Sports Medicine Said to Overuse M.R.I.s

Dr. James Andrews, a widely known sports medicine orthopedist in Gulf
Breeze, Fla., wanted to test his suspicion that M.R.I.s, the scans given
to almost every injured athlete or casual exerciser, might be a bit
misleading. So he scanned the shoulders of 31 perfectly healthy
professional baseball pitchers.
.
The pitchers were not injured and had no pain. But the M.R.I.s found
abnormal shoulder cartilage in 90 percent of them and abnormal rotator
cuff tendons in 87 percent. If you want an excuse to operate on a pitchers
throwing shoulder, just get an M.R.I., Dr. Andrews says.
.
He and other eminent sports medicine specialists are taking a stand
against what they see as the vast overuse of magnetic resonance imaging in
their specialty.
.
M.R.I.s can be invaluable in certain situations finding serious problems
like tumors or helping distinguish between competing diagnoses that fit a
patients history and symptoms. They also can make money for doctors who
own their own machines. And they can please sports medicine patients, who
often expect a scan.
.
But scans are easily misinterpreted and can result in misdiagnoses leading
to unnecessary or even harmful treatments.
.
For example, said Dr. Bruce Sangeorzan, professor and vice chairman of the
department of orthopedics and sports medicine at the University of
Washington, if a healthy, uninjured person goes out for a run, a scan
afterward will show fluid in the knee bone. It is inconsequential. But in
an injured person, fluid can be a sign of a bone that is stressed or even
has a crack and is trying to heal.
.
An M.R.I. is unlike any other imaging tool we use, Dr. Sangeorzan said. It
is a very sensitive tool, but it is not very specific. Thats the problem.
And scans almost always find something abnormal, although most
abnormalities are of no consequence.
