Body Scan Centers Sprout in Upscale

Body scan centers, which offer peace
of mind to seemingly healthy people, are setting up shop in the
nation's tonier neighborhoods.
And these centers are more likely
to draw citizens who are white, rich and highly educated, says
new research from Stanford University.
"It's really the educated
wealthy of our population who are being targeted," says study
co-author Judy Illes, a senior researcher at the Stanford Center
for Biomedical Ethics. "Many of these [kinds of] services
have historically been introduced to a privileged sector of society."
But while body scan technology
is proliferating at a rapid clip, many questions still remain
about whether people need to be scanned for signs of illness when
they don't show any symptoms, Illes adds.
"We really believe that one
has to be aware of the limitations of these services as we know
them today," she says.
The entrepreneurs behind the body
scan boom have very different opinions. Over the past few years,
they've built a thriving industry out of convincing people that
disease may be silently lurking in their bodies.
Typically, patients can get CT
scans of their full bodies or specific parts, such as the heart
or lungs. The cost can run from a few hundred dollars to more
than $1,500, and some centers suggest patients get the scans
on a regular basis. Insurance companies are skeptical of the scans
and may not cover them.
Critics have charged that the scans
could produce frightening "false positives" -- misleading
signs of illness -- or lead to unnecessary medical care. The American
College of Radiology recommends against full-body scans unless
a patient actually has symptoms of illness.
Dr. Craig Bittner is chief executive
officer and medical director of AmeriScan, which operates seven
body scan centers across the country. He says the scans detect
significant medical problems in about 10 percent of patients.
"To say this is unwarranted,
that's bizarre," Bittner says. "[Doctors] screen 1,000
women with mammography before we find a breast cancer. In one
in 10 cases, we'll find a significant or life-threatening problem."
Bittner predicts Americans will
soon realize body scans should be a normal part of preventive
care. "Over 2 million Americans will die each year from cancer,
heart disease, strokes and aneurysms. Most take many years to
develop symptoms, meaning that most people who have the diseases
are walking around and feeling perfectly fine."
Bittner says he isn't surprised
by the new findings about the locations of the scan centers. "You
find them in areas where people are more sophisticated and educated,"
he says. Consumers "have to understand the value proposition
of saying, 'I feel fine, but I realize that people have disease
and feel perfectly normal.'"
The Stanford researchers used the
Internet to track down 88 body scan centers. More than a third
were in California. Then they examined the scans offered by the
centers and analyzed the economic makeup of the neighborhoods
around them.
"This is the first rigorous
study to create a map of where these centers are, what they offer
and to critically evaluate the state of the art," Illes says.
The researchers report their findings
in the August issue of Radiology.
The median household income in
the areas near the centers ranged between $36,800 and $43,800,
compared to a national median of $30,000. The regions were
78 percent to 87 percent white, compared to a national average
of 74 percent.
More than half of the centers offered
full body scans, while scans of the heart and lungs were the most
common specialized offerings.
Illes says the next step for the
researchers is to understand why a growing number of Americans
are turning to body scan centers. Meanwhile, the industry needs
to develop guidelines, especially considering that no studies
have proven that full body scans are a good idea in people who
aren't outwardly ill, she says.
Bittner points out that research
has supported the worth of scanning individual parts of the body,
although researchers haven't examined full body scans.
And what about industry guidelines?
He says they're a good idea. "Groups
have come in and offered this that don't have a lot of physician
involvement and may not have delivered the same quality of radiology
service [as we have]," he says. "Setting some standards
and guidelines would help us."
