Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI or MR) is one of the
safest, most comfortable imaging techniques available. It
combines a powerful magnet with an advanced computer
system and radio waves to produce accurate, detailed
pictures of organs and tissues in order to diagnose a
variety of medical conditions. Incorporating an advanced
technology, MRI produces images of the anatomy without the use of
radiation required with other imaging modalities such as x-ray and
CT scanning.
MRI is a non-invasive procedure with no known side or after effects.
The procedure is painless; in fact, you won't see or feel anything.
A faint knocking sound will be heard, which is simply the imaging
process in operation.

More about MRI.
Associated Radiologists
High-Field MRI and Open MRI. The different features
offered by these two types of MRI are functions of their
structural design. For many routine MRI exams, either
type can be used. However, clinical or patient-specific
considerations exist which may favor one or the other.
High-Field
MRI
High Field MRI utilizes a cylindrical tube in which the magnet is
enclosed. Patients are placed in the unit lying down,
either head first or feet first. Since this configuration
produces optimum magnetic field strength, the signal and
images produced are of the highest quality. These MRI exams
usually take 20 - 30 minutes.

Open
MRI
Open MRI scanners have a wide, non-constricting space,
making them an acceptable alternative for patients who
are severely claustrophobic or obese. Open MRI can
handle most routine studies of head, spine, neck, knee,
shoulder and other body extremities. An open MRI scan
takes approximately 45-60 minutes. Since the open sides
dissipate noise better, Open MRI tend to be quieter than
High-Field units.
Preparation for
the exam
Go on with
your normal activities, eat light meals, and take any
prescribed medications as usual. If possible, avoid
wearing cloths that have metal buckles, buttons, or
zippers. Do not use hair spray or eye makeup and please
bring your insurance information with you along with any
previous X-rays or imaging studies of the area to be
examined.
Because MRI studies produce a magnetic field, you should
remove any metallic objects such as jewelry, watches, and
hairpins. Inform the technologist of prior surgeries or
metal implants such as pacemakers or aneurysm clips.
General Prep Info
Each
type of imaging exam has its' own guidelines. Special
instructions for your exam will be given at the time of scheduling.
For certain procedures, we will contact you 24-48 hours prior to your
exam with preparation-specific instructions.
The following are a few general guidelines that apply to
every imaging exam:
-
Notify your physician and our staff if there is any
chance that you
may be pregnant or are currently breastfeeding.
-
Discuss any special needs - such as dietary and/or
physical
limitations with us in advance.
-
Check with us in advance about recovery time or if
a driver is
needed so you can make necessary arrangements with work and family.
-
Wear comfortable, metal-free clothing; be prepared
to change
into a patient gown if necessary.
-
Arrive early to verify your
registration information
and provide further health information for your exam.
-
Bring prior x-rays or scans with you to the exam
if you are
instructed to do so.
