver exam in 15 minutes and a full breast exam in two sequences. The Signa MR750 boasts a newly designed RF transmit system, maximizing performance with a 17 percent gain in scanning efficiency. In addition, the system includes the GE-exclusive Optical RF technology that reportedly adds up to 27 percent higher signal-to-noise ratio (SNR) over conventional, nonoptical MR receivers by reducing electrical noise and increasing signal detection.
When combined with GE’s use of high-density surface coils, the optical receive chain is said to be a critical path for ensuring clear signal reception and data analysis.
