Magnetic Resonance Imaging

Magnetic Resonance Imaging

MRI is one of the most advanced imaging tools for physicians today. It allows your physician to view the inside of your body without invasive surgery or the use of ionizing radiation. MRI uses a powerful magnet, radio frequency waves and computer technology to create detailed cross-sectional images of the muscles, nerves and bones in the specific area of interest being scanned.

How MRI Scanners Work

The main component of the MRI system is the magnet. The magnet causes the hydrogen atoms in you body to align themselves in such a way as to receive radio signals from the magnet’s resonance system. When the signal ceases, the atoms begin releasing energy as they move. This energy becomes the data interpreted by the computer into an image we understand.

Understanding Contrast Media

Certain types of MRI exams require the use of a safe paramagnetic agent (contrast media) called gadolinium. This agent, which is given intravenously during the study, highlights the area of concern. If you are breast feeding, pregnant (or suspect you may be), have kidney disease or have questions about your eligibility to receive contrast media, please discuss your concerns with the MRI staff or your physician.

The Actual Exam

Your MRI exam is really quite simple. With the assistance of the MRI technologist, you will be positioned on a padded table. The table will move slightly and your exam will begin.

During your MRI, you may notice loud knocking or mild vibration of the table as the information is obtained. This is normal and you will be provided with hearing protection. In most cases, we are able to offer music instead.

Your technologist will conduct the study from an adjacent room and is able to communicate with you through the intercom. You can be seen and heard by your technologist at all times during the exam.

The study will take anywhere from 20 to 60 minutes, depending on the area being studied. You will receive a copy of your images to take with you when you leave. Our Board Certified Radiologists will dictate a report and fax the results to your physician, often within 24 hours.

What Is Ionizing Radiation?

Ionizing radiation is radiation composed of particles that individually have sufficient energy (or can liberate sufficient energy) to remove an electron from an atom or molecule. This ionization produces free radicals, which are atoms or molecules containing unpaired electrons. These tend to be especially chemically reactive, and they account for most of the unusually high biological damage of ionizing radiation.

MRI does not use any ionizing radiation.
