Parallel echo planar imaging (EPI) using GRAPPA is making it possible to overcome high field challenges in MRI. It can now be run in single shot as well as segmented mode at very high image quality.

Ultra Short Echo Time Imaging

Ultrashort echo time (UTE) pulse sequences are sensitive to the presence of short T2 relaxation components in tissue produced by iron deposition and other processes. They give a new insight into brain or bone structures with an interesting potential for clinical diagnosis.
 

  • New contrasts in MRI using ultra short echo time
    imaging (UTE)
  • Radial imaging techniques
  • Minimal echo time of less than 300 μs
     

Fourier Flow Imaging

The fast Fourier flow method of magnetic resonance (MR) imaging offers a fast and efficient way of measuring quantitative flow. A detailed examination of flow profiles is possible even in smaller vessels.
 

  • Quantitative Fourier Flow Imaging
  • Based on phase contrast angiography
  • Multi dimensional data evaluation

Parallel Routine Imaging

With ParaVision 5.0 parallel imaging is available for all imaging techniques including echo planer imaging (except spiral imaging).
 

  • Reduced scan times
  • Higher animal throughput
  • Integrated reference scan
  • Improved spatial resolution
