MRI
What is MRI?
Magnetic Resonance Imaging (MRI) is a form of
imaging utilizing magnetized fields to look inside the
human body. In certain instances, a contrast injection
may be administered to enhance the study. There are
no extra precautions if your physician requires this
type of study.
A typical procedure averages 60 minutes or longer
depending on the type of scan being performed.
You will be required to remain still during the MRI
examination. Breathe normally and relax, once the
exam has begun, you will hear a knocking sound that
represents changes in the magnetic field, a normal
part of the process. During your MRI examination, a
technologist will be able to see you at all times. An
intercom system allows communication between the
patient and the technologist.
How should I prepare?
No special preparation is required prior to the MRI
exam. You may eat normally and go about your daily
routine. Continue to take any medication prescribed
by your doctor unless otherwise directed.
Prior to your exam, you will be asked to leave items
that are not compatible with a magnetic field in a safe
place outside the scan room. A list of some of these
items may include:
|
|
- Glasses
- Credit cards
- Hearing aides
|
- Keys
- Hair pins
- Other metal objects

Other items you will be asked during your interview
prior to your exam to consider are the presence of
implants and similar items. Some of these may
include the following:
- Pacemaker
- Neuro-stimulated (Tens-unit)
- Metal implants
- Intrauterine devise (IUD), etc.
