If you cant find a
decent reason or excuse to attend a major medical imaging meeting in Hawaii, then your
priorities are in serious need of adjustment. The International Society of Magnetic
Resonance in Medicine (ISMRM) recently held its 10th annual meeting in Honolulu, Hawaii,
from May 18 to 23, 2002. This meeting of imaging specialists focused exclusively on the
science and medical applications of advanced MRI for a solid six day period, with only an
occasional beach break. At least, thats my official version of the meeting.
So, with my sunscreen, exhibit guide and abstract book in hand, I set out to discover
the coming attractions that mainstream radiology departments can expect to hear more about
during the run-up to budget season and RSNA this year and next.
3T Systems
Citius, Altius, Fortius the Olympic motto of faster, higher, stronger
should be the new standard as high-field imaging has arrived, and you should begin
preparing to find a home for your tired, old 1.5T system. 3T is now officially ready to
roll, and no respectable prestigious radiology department can afford to do without one if
they strive to remain part of the 21st century. 3T systems deliver higher quality images,
acquired at faster speeds, with particular application to brain and cardiovascular
imaging.
Beginning with the opening session, almost all of the main presentations at ISMRM
focused on high-field imaging. The technological challenges associated with this increased
field strength primarily revolve around control of the static and switched fields and RF
energy levels that must be controlled for patient safety. Solutions to these challenges
are well underway, which will then leave users with significant benefits, primarily
improved spatial resolution (from higher SNR), faster scan times and new imaging protocols
(including spectroscopy applications) for advanced studies.
Since this will be the first generation of 3T for mainstream clinical use, expect that
the rate of change (need for upgrades) will be fast for this imaging platform, as coils,
pulse sequences, image processing SW and gradients are each modified and improved to
further harness the raw power of these systems. You may want to plan a healthy budget for
upgrades during the first few years if you decide to jump on this bandwagon anytime before
2004.
You should expect to see an initial wave of orders as the early adopters with
plenty of budget and research to accomplish put these systems through their paces
of the routine and rare cases. There is no need for a financial justification for clinical
use of these systems yet. There is a compelling confidence that the clinical world
of brain disease will receive a tremendous boost from the use of these systems to better
characterize disorders that require both metabolic and anatomic evaluations.
Squiggly Lines
Have you ever looked at MR spectroscopy (MRS) studies? Well, youre not
alone if you havent. In essence, with MRS you are looking at bio-chemical data, not
the usual sharp high contrast anatomical image that is the normal result from an MRI
system.
If you work in a radiology department, you are definitely ahead of most groups if you
already make regular use of MRS to diagnose neurological diseases and disorders. The
clinical utility is well proven, the reimbursement is in place, the benefits for patient
care are solid, and the techniques are push-button. Now we just need more education of
physicians (and especially radiologists) in order to broaden the use of these procedures.
Take some time to improve your knowledge of this area, as it is becoming an even more
important part of the MRI portfolio for state-of-the-art work.
Even Higher Fields
As 3T systems begin their move from the clinical research frontier into
mainstream clinical use, there is (obviously) something to take its place. Make room for
the new 7T and 9T MRI systems, which are now beginning to take hold in the basic research
world. MRI is now making its way into drug research and trials, even pre-clinical work
with animal studies.
Memo to Grads - Physics!
Given the paltry graduation rate of advanced degrees for physics majors in the
U.S., we need to generate some more interest in this subject area as the expanding world
of MRI has a tremendous need for more people ready to take this science to the next level.
So pull aside some of the top graduates from your neighborhood high schools, and encourage
them to consider this field. At first glance, physics looks like textbook-bound science.
But you might make a difference for some of these future MRI scientists by explaining how
the world of advanced medical diagnosis depends on the continuing work of MRI research,
which is almost completely led by the science of physics and medicine.
