Magnetic Resonance Imaging (MRI)

What is an MRI?
An MRI is a radiographic tool that uses a large magnet and a strong magnetic field to produce detailed images of your body. MRIs are capable of producing three dimensional images of the body for a more comprehensive diagnostic analysis. This imaging modality is principally different from a CT scan as MRI does not use x-rays. For this reason, MRIs typically take a longer period of time to perform than CT scans.

What are MRIs used for?
MRIs can help evaluate a variety of disorders within the human body including:
  • Disorders of the brain
  • Spinal cord injuries
  • Tumors
  • Strokes
  • Multiple sclerosis
  • Pathology involving the internal organs (e.g. liver, kidneys, etc.)
  • Joint disorders
What to expect for an MRI?
Dr. Khorrami will order an MRI scan when there is need for highly sophisticated imaging to diagnose a particular problem. He will look at your medical records and make sure you are able to undergo the procedure. You may have to follow specific directions before your test such as fasting for a certain number of hours prior to the procedure.

Since metal can interact with magnetic radiation, you will be required to remove anything on your body, such as a ring or piercing which contains metal. For this reason, MRIs cannot be done on any patient who has a pacemaker or defibrillator device placed in their chest. Most modern orthopedic appliances such as screws and joint hardware are safe for MRI machines. However, if you have any such pieces of metal inside of you then you need to alert Dr. Khorrami and the MRI technologist so proper safety evaluations can be undertaken. You may be required to remove your clothing and wear a gown for the procedure.

During your procedure, you may be administered a contrast material or dye that is used to enhance the quality of your images for better interpretation. You may be required to follow specific instructions during your examination, such as staying still for the duration of the test. The MRI machine makes odd noises throughout the testing period and the cavity you lay in may feel restrictive. If you believe you will have trouble keeping still, then Dr. Khorrami may administer a small sedative to help you relax during the procedure. MRIs are non-invasive and painless, with the entire procedure lasting around 30-60 minutes.

Are there any risks associated with an MRI?
Magnetic radiation is painless and harmless and the only reaction would be from a metal object that was not removed prior to the procedure. However, some people may not tolerate the noise and restricted surroundings in an MRI machine. Also, some may experience a reaction to he contrast dye that is used to enhance the quality of the images.
