MRI head scan
An MRI brain scan shows abnormalities in your brain and helps determine their cause (vascular, infectious, degenerative, inflammatory or tumorous). They enable your healthcare professional to assess the following areas of your brain:
- Superficial part (white matter) of the brain
- Deep part (grey matter)
- Venous and arterial vascularization
MRI brain scanning is the preferred examination for diagnosing brain conditions, for example :
- Blood clots in the brain
- Confusion, consciousness disorders (e.g. Alzheimer’s and Parkinson’s)
- Hydrocephalus (accumulation of cerebrospinal fluid in the brain)
- Tumours, infection or abscess
- Demyelinating diseases (e.g. multiple sclerosis)
For the examination procedure, you will be asked:
- to change into a hospital gown and remove your jewellery and other metal objects, which can interfere with image quality
- to lay comfortably on a mobile examination table located in a light, ventilated room. Depending on the type of examination, a contrast agent such as gadolinium may be injected in order to capture more precise images
- to wear headphones to listen to music or earplugs if you wish. The MRI machine produces a percussion sound, which may be incommodating for some patients.
- to remain still from 20 to 60 minutes, the duration of the examination.
The duration, as well as the sounds generated by the system, can make some people uncomfortable. At ImagixTM, the technologist, who watches and listens to you at all times, ensures your comfort and well-being throughout the examination.
Please note that the total duration of your visit for this examination can be between 60 and 90 minutes, even though the examination procedure itself will only last between 20 and 60 minutes.
A medical prescription is required to perform this examination.
Please note that MRI examinations are not covered by the Régie de l’assurance maladie du Québec (RAMQ). However, most group insurance plans cover the costs.
