MRI – Magnetic Resonance Imaging

What is an MRI

MRI (Magnetic resonance imaging) is a method of looking inside the body.
Magnetism (instead of x-rays) is used to produce clear pictures of your head, spine, or other parts of your body and to distinguish between normal healthy tissue and diseased tissue.

MRI - Spies Radiology in Bloemfontein

An MRI is essentially a big magnet. It uses radiofrequency pulses to align certain protons in our bodies – when these pulses are stopped, the body re-aligns its protons and the energy that the body uses to do this is “read” out into the MRI machine and transformed into images that the Radiologist can interpret.

MRI imaging does NOT use any radiation and it is therefore the preferred image modality when it comes to children and infants.

Our Magnet is a tunnel – and both your head and feet will be “open” during the procedure – we might put on a head or body coil – this looks very much like a helmet. That is why, we like to think of our MRI as a “spaceship” – and most of our paediatric patient’s agree that it’s kind of “cool”.

MRI doesn’t need to be a scary experience – and it is therefore very important to read this information section so that you are well informed prior to the examination.

What happens during an MRI scan?

The technologist will position you on a special table within the magnet which is not a closed tunnel as it is open at both your feet and head area.
You will be able to communicate with the technologist during the scan.
It is important to hold very still and relax.
You may be asked to hold your breath for up to 30 seconds.
The machine makes a loud noise but the headphones provided will block out most of the noise.
MRI scan may require the use of a contrast-agent given intravenously to assist in visualization of certain structures in your body.
An examination lasts between 30 -90 minutes, depending on the body part imaged and whether contrast is required.
We adhere to the SASPI Guidelines from Red Cross Childrens War Memorial Hospital, Cape Town, for all our Paediatric imaging.

We also adhere to the RSSA guidelines in terms of Gadolinium contrast agent used and will ONLY administer contrast if it is deemed necessary for a complete examination.

MRI Scans

Finding out the results


  • Assessing the multiple images, compiling and typing the report and producing a CD with your images may take at least 40 minutes (we thank you for your patience).
  • Your referring doctor will then evaluate your images and report regarding your further management.

Important


Please inform us if any of the following applies to you, as MR works with a strong magnet:

  • Aneurysm clips(s)
  • Cardiac pacemaker
  • Implanted cardioverter defibrillator
  • Magnetically-activated implant or device
  • Neurostimulation system

  • Spinal cord stimulator
  • Cochlear implant or implanted hearing aid
  • Insulin or infusion pump
  • Implanted drug infusion device
  • Any type of prosthesis or implant

  • Artificial or prosthetic limb
  • Any metallic fragment or foreign body
  • Any external or internal metallic object
  • Other implants
  • Claustrophobia

Any metallic substance on your person can affect the quality of the diagnostic images. It can cause discomfort or even injury to you when placed inside the magnet.
Remove all: Watches, jewellery, hairpins, glasses, wallets, hearing aids, firearms, other metallic objects.
