MRI, or magnetic resonance imaging, is a method used by doctors to scan the human body to obtain diagnostic information. MRI uses magnetic field, radio waves and sophisticated computers to generate images of the inner parts of the body in a noninvasive manner.

MRI images are formed by the computer's processing of signals that are emitted by body tissue when subjected to a safe magnetic field in combination with radio waves of a specific frequency. In such a situation, different body tissues and elements emit different signals which are detected by a coil located around the body part being examined. These signals are then processed by a high powered computer to generate the images, which are then read by our radiologists to make a diagnostic report.

The earliest MRI machines used a long, closed tunnel, which required the patient to lie still while the scan was being performed. Open MRI represents an evolution of the scanner to a machine that is open on three sides. With open MRI, the patient can see his/her surroundings while the scan is in process. Due to technological advances, there is little to no difference in the diagnostic quality of the "open" image as compared to the "closed" machines.
The non-threatening experience of Open MRI makes the system ideal for children. Parents can sit and have physical contact with their children during the examination to reassure them if needed.

Open MRI offers a patient friendly environment which is ideal for children and suitable for larger patients. It is a noninvasive procedure that provides high quality imaging.

Benefits of MRI
MRI is becoming the diagnostic procedure of choice because it can often find problems which other techniques such as X-ray and CT cannot. It provides a quick and accurate diagnosis, and is safer than most other techniques, since it does not use X-rays. Use of MRI can often completely remove the need for exploratory surgery.

MRI provides early detection of disease or injury, making early treatments possible. There is no exposure to X-rays or radioactive substances during a MRI scan and the procedure is painless, accurate, quick and safe. (There are also no known side effects to using MRI.)

Any special precautions?
Patients may eat normally and go about their daily routine, both before and immediately after the examination. Medication can also be continued unless specifically advised otherwise by your doctor.

Due to the magnetic field around the equipment patients will be asked to leave any metal or magnetic items in a locker near the scan room. This includes money, keys, jewelry, watches, glasses, hair pins, and credit cards.
Patients may also be asked to remove make-up or dentures, and to wear a scrub top and/or pants to avoid magnetic interference from belt buckles and zippers. Patients will be asked whether they have any of the following, which may require special precautions:

  • Heart Pacemaker
  • Cochlear Implants
  • Neuro-Stimulators
  • Aneurysm Clips
  • Surgical Staples
  • Implanted Drug Infusion Device
  • Foreign Metal Objects in the Eye
  • Shrapnel or Bullet Wounds
  • Permanent Eyeliner

Joint replacements are not a problem, but it is useful to know if patients have them.

Pregnant patients, and anyone who works or has worked with metal, should consult their doctor for advice before scheduling a scan.
