Fifty years ago, Paul Lauterbur published his
groundbreaking Nature paper which established
zeugmatographyor magnetic resonance
imaging/MRIas a viable way to50 years MRI use
magnetic field and radiofrequency signals to
visualize objects. Lauterbur s first human MRI
scanner is located in the Illinois MRI Exhibit at
the Beckman Institute for Advanced Science and
Technology. He was recruited to the University of
Illinois Urbana-Champaign in the 1980s. He won
the 2003 Nobel Prize in Physiology of Medicine
for developing MRI with Sir Peter Mansfield, a
British physicist.

Since that time, MRI has become an essential tool
for doctors to view inside the body and see soft
tissue like the heart, brain and other muscles
and organs. MRI images help doctors understand
what is happening in disease. MRI lets you view
the status of tissue, observe shapes, blood flow,
inflammation and even the changing shape of soft
tissue. Because MRUI enables doctors to look
inside the body quickly and clearly, advanced
treatments have been developed which has led to
longer, healthier lives.

MRI is a flexible imaging technique, and MRI
scanners have continued to improve over the
years. The unit of measure for magnetic field
strength is Teslas. The earths magnetic field is
approximately 0.00005 Tesla. Lauterburs first
human MRI magnet was 0.09 Teslas. Thats about
2,000 times the Earths magnetic field. He was
able to see structures in the body, but the
resolutions were grainy and at low resolutions.

Todays MRI systems are 1.5T, 3T, but recently an
MRI magnet thats 7 Tesla was purchased by the
University of Illinois Urbana-Champaign and Carle
Hospital. Its 75 times stronger than Lauterburs
original magnet and allows us to localize
function in the brain down to 0.5 millimeters
with clarity and excellent contrast. MRI imaging
continues to evolve and improve, thanks to higher
magnetic field which provide even higher spatial
resolution images of the brain and body. New MRI
systems that are small and portable are now
available. Who knows what MRI imaging will
accomplish in the years to come?

Talk To An Expert
Over 40 million MRIs were performed in the U.S.
last year, and no doubt its use will continue to
grow. If youre in need of a new MRI scanner,
talk to the experts at Atlantis Worldwide. A used
or refurbished MRI system could provide you with
the performance you need, at a much lower price
pointand still deliver a beefy service
warranty. Contact Atlantis Worldwide today.
