Melany Atkins, MD, Director of
Cardiac Imaging, FRC, specializes
in cardiac and body MR and cardiac
CT. While she ;rst started using
Vios Works on a Discovery™ MR750w
3.0T scanner in early 2016, there has
been a signi;cant uptick in utilization
beginning in May 2016.
“The use of Vios Works has evolved in
our practice and we’ve started using
it on all cardiac MR exams to help
improve the quality of the sequence
at our facility,” Dr. Atkins says. “It also
enables the technologist to be more
comfortable acquiring the images.”
Beginning in June, Dr. Atkins and her
colleagues began using the Vios Works
imaging data to support their patient
management decisions. The 40
patients imaged so far represent a
wide range of conditions, including
normal patients without valvular
disease and adults and pediatrics
with congenital heart disease.
“We are very happy with the results and
we are relying on the ;ow data that we
acquire, more so than the traditional
data,” she adds.
The most signi;cant bene;t is the
reduction in time to acquire the 4D
Flow/Vios Works study. Currently, the
4D Flow portion of the exam is between
7. 5 and 8. 5 minutes with no breath holds.
Dr. Atkins believes that as the practice
continues to use Vios Works, they may be
able to reduce many of the traditional
sequences and signi;cantly reduce
scan time. “As the contrast resolution
continues to improve, we can
potentially reduce many of the
sequences we are currently acquiring.”
Vios Works may be bene;cial for the
clinician’s productivity as well; Dr. Atkins
cannot always be present at the scanner
for an entire CMR study. Prescription of
the image plane is important to obtain
a true double oblique image, otherwise
it is possible for the ;ow data to
“The beauty of Vios Works is that it
acquires ;ow data for the entire data
set. I can then go back and process
the data after the fact,” she explains.
Plus, since the sequence acquires
comprehensive ;ow data, if a clinical
question is raised after the exam, she
can go back and perform additional
measurements. In addition, there is no
risk of being in the wrong imaging plane.
“If we acquire 4D Flow, then I know we
will have good ;ow data. I can go back
to the data set and process additional
;ow information from any vessel in
the ;eld of view. From that point, I’m
much less nervous when evaluating a
complex congenital heart,” she adds.
Also impressive is the Arterys
cloud-based processing, adds Dr.
Atkins. What once took hours of
computer processing time now can
be accomplished in minutes. The
technologists at FRC love the solution
as well—they simply acquire the data
and then upload it. “That part is just
amazing. And, with everything cloud-based, it is so easy to access from any
location,” she adds.
“Vios Works is a technology that may be
able to change our practice,” Dr. Atkins
says. “It adds great value in both our
pediatric and adult cardiac cases.”
