MRI
How it works: Like CT scans,
magnetic resonance imaging
(MRI) creates cross-section
images of the body, but it uses
strong magnets and radio waves
rather than radiation to create
the images.
What it's used for: Examining
organs and diagnosing torn
ligaments, tumors, metastatic
cancer, and brain and spinal
cord conditions.
What to expect: You'll lie
on a table, and markers will be
placed on your body with tape to
indicate where the images should
focus. You'll be given earplugs,
as the machine is quite loud during testing. The table will then
slide into the machine's long,
cylindrical opening. The test can
take anywhere from 30 minutes
to two hours, depending on the
images being captured. If you
have any issues with claustrophobia or an inability to lie still
for long periods, tell your doctor.
He or she may prescribe a medication to help you relax or even
order sedation.
"MRI is a good problemsolving tool," Fishman says.
"There's no radiation involved,
and it's very good for looking at
soft-tissue changes-meniscus
tears, ligamentous injuries, spine
and disk disease-as well as cardiac function, vascular issues,
and the brain and spine." ■
WHAT ABOUT
THE RADIATION?
Many people are wary of radiation exposure
from X-rays and CT scans. And exposure builds
up over time, no matter how long you go
between tests. The average chest X-ray exposes
adults to about 0.1 millisievert (mSv) of radiation. CT scans of the chest expose adults to
about 7 mSv. Experts consider radiation exposure between 3 and 20 mSv per year to be moderate. Exposure over 20 mSv is high. Does that
mean you should avoid X-ray tests and CT scans?
"One way to look at it is not what's the risk
of the radiation-because the amount of radiation you'll get from most diagnostic tests is
fairly small-but what happens if you don't get
the test?" says James V. Rawson, MD, a radiologist and the chair of the American College of
Radiology Commission on Patient- and FamilyCentered Care. "What happens if you don't have
the information you would have gotten from
the test? The small risk you're taking with the
radiation usually does not outweigh the much
larger risk of not getting the diagnosis."
