Open Magnetic Resonance Imaging
What is Open MRI?
Open MRI (Open Magnetic Resonance Imaging) is a safe, non-invasive,
painless diagnostic imaging procedure that captures finely
detailed pictures of the human anatomy, including internal
organs, the nervous system, bones, and soft tissues. Unlike
X-ray or CT, MRI sees through bone to image soft tissue in
any plane of a given body part. Using a strong magnet, radio
waves and a sophisticated computer, the MRI scanner assembles
the faint signals emitted from the hydrogen atoms in your
body to create a detailed image. MRI produces cross-sectional
views of the body in "slices" which are then sent
to the computer. The computer combines these images and can
create views from any angle. MRI is used to diagnose a variety
of medical conditions, and evaluate organs, tissues and bone
structures for evidence of disease, abnormalities or injury.
MRI provides detailed images without exposure to X-ray radiation.
Open MRI (see illustration above) is different from traditional
MRI in that it has a large, non-confining opening, providing
an important option for large or claustrophobic patients.
In some cases, your doctor may order an Open MRI scan to
be done using a contrast medium to facilitate a clearer image
of the area being scanned. The contrast medium may be given
by intravenous injection or orally.
You should arrive at the center approximately 15 minutes
before your appointment time for the usual screening procedures
and paperwork. You may be asked to change into a patient gown
as metal zippers and fasteners can interfere with the scan.
At this time, you will also be asked to remove any metal objects
or items that can be affected by the magnetic field (including
hair pins, belts, jewelry, glasses, clothing with zippers,
nonpermanent dentures, credit cards, car keys). Before your
exam, the MRI technologist will obtain a brief medical history.
Let the technologist or radiologist know if you have any questions.
The MRI examination room is occupied by a large magnet and
a padded scanning table. You will be asked to lie down on
the scanning table and will be positioned to ensure maximum
comfort during your exam. The exam table will gently move
into the opening of the magnet. A coil, which is a special
radio receiver, may be placed around the body part being scanned
(such as your head, knee, chest, etc.).
You will feel nothing unusual during your exam. You will
hear humming and a rhythmic tapping noise as the scanner operates.
For added comfort, some centers may provide music or ear plugs,
or you can bring recordings of your own choosing. It is important
that you remain relaxed and still during the exam so the images
do not blur. The technologist will speak to you through a
two-way intercom system before each sequence, telling you
when the scan will begin and how long it will last. You will
be able to talk to the technologist if you need assistance
at any time during the exam. If you wish, a family friend
may accompany you into the MRI examination room, after being
If a contrast medium must be used, it will be given to you
intravenously or orally. You might experience flushing, nausea,
a headache, or a salty taste in the mouth. Let your technologist
know immediately if you experience any of these or any other
Although MRI exams are scheduled to minimize waiting time,
unexpected delays may occur. Each examination is structured
to the individual needs of the patient.
Each procedure lasts approximately 30-60 minutes. If more
than one part of the body is being imaged, the exam time may
A specially trained radiologist will review and interpret
the images and prepare a report of findings to be sent to
your referring physician within 24 hours. Your physician can
then explain to you what the findings mean.
These are general guidelines. Please contact OCMRI prior
to your appointment for detailed instructions.
In most cases, there is no advanced preparation needed for
your MRI scan. You may follow your normal diet and take any
scheduled medications. Wear something comfortable with no
metal (no zippers, etc.) Avoid make-up, as it may contain
metal. Should your physician prescribe a mild sedative, someone
will need to accompany you to escort you home. If you have
had previous diagnostic studies (CT scan, Ultrasound, X-ray,
Bone scans, or a previous MRI) of the body part being evaluated,
please bring those films and reports, or request they be sent
to the center. These studies or reports are very helpful to
the radiologist interpreting your MRI scan.
Tell your doctor or the technologist:
If you are pregnant
or breast feeding.
If you have any implanted devices such as a heart pacemaker,
internal drug-infusion pump, neurostimulator, cochlear implants,
aneurysm clips, metal plates, cardiac valves, or bone or joint
If you have had brain, heart, ear, eye or other surgeries
especially prior to 1980).
If you have been a machine, auto, or metal worker.
If you have ever been injured by metal which may still
be lodged in your body.
If you have braces or permanent bridges or hearing
If you have inferior vena cava umbrella.

Field 1.5 MRI
During an MRI exam, it is important for patients to
remain as still as possible so doctors get the clear images
they need to make an accurate assessment. That's why Orange
County MRI features the Toshiba Vantage™
1.5 MRI system designed specifically for patient
- Ultra-short bore length -- Depending on your
procedure, your head may be entirely outside the magnet.
- Ultra-wide bore -- 65cm opening provides a
spacious feeling during the exam.
- Ultra-quiet technology -- Toshiba's
Pianissimo™ (a term
meaning "very quiet") technology reduces MRI noise by as
much as 90% compared to other systems to give you a more
comfortable examination experience. This also enables
better communication between you and the technologist.
The overall goal of an MRI exam is to provide doctors
with high quality images they can use to diagnose and
evaluate your physical condition.
