Magnetic Resonance Imaging (MRI) uses a strong magnetic field
rather than x-rays to produce images. MRI gives a very clear picture
of soft-tissue structures near and around bones; it is the most
sensitive exam for spinal and joint problems.
MRI produces images by focusing radiofrequency waves at protons
(the nuclei of hydrogen atoms) in a strong magnetic field. The protons
are "excited" then "relaxed" causing them to emit radio signals, which
are recorded and processed to create an image.
MRI images show the subtle differences in the tissues of the
body, even the different types of tissue within the same organ.
Because the MRI scanner uses a magnetic field to produce
images, certain types of metals cannot enter the scanning room. To
ensure patients' and the technologists' safety, a metal screening form
needs to be completed prior to the exam. This form will be completed
during the scheduling process then reviewed by the technologists upon
patient arrival.
There are no preparations for an MRI scan.
