"Yee
says that unlike breast cancer screening, which is meant
to find lesions early in their most treatable stage,
screening for colon cancer can actually prevent the
disease. Most colon cancers develop from polyps, she
says, and screening to find and remove these polyps
will save lives."

"However,
Kim says, only eight of every 100 people need to be
referred for polyp removal in the UW’s experience,
which consisted of more than 5,000 screened patients."

“People
have argued both sides of that,” he says, “but
a study done at the University of Wisconsin in Madison
found that when CTC and optical colonoscopy were both
available to patients, meaning that insurance coverage
was not a differential barrier, the number of [optical]
colonoscopies performed did not significantly change
up or down.”

"Dr.
Darren Schwartz from the University of Wisconsin Medical
School in Madison said that while screening endoscopy
volumes have remained stable at his tertiary care center,
about 70% more patients have been screened for colorectal
cancer following implementation of a VC screening program."

"Echoing
Schwarz's remarks, Dr. Brooks Cash, chief of gastroenterology
at the National Naval Medical Center in Bethesda, MD,
said that colorectal cancer screening at his institution
has increased by 70% since VC was added as a screening
option."

"A
representative from Colon Health Centers of America
in Newark, DE, reported that 40% of her firm's patients
said they would have opted for no colorectal cancer
screening if virtual colonoscopy were not available."

"I believe that primary 3D interpretation contributed
significantly to our excellent results (Pickhardt et al.),
and Viatronix is the only workstation able to provide
this. Other workstations offer a limited 3D capability,
but only for problem-solving of lesions detected on axial
images. 3D problem solving is useful, but only for lesions
that you identify. 3D evaluation of the entire colon is
more sensitive."
"I was skeptical of the value of a primarily 3D
based approach to virtual colonoscopy as opposed to
the more common approach with primary 2D interpretation
with 3D problem solving. But, after reading hundreds
of examinations, using first 2D followed by a 3D approach,
I can’t tell you how many times I found polyps
in 3D as large as 1cm that I had not seen on 2D –
some I couldn’t even localize retrospectively!"

"At our preventive imaging center in Denver, our
original investment in the Viatronix V3D colon package
has given us a clear competitive advantage in virtual
colonoscopy. Our radiologists find the program intuitive
and comprehensive and we now have our GI colleagues interested
in collaboration. The recent military study proving its
superior accuracy did not surprise us. The early strength
of V3D-Colon has led some to conclude that the workstation
should only be purchased for its gold standard CT colonography
module. Don't underestimate the versatility of new Viatronix
workstations – we are very impressed with its coronary
calcification imaging, body imaging and angiographic reconstruction
capabilities."

"Viatronix has the finest 3D virtual colonoscopy
system in the market today. I should know as I have a
total of 3 different workstations for our 16 slice scanner
in our clinic. I pick up significantly more polyps on
the 3D primary read study than I do examining 1000 supine
& prone images in the axial projection. In less than
2 seconds one can switch from 3D viewing to axial viewing
-making obsolete the phrase ‘2D viewing is for
diagnosis & 3D viewing is for problem solving.’
With Viatronix it is the other way around!"
