MRI (Magnetic Resonance
Imaging) is ordered by your
physician to evaluate internal body structures without having to
use X-ray or surgery. MRI uses the physical properties of magnetic
fields, radio waves, and computers to generate images of soft
tissues within the body. MRI is a non-invasive procedure and there
are no known side or after effects.
Patients are asked to lie on a table
and remain still for approximately 30 minutes to one hour depending
on the test ordered. During the examination, a faint knocking sound
will be heard, which is normal and is the operation of the imaging
process. The images are formed from signals emitted by tissue in
the body. The MRI process captures different tissue characteristics
and translates them into different contrast levels on the
image.
