Our Magnetic Resonance
Imaging equipment detects vascular disease and problems in
the head and neck, providing doctors the information they
need for diagnosis. Once the diagnosis is made, doctors
can chart the best course of treatment.
Your doctor wants you to have a magnetic
resonance imaging (MRI) examination. MRI is one of the newest
developments in diagnostic imaging. It provides the very best
images od your body's organs and structures without using
x-rays. There are no known health risks to MRI.
FAQs
How
Does Magnetic Resonance Imaging Work?
-
Instead of using x-rays, MRI uses a
powerful magnetic field and radio frequency waves. Many
changes in tissue can be evaluated by MRI. This
information will give doctors valuable information that is
available by other diagnostic tests.
-
The body is made up of atoms. These atoms
have a magnetic charge. When the body is placed in a
strong magnetic field , these atoms tend to line up with
the magnetic field. Radio waves (similar to those used for
TV) are then sent into the body, which alters the
alignment of the atoms. When the radio waves are stopped,
the atoms generate a weak radio signal that the machine
detects. These radio signals are then put into a computer.
The result is an image that looks like the body's anatomy.
