MRI

MRI

Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor, transmitted electronically, printed or copied to a CD. MRI does not use ionizing radiation (x-rays). Detailed MR images allow physicians to evaluate various parts of the body and determine the presence of certain diseases. Source: RadiologyInfo

Our MR equipment significantly boosts our practice’s capacity to better and more timeously diagnose a variety of medical conditions, including brain and nervous
system disorder, cardiovascular disease and organ disease.Our Radiology practice is fitted with the latest in high-end software, allowing for many new clinical applications to give referring doctors increased confidence when diagnosing and treating their patients.

MRI Safety

A MRI contains a powerful magnet and great care must be taken at all times. You must inform the radiographer if you have any metal or metal implants in your body. Patients with Cochlear implants and/or Cardiac pacemakers may not be scanned in an MRI scanner.

The following may pose a risk:

  • Some artificial heart valves
  • Metal fragments in the eye
  • Implanted electronic devices ( insulin pump, nerve stimulators)
  • Some metallic prosthesis (most are MRI friendly)
  • Aneurysm clips (intracranial)
Preparing for the procedure

Guidelines about eating and drinking before a MRI scan may vary according to the specific scan that you will have. It is a good idea to inquire about it when making your appointment. The radiologist will have to know if you have any serious health problems, what surgery you may have had and if you have any allergies. All females should inform the radiographer if there is any possibility that they might be pregnant. You will be asked to change into a gown. Metal and electronic objects are not allowed in the exam room and a locker will be provided to lock these items away. Restricted items include:

  • Jewelry and watches
  • Hair pins
  • Pocket knives, firearms or any other weapons
  • Pens
  • Lighters
  • Wallets, Credit cards and coins
  • Hearing aids
  • Cellular phones
What to expect during the scan

The MRI scanner makes a noise but the scans are painless. Soft pads or ear plugs will be provided to protect your hearing. You will need to keep still for the duration of the scan as it is very sensitive to any movement.Scans vary in duration between 8 – 45 min. The radiologist or referring doctor may request that contrast media be used. This is a colour dye that we may inject intravenously during the scan. It is not done routinely but may be necessary to enhance certain anatomical structures.
