MR EXCITETM:
The Biggest Breakthrough Ever In MRI
Speed has long
been the #1 challenge in MRI. How can you acquire information fast
enough to overcome or to capture the movement of the human body? In
1985 we revolutionized Magnetic Resonance Imaging with Signa®
high-field technology. We are proud to introduce EXCITETM,
that will now redefine MRI performance standards.
EXCITETM is the industry’s
first radical redesign of the MRI data pipeline. The first
end-to-end solution that optimizes each and every component in the
imaging chain. This technology is available on new or installed
scanners across the Signa family. It is designed to give you
unprecedented clinical flexibility, with deep reserves of speed,
resolution and SNR. EXCITETM is the industry’s first
comprehensive technical solution to improving speed in MRI from
image acquisition to final image presentation. In re-engineering the
MRI data pipeline, we optimized every component in the imaging
chain, from signal (pulse sequence) transmission to data
processing. And here’s how we achieved it.
TRANSMISSION ...
lightning-fast pulse sequences : EXCITETM delivers the
shortest pulse sequence parameters currently available. Shorter TRs,
TEs, and EPI echo spacings translate to faster acquisition, higher
SNR, and significantly better image quality.
RECEPTION ... 16
quadrature (8 independent), expandable channels with coils to match:
EXCITETM has superior acquisition and digitization
capabilities, including:
• Multi-channel coils optimized
for parallel imaging techniques.
• High-bandwidth independent
receivers, essential for today’s short echo-spacing,
echo-planar and short TR/fast gradient echo-sequences.
• Expandable quadrature receive channels. The modular
expandability of EXCITETM technology positions it well
for today’s parallel imaging techniques.
PROCESSING ... the
power and speed to eliminate bottlenecks. Increasing the bandwidth
and number of channels receiving data is only half the equation. You
need a processing engine that is robust and fast enough to deal with
this flood of information. No matter how data-intensive the
procedure, there are no slow-downs and no bottlenecks in the
pipeline. With EXCITETM,
the interval between acquiring the data and seeing the image has
been virtually erased.
In effect, EXCITETM
expands MRI from a three-dimensional modality to a true
four-dimensional tool. It’s
a quantum leap in acquisition speed and image quality. Imagine how
the benefits of MRI could be extended to more patients, particularly
geriatric, pediatric, and trauma cases.
Imagine how patients will feel when
they can breathe freely - and breathe easier with shorter exams. And
consider the advantage on patient care, throughput and revenue
opportunities.
The DiscoveryTM
Family
Gives you choices among Hybrid Imaging Systems
For large institutions and research
centers:
The Discovery LS combines two
industry- leading products - the LightSpeed Plus
CT scanner and the Advance NXi PET scanner - to satisfy the most
demanding needs. The Discovery LS can function independently as a
PET scanner or CT scanner.
PET & SPECT in a single system:
The Discovery VH is especially
important for Nuclear Medicine departments. The VH is the only gamma
camera combined with a CT system. The 1-inch crystal detector
delivers high-quality, low-energy SPECT and high-energy PET studies
- both inherently fused with
CT images.

Clinicians who
have worked with it tell us that this is the future of MRI... that someday
all systems will perform like this.
EXCITETM
is a major advance in MRI.
It overcomes the speed bumps in pulse programming... accelerates download
times and image reconstruction.. and provides huge advantages for parallel
imaging.
Dr. Robert
R Edelman, MD, Chairman,
Dept of Radiology, Evanston Northwestern Healthcare, Professor of
Radiology, Northwestern University Medical School.
For the first time we have the opportunity to capture images at the speed
of life. GE EXCITETM
makes MR studies more comfortable for patients, especially those who have
difficulty holding their breath in
certain abdominal procedures.
Dr.
Lawrence N. Tanenbaum, MD,
Section Chief MRI,
CT and Neuroradiology, New Jersey Neuroscience Institute, Edison Imaging -
JFK Medical Center.
The
breakthrough is in the way EXCITETM combines image quality and
temporal advantages synergistically. I don’t see an end to the
possibilities.
Dr. Emmanuel
Kanal, MD,
FACR, Professor
of MR Services,
Dept of Radiology,
University of Pittsburgh Medical Center.
There
is a ton of signal to noise.
And the images come up extremely fast. I see this system as a way to
attack my patient backlog.
Dr. Alfio
Pennisi, MD,
