No
special preparation is needed for the exam. Eat normally and
take any medications that you usually take.
If you
are having a brain MRI please do not wear any makeup as it
may interfere with the exam.
If you
are having an exam with contrast, please do not eat or drink
2 hours before your exam.
If you
have any other question please call your medical imaging center.

Almost
everyone can have an MRI with complete safety. The technologist
will ask certain questions about your medical history to ensure
the best possible results from your exam.
Patients
with the following conditions are not candidates for MRI:
- Patients
with cardiac pacemakers, neuro-stimulators or other electrical
devices in their bodies.
- Patients
with cerebral aneurysm clips are sometimes excluded.
- Pregnant
women are generally not recommended for MRI scans. Be sure
to inform your physician and the MRI Center staff if you
are pregnant.

MRI
is considered a safe test, and there is no ionizing radiation
used. However, conclusive evidence showing how safe MRI is
for pregnant women and the fetus, is not yet available. MRI
is generally not performed during the first twelve weeks of
pregnancy (first trimester).
Generally,
we do not perform MRI on pregnant women, unless there is a
strong medical indication. Prior to the test, you may want
to discuss this with your obstetrician, and the radiologist.
Depending on the condition, other tests, including ultrasound,
may be available to diagnose a medical condition.

Yes.
The MRI examination poses no risk to the average patient if
appropriate safety guidelines are followed.
Post-cardiac
surgery patients and patients with the following medical devices
can be safely examined with MRI:
* Surgical
clips or sutures
* Artificial joints
* Staples
* Cardiac valve replacements
* Disconnected medication pumps
* Vena cava filters (after 6 weeks for certain types)
* Brain shunt tubes for hydrocephalus
* Metal stents
Some
conditions may make a MRI examination inadvisable. Tell your
doctor if you have any of the following conditions:
* Heart
pacemaker
* Cerebral aneurysm clip (metal clip on a blood vessel in
the brain)
* Pregnancy
* Implanted insulin pump (for treatment of diabetes), narcotics
pump (for pain medication), or implanted nerve stimulators
("TENS") for back pain
* Metal in the eye or eye socket
* Cochlear (ear) implant for hearing impairment
* Implanted spine stabilization rods
* Severe lung disease (such as tracheomalacia or bronchopulmonary
dysplasia)
* Gastroesophageal reflux
* Weight of more than 300 pounds
* Inability to lie on back for 30 to 60 minutes
* Claustrophobia (fear of closed or narrow spaces).

Most
MRI scans are finished within 30-45 minutes … depending
upon the study being performed. Allow 2 - 3 hours for the
visit to most Medical Imaging Centers.

MRI
stands for Magnetic Resonance Imaging, the latest and most
advanced type of diagnostic scanning. MRI forms "images,"
or pictures, of the internal structures of the body.
MRI uses
radio waves, a powerful electromagnet and a computer to view
the soft tissue of the body. MRI is capable of diagnosis and
assessment of many diseases earlier than other diagnostic
techniques.
You may
already be familiar with CT scanning, which uses X-rays to
study tissues. MRI uses a similar computerized process, but
introduces a technology that images your body organs and chemistry
without radiation.

What can I expect during an MRI examination? |

MRI causes
no pain but some patients can find it uncomfortable to remain
still during the examination. Others experience a sense of
being "closed in," though the more open construction
of newer MRI systems has done much to reduce that reaction.
You may notice a warm feeling in the area under examination;
this is normal but if it bothers you the radiologist or technologist
should be notified.
If a contrast
injection is needed, there may be discomfort at the injection
site and you may have a cool sensation at the site during
the injection. Most bothersome to many patients are the loud
tapping or knocking noises heard at certain phases of imaging.
Ear plugs may help.
