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." ■
A PACEMAKER
THAT'S SAFE
FOR MRI
You still can't wear your favorite jewelry during an MRI scan. But if you have a heartbeathelping pacemaker or ICD (implantable
cardioverter defibrillator), you can rest easy.
That's because heart rhythm specialists at
UVA Heart & Vascular Center have developed
procedures that enable most pacemaker- and
ICD-dependent patients to undergo MRIs safely.
UVA experts were also among the first in the
nation to implant Medtronic's MRI-compatible
pacemaker in 2011, its two-lead ICD in 2015 and
now its three-lead ICD earlier this year.
UVA's ability to introduce new treatments as
soon as they are approved by the Food and Drug
Administration highlights the advantage of coming to an academic medical center. "Because we
participate in clinical trials, we gain exposure to
new technology long before it is approved," says
John Ferguson, MD. "When it is FDA-approved,
we are already familiar with the devices, enabling
us to introduce them as soon as possible."
