Brain Computed Tomography (CT-Scan)
A brain computer tomography scan (CT-Scan) is an imaging examination that creates images of your brain in the form of thin, cross-sectional slices, in 2D or 3D. It is indicated in the case of:
- Stroke
- Transient Ischemic Attack (TIA or mini-stoke)
- Damage to the base of the skull and cranial nerves
- Epileptic seizure
- Acute and chronic headaches
- Head injury
- Suspected brain tumour
- Orbital trauma (damage to the eyes)
- Central nervous system problems
Examination procedure
For the examination procedure, you will be asked:
- to remove your jewellery and other metal objects, which can interfere with image quality
- to lay comfortably on an exam table and stay still
- to hold your breath for a few seconds, as the table will slide into the CT machine. We will capture the images very quickly to minimize the dose of radiation you absorb
Depending on the test prescribed by your health professional, it may be required to inject a contrast agent. We will go through a list of contrast agents with you when you book your appointment. If you think you may be allergic, please let us know.
Please note that the total duration of your visit for this examination can be between 30 and 60 minutes, even though the examination procedure itself will only last between 10 and 25 minutes.
Preparing for the Examination (for adults)
To prepare for the examination, we will ask you to only eat light meals on the day of the exam, such as toast, cereal, or soup (unless otherwise indicated).
A medical prescription is required to perform this examination.
Please note that CT-Scan examinations are not covered by the Régie de l’Assurance Maladie du Québec (RAMQ). However, most group insurance plans cover the costs.
