MRI (Magnetic Resonance Imaging)
What is a MRI?
MRI, or Magnetic Resonance Imaging, is a dynamic way
for doctors to diagnose certain problems. MRI does
not rely on X-rays. Instead, it uses strong magnets
and radio waves to create a very sharp picture of
the internal body structures. MRI uses sensitive instruments
and specially designed computers to create images
of the entire area being scanned.
What do you need to do before your MRI?
There is no special preparation necessary before
having an MRI exam. There are no restrictions on
food. You will not be allowed to wear anything metallic
during the exam. Because of the strong magnetic
field and radio frequencies, individuals who have
cardiac pacemakers cannot have an MRI done unless
your physician knows about the metallic appliance
and has approved the MRI exam. You should also be
sure that the MRI technologist knows that you have
any metallic appliances also.
