A key exam to detect a recent or past stroke

A CT brain scan – stroke protocol is a medical imaging exam used to quickly detect the presence of a stroke, whether ischemic (caused by a blocked blood vessel) or hemorrhagic (caused by bleeding). This exam uses computed tomography (CT scan) to produce detailed images of the brain in just a few minutes.

What is the purpose of this exam?

The main objectives of this type of CT scan are to:

  • Confirm or rule out the presence of a stroke
  • Determine whether the stroke is ischemic or hemorrhagic
  • Rapidly guide medical intervention when urgent care is required
  • Detect a past or silent stroke
  • Monitor the progression of an already diagnosed stroke
  • Investigate persistent symptoms such as memory loss or cognitive impairment

When is this exam ordered?

In emergency situations

The CT brain scan – stroke protocol is the first-line exam when a stroke is suspected in an emergency context. It is prescribed when the following symptoms appear suddenly:

  • Weakness or numbness on one side of the body
  • Difficulty speaking or understanding speech
  • Vision loss
  • Sudden and severe headaches
  • Loss of balance or severe dizziness

In these situations, the scan enables rapid diagnosis and helps determine whether emergency treatment, such as thrombolysis or thrombectomy, is possible.

Non-urgent situations

Outside of emergency care, a CT brain scan – stroke protocol may be prescribed to:

  • Perform a neurological assessment after past symptoms
  • Look for signs of previous strokes or silent brain lesions
  • Evaluate the effectiveness of a treatment or the progression of a neurological condition
  • Investigate persistent symptoms such as:
    • Dizziness
    • Memory issues
    • Confusion
    • Behavioral or cognitive changes

Who can prescribe this exam?

A valid medical referral is required for this exam. It may be prescribed by:

  • A family physician
  • A neurologist
  • An emergency physician
  • Any other healthcare professional authorized to prescribe medical imaging exams
