Magnetic resonance (MRI)

By appointment only

Not covered by the RAMQ

Magnetic Resonance Imaging (MRI) is a safe examination technique using magnetic field instead of ionizing radiation (X-rays). MRI has revolutionized medical imaging by its great capacity to differentiate tissues (bones, muscles, tendons, ligaments, biological fluids …).

It therefore can help diagnose some lesions that are not visible through other examination techniques such as radiography, ultrasound or Computed Tomography (CT scan).

Appointment available at the following clinics:

Radiologie LaSalle

MRI, is the technique of choice for evaluating the brain, spine, musculoskeletal system, temporomandibular joints (TMJ), blood vessels, breast, abdomen and the reproductive system. There are however a few absolute contraindications such as the presence of a pacemaker, some metal implants etc ... It is important to report any prior surgery or surgical material such aneurysm clips, implants, etc ...

Our equipment, uses advanced technology and has a large aperture of 70 cm and a short tunnel of 125 cm. It allows larger people to feel more comfortable during the exam and reduces anxiety in claustrophobic patients.

After registration, the technologist will position you so that the region to be examined is in the center of the MRI unit. At any time during the examination, you can speak with the technologist using the microphone.

Some types of examinations require the injection of a contrast agent (gadolinium), generally well tolerated, to increase the sensitivity of detection and characterization of some lesions.

It is rare for claustrophobic patients to be unable to get through an MRI exam, especially since the opening of our MRI unit is large and the tunnel is short. Our experienced staff will assist you throughout the exam. Sometimes, the prescription of an anxiolytic by your doctor might help. Should that be the case, you must be accompanied and cannot drive.

The duration of the MRI exam varies between 30 and 60 minutes.

Some are absolute contraindications: 
  • Pacemaker
  • Neurostimulator or implanted defibrillator
  • Insulin pump situated under the skin
  • Clip on a cerebral aneurysm or arteriovenous malformation.
