Magnetic Resonance Imaging (MRI)

What is an MRI?
MRI,
magnetic resonance imaging, is a method used by physicians to look
inside the human body to obtain diagnostic information. Incorporating
an advanced technology, MRI produces images of the anatomy without the
use of radiation found in X-rays and CT scanning. MRI uses a computer
and the physical properties of magnetic fields to generate images of
the soft tissues within the body. It can help provide a quick and
accurate diagnosis, which in some situations can reduce the need for
exploratory surgery How long does each MRI take?
and other
diagnostic procedures. MRI is a non-invasive procedure, and there are
no known side effects. In fact, you won’t see or feel anything
uncomfortable during the scan.
What kind of problems can be detected by an MRI?
An
MRI is used for all parts of the body and is effective in the clinical
evaluation of many conditions including brain disorders, spine
diseases, tumor detection, knee and shoulder injuries, musculoskeletal
disorders, infection, facial/neck abnormalities and liver diseases.
What can I expect during the procedure?
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 physician unless otherwise directed.
Because of the magnetic field, you will be asked to leave the following
items in a safe place outside the scan room: coins, jewelry, watches,
glasses, credit cards, hearing aides, keys, hair pins and other metal
objects. You may be asked to wear a gown to avoid magnetic interference
from belt buckles and zippers. Once you are situated on the table, make
sure you are comfortable so that it is easy to keep still. Breathe
normally. There is nothing about the procedure to make you
uncomfortable. The only thing you will notice is a faint knocking sound
that represents the scanning process.
Is there anything I should tell the technologist?
Because
of the strong magnetic field in the MRI you should tell the physician
and technologist about any head surgery (brain, eye, ear), pacemaker,
neuro-stimulator, metal implant, aneurysm clips, implanted drug
infusion device, spinal cord stimulator, metal object in the eye and
surgical staples. Please refer to the MRI checklist given to you by the
technologist for the full list of metallic objects. If you are
pregnant, please notify the technologist and your physician.
