High-resolution, in-phase and out-of-phase imaging – in just one breath-hold using 3D Dual Echo for Signa HDxt

In- and out-of-phase imaging in abdominal MRI identifies fatty infiltration, focal fatty sparing, liver lesions and other conditions. Images are generally acquired in separate breath-holds, causing suboptimal image registration. And with current 2D techniques, full liver coverage usually requires 6-8 mm slices with 1-2 mm inter-slice gaps – compromising image quality

Cube replaces several slice-by-slice, plane-after-plane 2D acquisitions with a single 3D volume scan. So a Cube 3D isotropic image gives you every bit of information you need for evaluating even the smallest lesions. You can easily reconstruct high-definition, sub-millimeter-resolution images from a single Cube acquisition into any plane you desire – without gaps and with the same resolution as the original plane in which it was acquired. And because the entire 3D story is captured in one time-efficient scan, you save exam time.

3D Dual Echo is a new sequence that produces in-phase and out-of-phase images in the
same acquisition within a single breath-hold. It ensures perfect registration between
corresponding images every time, and greatly enhances small lesion detection and
visualization — giving you uncompromised image quality.

At 3.0T, it is now possible to capture the first out-of-phase TE and the in-phase TE in a
single acquisition, resulting in optimal tissue contrast. This represents a significant step forward
in the clinical utilization of 3.0T for body imaging.


One acquisition

3D Dual Echo acquires images in one breath-hold versus two, to increase your productivity and throughput.


Greater confidence

With 3D Dual Echo, you consistently obtain higher-resolution, perfectly co-registered images to improve your diagnostic confidence.


Easier exams

3D Dual Echo reduces breath-hold failures, slice mismatches, retakes and exam difficulty – and shortens scan times for critically ill patients.

BENEFITS

  • Acquire perfectly co-registered images every time for optimal contrast.
  • Eliminate interslice gaps for uncompromised small lesion detection and visualization.
  • Minimize partial volume effects with improved through plane resolution of approximately 4 mm.
  • Increase SNR up to 30% (compared to 2D equivalent technique) for higher spatial resolution.
  • Perform multi-planar reformats and reconstructions with flexibility and ease.
