Magnetic Resonance Imaging (MRI)

A MRI machine is a large, cylindrical machine that uses magnets and radiofrequencies to produce images of organs and structures within the body. Physicians at Christian Hospital may choose to have an MRI instead of a CT scan because bones do not obscure the images.

MRI’s cannot be performed on patients with pacemakers, intracranial aneurysm clips, cochlear implants and other types of iron-base metal implants due to the large magnets.

How is a MRI Scan Performed?

  1. Because of the strong magnetic field, the patient must remove all jewelry and metal objects during the MRI.
  2. The patient will lie on a table that slides into a tunnel in the MRI scanner.
  3. During the MRI scanning process, a clicking noise will sound as the magnetic field is created and pulses of radio waves are sent from the scanner.
  4. It is important that the patient remain very still during the examination.
  5. The diagnostic imaging technologist will be watching the patient at all times and will be in constant communication.
