FDA Clears MAGNETOM Terra 7T MRI Scanner From Siemens Healthineers

  • World’s first 7T MRI scanner cleared for clinical imaging
  • Scanner has over twice the SNR of 3T MRI for higher resolution and
    faster acquisition times in clinical applications
  • 50 percent lighter 7T magnet integrates easily into clinical

MALVERN, Pa.–(BUSINESS WIRE)–The Food and Drug Administration (FDA) has cleared the MAGNETOM Terra
magnetic resonance imaging (MRI) scanner from Siemens Healthineers – the
first-ever 7 Tesla (7T) MRI cleared for diagnostic imaging. This
advanced ultra-high-field scanner produces cross-sectional images of the
head and knee, and is intended for patients over 66 lbs. The system’s
neurological and musculoskeletal (MSK) applications have the potential
to help physicians achieve unprecedented breakthroughs in clinical care
by revealing functional and anatomical details not visible at lower
magnet field strengths.

Building upon the company’s rich history as a leading provider of 7T MRI
to the global research community, the new MAGNETOM Terra possesses the
unique Dual Mode feature, which permits the user to switch for the first
time ever between an investigational “Research Mode” and a
510(k)-cleared “Clinical Mode” for imaging, while keeping research data
and clinical images safe on separate databases, respectively. The
scanner delivers superior images with up to 64 receive channels and more
than twice the signal-to-noise (SNR) ratio of 3T MRI in optimized
7Tneuro and MSK clinical applications. Its 80/200 gradients provide high
levels of power to not only perform diffusion MRI and functional MRI
(fMRI), but also to utilize the company’s Simultaneous Multi-Slice (SMS)
application to accelerate advanced neurological applications for
clinical routine. Its ultrafine 0.2 mm in-plane anatomical resolution
potentially enables visualization of previously unseen anatomical
structures. For example, cerebral cortex imaging at 0.2mm in-plane
resolution may yield never-before-visible clinical details in cortical
structure. And the scanner’s submillimeter BOLD fMRI contrast increases
linearly with field strength; this could translate, in clinical use, to
higher resolution in neuro imaging compared to 3T applications. The
scanner has two coils optimized for clinical neuro and knee imaging –
the first FDA-cleared applications for 7T MRI. The MAGNETOM Terra
leverages the syngo MR E11 software platform from Siemens
Healthineers, enabling users to work in the same manner as they would
with the company’s 1.5T and 3T technology. The MAGNETOM Terra also
features the hyper-fast image reconstruction technology of the MaRS
(Measurement and Reconstruction System) computer, for speeds up to 20
times faster than previous generations of 7T research scanners.

Possessing these and other unique features and capabilities, the
MAGNETOM Terra can be leveraged by healthcare institutions to grow their
professional and academic reputations, attract and retain premier
talent, secure highly coveted research grants, and maintain their
competitive edge.

“With the MAGNETOM Terra 7T scanner, Siemens Healthineers proudly
introduces the first MRI field strength above 3T to be cleared for
clinical imaging in nearly 20 years,” said Christoph Zindel, MD,
Senior Vice President and Head of Magnetic Resonance at Siemens
Healthineers. “Armed with the MAGNETOM Terra’s ultra-high-field
strength, clinicians may be able to achieve new, unforeseen levels of
patient care and clinical advancements through improved visualization of
a wide variety of neurological disease states.”

The MAGNETOM Terra is constructed from top to bottom by Siemens
Healthineers – the first time every major component of a 7T scanner has
been manufactured entirely by one equipment vendor. Addressing concerns
regarding helium availability, the MAGNETOM Terra has a Zero Helium
boil-off feature that reduces evaporation in both standby and
operational modes. And the scanner’s brand-new magnet, which is 50
percent lighter than any 7T magnet produced to date, can be shipped cold
via airfreight and integrated more easily into clinical environments,
even on upper floors.
