What is Magnetic Resonance Imaging (MRI)

MRI uses a magnetic field and radio waves to cause body tissues in the area being scanned to send out tiny radio signals. Each type of tissue sends out a different signal. When the system converts these signals into a computerized image, the result is a clear, exceptionally detailed "picture" of the area of interest. Image of ICAMRL certification logo

The MRI exam is particularly useful in examining the entire muscoskeletal system, internal organs in the abdomen and pelvis, and the brain and spinal cord. These detailed images allow radiologists to detect problems previously unseen with other diagnostic procedures. This can eliminate the need for a more invasive procedure or operation.

What can I expect during the exam?

A registered MRI technologist will escort you into the magnet room and position you on the table of the scanner.  Through our intercom system, you will be able to hear and talk to the technologist who will be monitoring the scan from the computer room.  During the exam you will hear a knocking sound from the MRI system that ranges from barely audible to quite noticeable, which is perfectly normal. 

Radiology Regional Center is committed to providing everyone the best MRI technology and service possible. People come in all shapes and sizes, and Radiology Regional Center makes MRI patient-friendly.

Our High Field System represents the most technologically advanced equipment available, ensuring every patient obtains state-of-the-art imaging. We are proud of our knowledgeable friendly staff, our registered technologists, and our board-certified, MRI fellowship trained radiologists

Most MRI procedures are completed within 15 to 45 minutes.



Radiology Regional Center is the first practice in the nation to install this revolutionary Siemens Magnetom Espree MRI, bringing leading edge MR technology to Southwest Floridians. This system delivers high-field MR excellence with the comfort of a wide diameter for patients of all sizes.

How do I prepare for the exam?

You cannot be examined by MRI if you have any of the following:

  • Pacemaker
  • Aneurysm clips in the brain
  • Inner ear implants
  • Metal fragments in an eye
  • Implanted spinal cord stimulator

A paramagnetic contrast agent (a special "dye" that enhances the image) may be used.
This is given intravenously before the exam to highlight certain body parts. If contrast is required for your exam, please tell your physician:

  • If you are pregnant or think you might be
  • If you are breast feeding
  • If you have anemia or any diseases that affect red blood cells
  • If you have asthma or other allergic respiratory disorders
  • If you have a renal condition or renal unsufficiencies 

Prior to your MRI examination you may eat and take your medications as you normally would.

Other questions
Are MR scans like CT scans?

No. A CT Scan is a computerized x-ray. MR scans use a strong magnetic field and harmless radio waves, so you are not exposed to radiation.
