What
is an MRI?
An
MRI is a non-invasive procedure that uses radiofrequency waves
and a strong magnetic field to provide a clear and detailed
picture of the internal organs and tissues. Because MRI does
not involve radiation, it is becoming the preferred diagnostic
tool over other imaging methods. Using specialized equipment
and expertise, MRI allows for much more accurate and comprehensive
diagnosis. MRI can be used to diagnose numerous pathologic conditions
in all parts of the body, including artery disease and heart
problems, cancer, functional disorders in the lungs, liver,
kidney, spleen, pancreas and abdominal vessels, as well as joint
and musculoskeletal disorders.
How
should I prepare for the procedure?
Before
the procedure, you will be asked if you have a prosthetic hip,
pacemaker, implanted port, or artificial heart valves, pins,
screws, or surgical staples within your body. In most cases,
metal screws, plates, pins, and staples that have been in place
for more than six weeks pose no risk. If there is any question
of metal fragments, you may be asked to take an X-ray to detect
any such metal objects. Also let the board certified radiologist
know if you may be pregnant or if you have any drug allergies.
For those who may feel claustrophobic, a sedative may be administered
or you may request an "open" MRI which involves equipment that
is less confined.
How
long does an MRI take?
The
exam will generally take 15 to 45 minutes, while a very detailed
study make take longer. Several sequences to capture images
will take place during the exam, and after the exam is over,
the board certified radiologist will examine the images to determine
whether or not more images are needed.
What
happens to my results? When will my doctor get them?
After
the procedure, an experienced board certified radiologist will
examine and analyze the images and send a report with his or
her interpretation to the patient's personal physician within
24 hours.
