quality and coils, faster scan time, and
enhanced patient comfort—all without
a major renovation.”
With the upgrade, Professor Krestin
says the center is now back to the
level of MR imaging they historically
had—and one that is needed for a large,
tertiary pediatric academic center. “We
were limited in our imaging possibilities
in di;usion weighted and functional
imaging,” he explains. “We’ve improved
our advanced MR capabilities and
enhanced the quality to support our
clinical investigations and research

adds. “Sometimes in small children it
is di;cult to see these abnormalities.
Overall, it is easier to read the studies
and that shortens the time we need to
evaluate the patient case.”
As Erasmus continues to ramp up the
SIGNA Explorer Lift with new sequences
and capabilities, Dr. Dremmen looks
forward to using double inversion
recovery and black blood sequences,
which are not yet optimized and ready
for clinical use on the system. With the
black blood sequence, she hopes to
utilize it in place of CT for evaluation of
pediatric craniosynostosis, a condition
where one or more of the ;brous
sutures in an infant’s skull prematurely
fuses and ossi;es, changing the skull
At Erasmus an average of 50 pediatric
MR exams are performed each week.
Now with SIGNA Explorer Lift, scan
times are much shorter, requiring
less time to complete a study with
better image quality, says Ramman.
“Patient set-up is simpli;ed, and we use
Navigator for abdominal studies. We
are not scanning more patients with
the shorter scan times; we have more
time to help the patients and parents
so it’s less stressful for everyone.”
Ramman is impressed with how easy
the system is to use. “The interface is
the fastest we’ve ever seen,” she says.
“We are very pleased with the system;
with the upgrade we have better image
